A Randomized Controlled Trial of Topical Analgesia Post-Hemorrhoidectomy (TAPH Trial).

BACKGROUND: Postoperative pain remains the greatest problem after hemorrhoidectomy. Pain is hypothesized to arise from bacterial infection, sphincter spasm, and local inflammation. OBJECTIVE: A randomized controlled factorial trial was conducted to assess the effects of metronidazole, diltiazem, and lidocaine on post-hemorrhoidectomy pain. DESIGN: A double blinded randomized controlled factorial trial. SETTINGS: A multicenter trial was conducted in Auckland, New Zealand. PATIENTS: 192 Participants were randomized (1:1:1:1) into four parallel arms. INTERVENTIONS: Participants were randomized into one of four groups receiving topical treatment with 10% metronidazole (M), 10% metronidazole + 2% diltiazem (MD), 10% metronidazole + 4% lidocaine (ML), or 10% metronidazole + 2% diltiazem + 4% lidocaine (MDL). Participants were instructed to apply to the anal verge 3 times daily for 7 days. MAIN OUTCOME MEASURES: The primary outcome was pain on the visual analogue scale on day 4. The secondary outcomes included analgesia usage, pain on bowel motion, and functional recovery index. RESULTS: There was no significant difference in the pain and recovery scores when diltiazem or lidocaine was added to metronidazole (score difference between presence and absence of D in the formulation: -3.69, 95% CI: -13.3, 5.94, p = 0.46; between presence and absence of L: -5.67, 95% CI: -15.5, 3.80, p = 0.24). The combination of MDL did not further reduce pain. Secondary analysis revealed a significant difference between the best (ML) and worst (MDL) groups in both pain and functional recovery scores. There were no significant differences in analgesic usage, complications, or return to work between the groups. No clinically important adverse events were reported. The adverse event rate did not change in the intervention groups. LIMITATIONS: Topical metronidazole was utilized in the control group, rather than a pure placebo. CONCLUSION: There was no significant difference in pain when topical diltiazem or lidocaine, or both, was added to topical metronidazole. CLINICAL TRIAL REGISTRATION IDENTIFIER: NCT04276298.

Inequities in colonoscopy access: a retrospective audit of accepted referrals in Te Whatu Ora Counties Manukau.

AIM: Maori are more likely to have colorectal cancer (CRC) diagnosed in the emergency setting.[[1]] CRC patients diagnosed in the emergency setting have a higher stage, increased surgical complications and worse survival than those diagnosed elsewhere.[[2]] Access to colonoscopy is crucial to diagnosing CRC prior to an emergency presentation. This study aims to assess inequities in access to symptomatic and surveillance colonoscopies. METHODS: A retrospective audit of all accepted referrals for symptomatic and surveillance colonoscopies made in Te Whatu Ora Counties Manukau in 2018 (n=7,184) with analysis by multivariate logistic regression. RESULTS: Of the 751 Maori patients, 33.4% were removed off the waiting list and therefore did not have their colonoscopy performed, compared to 24.1% of the 4,047 NZ European patients. Maori patients were significantly more likely to be removed off the waiting list than NZ European patients with an adjusted odds ratio of 1.68 (95% confidence interval [CI] 1.40-2.02). Pasifika patients were significantly more likely to be removed off the waiting list than NZ European patients with an adjusted odds ratio of 2.30 (95% CI 1.92-2.75). CONCLUSIONS: Maori have significantly less access to colonoscopies than NZ Europeans. We suggest improvements to referral systems locally and nationally to facilitate equitable access.

Causes and costs of delayed closure of ileostomies in rectal cancer patients in Australasian units.

BACKGROUND: Defunctioning loop ileostomies (DLIs) are a frequent adjunct to rectal cancer surgery. Delayed closure of DLIs is common and associated with increased morbidity. The reasons for delayed DLI closure are often unknown. The economic burden of delayed DLI closure is not quantified. The present study aimed to determine the reasons for, and economic burden of, delayed DLI closure. METHODS: Clinical and economic data were audited from a prospective database of patients in two Australasian colorectal cancer centres. Patients treated at each unit with low/ultra-low anterior resection for rectal cancer with formation of DLI between January 2014 and December 2019 were included. Post-operative complication rate, stoma-related complication rate and costs of hospital admissions and stoma care were recorded and analysed. Multivariate linear regression analysis was used to investigate risk factors for delay to closure. RESULTS: 146 patients underwent low/ultra-low anterior resection with DLI; 135 patients (92.5%) underwent reversal. The median duration to reversal was 7 months (IQR 4.5-9.5). Sixty-six percent of patients underwent reversal >6 months after their index surgery. Neoadjuvant and adjuvant chemotherapy were associated with delayed reversal (P < 0.001). Non-English speakers waited longer for DLI closure (P = 0.028). The costs of outpatient stoma care (P < 0.001), post-operative care (P = 0.004), and total cost of treatment (P = 0.014) were significantly higher in the delayed closure group, with a total cost of treatment difference of $3854 NZD per patient. CONCLUSIONS: Causes of delay include systemic factors and demographic factors that can be addressed directly, addressing such causes may alleviate a significant economic burden.

Changing the routine: a move to patient initiated follow up to improve surgical outpatient clinic.

INTRODUCTION: Patient initiated follow up (PIFU) allows patients to initiate a hospital follow up appointment on an 'as required' basis in contrast to the traditional physician-initiated model. We present a clinical pathway for patients referred with rectal bleeding at a large tertiary public hospital in South Auckland, New Zealand and demonstrate the utility of PIFU and its impact on reducing follow up appointments. METHOD: The purpose of the pathway was to allow standardized care by the clinicians and allow for PIFU. Two separate protocols were developed - 'Painful PR bleeding' and 'Painless PR bleeding'. A new clinic (NC) was started following these protocols, and this was compared to historical controls (HC). The primary outcome was the rate of follow up appointments. RESULTS: There were 133 patients in the NC and 135 in the HC, with significantly less follow ups in the NC (6% versus 45%, p < 0.0001). A small percentage of patients in the NC group were directly discharged (10%) whilst 70% of patients were discharged with a PIFU card. Thirty phone calls were made using PIFU, with 10 patients returning to clinic and 20 requiring advice and reassurance only. At 5 year follow up, there was a single colorectal malignancy found in both groups. CONCLUSION: Initiating a protocol that includes patient initiated follow up vastly reduces the need for routine return to clinic for the majority of patients, without sacrificing patient care. A protocolised approach to clinic for other areas in general surgery should be considered.

Intravenous Local Anesthetic Compared With Intraperitoneal Local Anesthetic in Laparoscopic Colectomy: A Double-blind Randomized Controlled Trial.

INTRODUCTION: Controlling perioperative pain is essential to improving patient experience and satisfaction following surgery. Traditionally opioids have been frequently utilized for postoperative analgesia. Although they are effective at controlling pain, they are associated with adverse effects, including postoperative nausea, vomiting, ileus, and long-term opioid dependency.Following laparoscopic colectomy, the use of intravenous or intraperitoneal infusions of lidocaine (IVL, IPL) are promising emerging analgesic options. Although both techniques are promising, there have been no direct, prospective randomized comparisons in patients undergoing laparoscopic colon resection. The purpose of this study was to compare IPL with IVL. METHODS: Double-blinded, randomized controlled trial of patients undergoing laparoscopic colonic resection. The 2 groups received equal doses of either IPL or IVL which commenced intra-operatively with a bolus followed by a continuous infusion for 3 days postoperatively. Patients were cared for through a standardized enhanced recovery after surgery program. The primary outcome was total postoperative opioid consumption over the first 3 postoperative days. Patients were followed for 60 days. RESULTS: Fifty-six patients were randomized in a 1:1 fashion to the IVL or IPL groups. Total opioid consumption over the first 3 postoperative days was significantly lower in the IPL group (70.9 mg vs 157.8 mg P < 0.05) and overall opioid consumption during the total length of stay was also significantly lower (80.3 mg vs 187.36 mg P < 0.05. Pain scores were significantly lower at 2 hours postoperatively in the IPL group, however, all other time points were not significant. There were no differences in complications between the 2 groups. CONCLUSION: Perioperative use of IPL results in a significant reduction in opioid consumption following laparoscopic colon surgery when compared to IVL. This suggests that the peritoneal cavity/compartment is a strategic target for local anesthetic administration. Future enhanced recovery after surgery recommendations should consider IPL as an important component of a multimodal pain strategy following colectomy.

How do New Zealand-trained general surgeons secure a SMO job? Are we effectively retaining our trainees?

BACKGROUND: In the context of increasing shortages in the New Zealand medical specialist workforce, this research seeks to answer the question 'Are we effectively retaining our New Zealand-trained general surgeons?' METHODS: Semi-structured interviews were undertaken with 16 general surgeons. Participants work in New Zealand and internationally. Interviews were transcribed, coded and themed. Thematic analysis was used to interpret the findings. RESULTS: This research finds that we are failing to effectively retain New Zealand-trained general surgeons through haphazard workforce planning and a lack of transparent recruitment processes. General surgeons who choose to take their first SMO role overseas are pushed to do so due to a lack of certainty about job opportunities in New Zealand, bullying, and relative ease of negotiation for job composition and conditions at international hospitals. General surgeons who take their first SMO role in New Zealand feel that securing a job is down to luck, existing relationships with influential people in surgical departments and timing. CONCLUSION: The failure to retain New Zealand-trained general surgeons in the New Zealand specialist workforce is amenable to improvements in workforce planning, improved coordination between clinical and administrative leadership in DHBs, and better career development support for trainees prior to receiving their FRACS and embarking on post-fellowship subspecialist training. Further research into the experiences of trainees and SMOs in general surgery and other surgical subspecialties is required to build a complete picture of the path from trainee to SMO, and areas where interventions could improve retention of New Zealand-trained general surgeons.

A systematic review and meta-analysis of the efficacy of topical sphincterotomy treatments for anal fissure.

BACKGROUND: Anal fissure is a common condition that can be treated medically or surgically. Chemical sphincterotomy is often used before surgical intervention. This study aims to evaluate the effectiveness of topical agents for chemical sphincterotomy on healing of anal fissures and side-effects. METHODS: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) compliant systematic review was performed using MEDLINE, EMBASE, Scopus, and CENTRAL databases. Eligible studies included randomized controlled trials which compared topical sphincterotomy agents with topical placebo agents or each other. Studies that included surgical treatments were excluded. Overall evidence was synthesized according to the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. RESULTS: Thirty-seven studies met the study selection criteria. Seventeen studies show that glyceryl trinitrate (GTN) was significantly more likely to heal anal fissure than placebo (relative risk (RR) = 1.96, 95% confidence interval (95%CI) = 1.35-2.84, I2 = 80%). Eleven studies showed a marginally significant difference between healing rates for diltiazem vs GTN, RR = 1.16, (1.01-1.33) I2 = 48%. There was no significant difference in healing between diltiazem and placebo, RR = 1.65, (0.64-4.23), I2 = 92%. GTN significantly reduced pain on the visual analog scale compared to the placebo group, MD-0.97 (-1.64 to -0.29) I2 = 92%. There was high certainty of evidence that GTN was significantly more likely to cause headache than placebo (RR = 2.73 (1.82-4.10) I2 = 58%) and diltiazem RR = 6.88 (2.19-21.63) I2 = 17%. CONCLUSION: There is low certainty evidence topical nitrates are an effective treatment for anal fissure healing and pain reduction compared to placebo. Despite widespread use of topical diltiazem, more evidence is required to establish the effectiveness of calcium channel blockers compared to placebo.

Barriers and facilitators for Maori in accessing hospital services in Aotearoa New Zealand.

AIM: This paper reports the findings of a literature review to answer the research question, "What are the barriers and facilitators of access to hospital services for Maori?" METHOD: MEDLINE (Ovid) and PsycINFO were searched using keywords to identify relevant literature published between 2000 and 2020. The data analysis was informed by a Kaupapa Maori positioning and the CONSIDER statement on reporting of health research involving Indigenous peoples. RESULTS: Twenty-three papers met the inclusion criteria. We identified five themes that captured the barriers for Maori accessing hospital services (practical barriers, poor communication, hostile healthcare environment, primary care barriers and racism) and five facilitatory themes were identified (practical facilitators, whakawhanaungatanga, whanau, manaakitanga and cultural safety). CONCLUSION: This article confirms existing knowledge about practical barriers and facilitators to healthcare access for Maori and contributes to an emerging body of evidence about the impact of racism and culturally unsafe services in preventing Maori from accessing healthcare services. The facilitators identified provide a potential roadmap for the redesign of services so they are accessible and effective for Maori. Improving services in this way would support district health boards, the Ministry of Health and professional organisations to comply with their commitments to providing culturally safe services and health professionals.

Warm-up before laparoscopic surgery is not essential.

BACKGROUND: Several recent studies have suggested that warming up prior to surgery may improve surgical performance. The purpose of this study was to investigate whether warming up prior to laparoscopic surgery improves surgical performance or reduces surgery duration. METHODS: Between August 2011 and January 2012, a randomized controlled trial was conducted to compare two warm-up modalities to no warm-up. The study was conducted at a single site, with nine surgeons performing 72 laparoscopic cholecystectomies and 37 laparoscopic appendicectomies. Prior to surgery, surgeons were randomized to either laparoscopic trainer box warm-up, PlayStation 2 warm-up or no warm-up. The activity was performed within 30 min of surgery commencing. Patients provided informed consent for the surgery to be digitally recorded. Digital videodiscs (DVDs) were reviewed by an independent and blinded assessor. Data were collected on duration of surgery, level of training and perceived surgical difficulty. Surgical performance was graded using a validated scoring system. RESULTS: From the 109 operations performed, there were 75 usable DVDs. Overall, there were no statistical differences in the demographics of patients and surgeons in the three treatment groups, nor in the subset that had useable DVDs. There were no statistical differences in the duration of surgery or surgeon's perceived surgical difficulty. There was no statistical difference in surgical performance. CONCLUSIONS: This study suggests that warm-up prior to laparoscopic cholecystectomy or appendicectomy is not essential, acknowledging that there are several study limitations that preclude definitive conclusion.
