Pre-operative erector spinae plane block should be considered a viable option for laparoscopic colectomies.

BACKGROUND: The Erector Spinae Plane (ESP) block is a recent development in the field of regional anaesthesia and has been increasingly explored for abdominal surgeries to reduce opioid use and improve pain control. Colorectal cancer is the commonest cancer in multi-ethnic Singapore and requires surgery for curative treatment. ESP is a promising alternative in colorectal surgeries, but few studies have evaluated its efficacy in such surgeries. Therefore, this study aims to evaluate the use of ESP blocks in laparoscopic colorectal surgeries to establish its safety and efficacy in this field. METHODS: A prospective two-armed interventional cohort study comparing T8-T10 ESP blocks with conventional multimodal intravenous analgesia for laparoscopic colectomies was conducted in a single institution in Singapore. The decision for doing an ESP block versus conventional multimodal intravenous analgesia was made by a consensus between the attending surgeon and anesthesiologist. Outcomes measured were total intra-operative opioid consumption, post-operative pain control and patient outcome. Post-operative pain control was measured by pain score, analgesia use, and amount of opioids consumed. Patient outcome was determined by presence of ileus. RESULTS: A total of 146 patients were included, of which 30 patients received an ESP block. Overall, the ESP group had a significantly lower median opioid usage both intra-operatively and post-operatively (p = 0.031). Fewer patients required patient-controlled analgesia and rescue analgesia post-operatively for pain control (p < 0.001) amongst the ESP group. Pain scores were similar and post-operative ileus was absent in both groups. Multivariate analysis found that the ESP block had an independent effect on reducing intra-opioid consumption (p = 0.014). Multivariate analysis of post-operative opioid use and pain scores did not yield statistically significant results. CONCLUSIONS: The ESP block was an effective alternative regional anaesthesia for colorectal surgery that reduced intra-operative and post-operative opioid use while attaining satisfactory pain control.

Systematic review and meta-analysis of postoperative pain and symptoms control following laser haemorrhoidoplasty versus Milligan-Morgan haemorrhoidectomy for symptomatic haemorrhoids: a new standard.

PURPOSE: Haemorrhoidal disease (HD) plagues one in every ten people, with a plethora of surgical treatment modalities, of which laser haemorrhoidoplasty (LHP) is a relatively novel option. This systematic review and meta-analysis objectively evaluated the efficacy, safety, and tolerability of LHP compared against conventional (Milligan-Morgan) open haemorrhoidectomy (CoH). METHOD: A comprehensive search of MEDLINE, EMBASE, CENTRAL, and Google Scholar was conducted. Randomised controlled trials (RCTs) and comparative cohort studies (CCSs) which compared LHP against CoH were included, with postoperative pain as the primary outcome. Secondary outcomes included intraoperative characteristics, short- and moderate-term outcome, and complications. RESULTS: A total of 12 studies (6 RCTs and 6 CCSs), with a total of 1824 patients, were analysed. LHP resulted in reduced postoperative pain for the first day (mean difference of 2.07 visual analogue scale units), week, and month. The mean dosage and duration of postoperative analgesia use was similarly lower, with a mean difference of 4.88 mg (morphine) and 2.25 days, respectively. Crucially, recurrence was equivocal (HR: 0.72, CI: 0.21-2.40) at a mean follow-up duration of 8.58 ± 9.55 months. LHP resulted in lower blood loss and was 12.74 min shorter on average. LHP's postoperative recovery time was 9.03 days less with equivalent or decreased risk of most short- and moderate-term complications except anal thrombosis. CONCLUSION: Our study suggests that LHP is more tolerable than CoH, providing patients with superior postoperative quality of life at equivalent moderate-term efficacy. These findings contribute to improved understanding of LHP and its potential at enhancing the quality of HD care.

Did the COVID-19 lockdown result in a delay of colorectal cancer presentation and outcomes? A single centre review.

PURPOSE: The COVID-19 pandemic and resultant lockdown measures potentially delay management of non-communicable, life-limiting diseases like colorectal cancer (CRC) through avoidance of healthcare facilities by the public and diversion of resources within healthcare systems. This study aims to evaluate the impact of Singapore's "Circuit Breaker (CB)" lockdown measures on CRC disease presentation and short-term surgical outcomes, while comparing Singapore's approach against other countries which employed similar lockdown measures. METHODS: Patients whose initial diagnosis of CRC was made within the 6-month pre-CB (6/10/19-6/4/20) ("pre-CB group") and post-CB (7/4/20-7/10/20) ("post-CB group") period were enrolled retrospectively. The groups were compared based on severity of disease on presentation and short-term operative outcomes. RESULTS: In total, 105 patients diagnosed with CRC were enrolled in this study. When comparing pre-CB and post-CB groups, there was no significant difference in stage of CRC on presentation (p = 0.850). There was also no increase in need for emergent operations (p = 0.367). For patients who had undergone an operation, postoperative morbidity was not significantly higher in the post-CB group (p = 0.201). Both groups of patients had similar length of stay in the hospital (p = 0.438). CONCLUSION: Unlike similar high-income countries, Singapore did not see later stage disease on presentation and poorer operative outcomes after lockdown measures. Possible reasons include lesser healthcare avoidance behaviours amongst Singaporeans, and adequate preparation of resources and contingency plans formed by hospitals after previous pandemics.

Primary Tumor-Related Complications and Salvage Outcomes in Patients with Metastatic Rectal Cancer and an Untreated Primary Tumor.

BACKGROUND: For rectal cancer with unresectable metastases, current practice favors omitting interventions directed at the primary tumor in asymptomatic patients. OBJECTIVE: This study aimed to determine the proportion of patients with primary tumor-related complications, characterize salvage outcomes, and measure survival in patients with metastatic rectal cancer who did not undergo upfront intervention for their primary tumor. DESIGN: This is a retrospective analysis. SETTING: This study was conducted at a comprehensive cancer center. PATIENTS: Patients who presented between January 1, 2008, and December 31, 2015, with synchronous stage IV rectal cancer, an unresected primary tumor, and no prior primary tumor-directed intervention were selected. MAIN OUTCOME MEASURES: The main outcome measured was the rate of primary tumor-related complications in the cohort that did not receive any primary tumor-directed intervention. The Kaplan-Meier method and Cox regression analysis were used to determine whether complications are associated with survival. RESULTS: The cohort comprised 358 patients with a median age of 56 years (22-92). Median follow-up was 26 months (range, 1-93 months). Among the 168 patients (46.9%) who eventually underwent elective resection of the primary tumor, the surgery was performed with curative intent in 66 patients (18.4%) and preemptive intent in 102 patients (28.5%). Of the 190 patients who did not undergo an upfront or elective intervention for the primary tumor, 68 (35.8%) experienced complications. Nonsurgical intervention for complications was attempted in 34 patients with an overall success rate of 61.8% (21/34). Surgical intervention was performed in 47 patients (including 13 patients for whom nonsurgical intervention failed): diversion in 26 patients and resection in 21 patients. Of those 47 patients, 42 (89.4%) ended up with a colostomy or ileostomy. LIMITATIONS: This study was conducted at a single center. CONCLUSION: A significant proportion of patients with metastatic rectal cancer and untreated primary tumor experience primary tumor-related complications. These patients should be followed closely, and preemptive intervention (resection, diversion, or radiation) should be considered if the primary tumor progresses despite systemic therapy.

Study Protocol for the Use of Conventional Open Haemorrhoidectomy versus Laser Haemorrhoidoplasty in the Treatment of Symptomatic Haemorrhoids: A Randomized Controlled Trial.

BACKGROUND: Haemorrhoids result in a variety of symptoms that cause significant patient anxiety. Treatment has long been associated with post-operative complications, which cause significant symptoms and may result in readmissions. The open conventional haemorrhoidectomy (COH) is still regarded as the gold standard treatment for non-circumferential grade II-IV haemorrhoids. Laser haemorrhoidoplasty (LAH) has recently been studied and the initial results appear promising. This study aims to compare these 2 techniques in the treatment of symptomatic haemorrhoids. We hypothesize that LAH has significantly less pain and bleeding and better quality of life (QoL) scores 1, 3 and 12 months post-operatively. METHODS: A prospective, randomized, double-blind, single-centre clinical trial will be conducted. All patients aged between 21 and 90 years who present with symptomatic grade II-IV haemorrhoids will be recruited. Exclusion criteria include those who have had previous operations for haemorrhoids and those with an increased risk of bleeding. Data collected will include patient demographics, pre- and intra-operative characteristics of the haemorrhoids, operative details and post-operative pain Visual Analogue Scale (VAS) score, complications, readmissions, and haemorrhoid-specific QoL surveys. Primary outcome will be median post-operative pain VAS score on post-operative days (POD) 1-10. Secondary outcomes include operative duration, bleeding on the first 10 days post-operatively, readmissions, procedure-related complications (fistulation, incontinence, stenosis), QoL scores, and recurrence of symptoms up to 12 months. DISCUSSION: Results from this trial may demonstrate the superiority of LAH over COH in terms of post-operative pain and recovery. This would likely increase the adoption of LAH for the treatment of symptomatic haemorrhoids. TRIAL REGISTRATION: This trial was registered on 1/4/2020 at ClinicalTrials.gov.

Analgesia efficacy of erector spinae plane block in laparoscopic abdominal surgeries: a systemic review and meta-analysis.

BACKGROUND: Multimodal analgesia is now widely practised to minimise postoperative opioid consumption while optimising pain control. The aim of this meta-analysis was to assess the analgesic efficacy of erector spinae plane block (ESPB) in patients undergoing laparoscopic abdominal surgeries. This will be determined by perioperative opioid consumption, subjective pain scores, and incidences of postoperative nausea and vomiting. METHODS: The authors systemically searched electronic databases for randomised controlled trials (RCTs) published up to February 2023 comparing ESPB with other adjuvant analgesic techniques in laparoscopic abdominal surgeries. Nine randomised controlled trials encompassing 666 subjects were included in our study. RESULTS: ESPB was shown to reduce postoperative opioid consumption [mean difference (MD) of -5.95 mg (95% CI: -8.86 to -3.04; P <0.0001); I2 =89%], intraoperative opioid consumption MD of -102.4 mcg (95% CI: -145.58 to -59.21; P <0.00001); I2 =39%, and incidence of nausea [RR 0.38 (95% CI: 0.25-0.60; P <0.0001); I2 =0%] and vomiting [RR 0.32 (95% CI: 0.17-0.63; P =0.0009); I2 =0%] in laparoscopic abdominal surgeries. Subgroup analysis on laparoscopic colorectal surgeries further showed reduction in postoperative pain scores MD of -0.68 (95% CI: -0.94 to -0.41); P <0.00001; I2 =0%]. CONCLUSIONS: This study concludes that ESPB is a valuable technique with proven efficacy to potentially promote faster postoperative recovery through optimising pain control while minimising opioid requirements.

Multimodal prerehabilitation for elderly patients with sarcopenia in colorectal surgery.

Sarcopenia, which is characterized by progressive and generalized loss of skeletal muscle mass and strength, has been well described to be associated with numerous poor postoperative outcomes, such as increased perioperative mortality, postoperative sepsis, prolonged length of stay, increased cost of care, decreased functional outcome, and poorer oncological outcomes in cancer surgery. Multimodal prehabilitation, as a concept that involves boosting and optimizing the preoperative condition of a patient prior to the upcoming stressors of a surgical procedure, has the purported benefits of reversing the effects of sarcopenia, shortening hospitalization, improving the rate of return to bowel activity, reducing the costs of hospitalization, and improving quality of life. This review aims to present the current literature surrounding the concept of sarcopenia, its implications pertaining to colorectal cancer and surgery, a summary of studied multimodal prehabilitation interventions, and potential future advances in the management of sarcopenia.

Structured presurgery prehabilitation for aged patients undergoing elective surgery significantly improves surgical outcomes and reduces cost: A nonrandomized sequential comparative prospective cohort study.

BACKGROUND: With increasing global life expectancy, the number of major surgeries performed on aged adults invariably increases. This study aimed to examine the effectiveness of a structured prehabilitative program for aged colorectal cancer patients in improving short-term surgical outcomes. METHODS: A prospective philanthropically sponsored Programme for Enhanced Elderly Recovery at Sengkang General Hospital (PEERS) was initiated in February 2017 for patients ≥70-years-old who were due to undergo elective colectomies. These patients were put through a 2- to 4-week-long program before surgery, which included geriatric assessment, nutrition supplementation, and resistance training. They were compared with patients from a similar age group before PEERS was introduced (non-PEERS). RESULTS: Fifty-eight patients, with a median age of 78.5 (70-93) years, were recruited from a single institution to undergo PEERS. Baseline characteristics between the groups were similar. There was no significant improvement of anthropometric and functional characteristics before and after PEERS. Duration of hospitalization was shorter in the PEERS group (9 vs 11 days, P = 0.01). Both groups had similar 30-days' morbidity rates (8.6% vs 17.4%, P = 0.26). The PEERS group had significant improvement in their median EuroQol-5 Dimension score (0.70 presurgery to 0.80 6-months' postsurgery, P = 0.01). After multivariate analysis, the average duration of hospitalization in the PEERS group was 6.8 days shorter (P = 0.018; CI, 1.2-12.4) after adjusting for modality of surgery and complications. This represented a cost saving of USD$11,838.80. CONCLUSION: A standardized prehabilitation program for aged adults reduced the duration of hospitalization, improved the quality of life after surgery, and reduced costs.

Paradigm shift in gastrointestinal surgery - combating sarcopenia with prehabilitation: Multimodal review of clinical and scientific data.

A growing body of evidence has demonstrated the prognostic significance of sarcopenia in surgical patients as an independent predictor of postoperative complications and outcomes. These included an increased risk of total complications, major complications, re-admissions, infections, severe infections, 30 d mortality, longer hospital stay and increased hospitalization expenditures. A program to enhance recovery after surgery was meant to address these complications; however, compliance to the program since its introduction has been less than ideal. Over the last decade, the concept of prehabilitation, or "pre-surgery rehabilitation", has been discussed. The presurgical period represents a window of opportunity to boost and optimize the health of an individual, providing a compensatory "buffer" for the imminent reduction in physiological reserve post-surgery. Initial results have been promising. We review the literature to critically review the utility of prehabilitation, not just in the clinical realm, but also in the scientific realm, with a resource management point-of-view.

Clinical outcome and cost comparison between laparoscopic and open appendicectomy.

INTRODUCTION: Local data comparing laparoscopic appendicectomy (LA) and open appendicectomy (OA) is lacking. We perform a cost and outcome comparison between LA and OA. MATERIALS AND METHODS: A retrospective review of all appendicectomies performed for suspected appendicitis from July 2010 to December 2010 was conducted. Patient demographics, duration of surgery, complication rates, total cost of stay (COS) and length of stay (LOS) were compared between LA and OA. RESULTS: A total of 198 patients underwent appendicectomy during the duration of study; 82 LA and 116 OA. There were 115 males (58.1%) and 83 females (41.9%). Median age was 33 years. Patients who underwent LA were significantly younger (P <0.001) with a greater proportion of females (P <0.0001) and were more likely to be negative appendicectomies (18.3% vs. 6.9%, P = 0.023). Duration of surgery was significantly longer in LA patients (86 min vs. 74 min, P = 0.003). LOS in the LA group was shorter by 1.3 days compared to OA (2.0 days vs. 3.3 days, P <0.0001). The differences in operative duration and LOS between LA and OA remained significant on multivariate analysis (P = 0.001 and P = 0.008, respectively). The COS (P = 0.359), wound infection rates (P = 0.528) and complication rates (P = 0.131) were not significantly different between the 2 groups. CONCLUSION: LA is associated with a shorter LOS while its cost is equivalent to OA. From the perspective of utilisation of healthcare resources, LA appears to be superior.

An audit study of the sensitivity and specificity of ultrasound, fine needle aspiration cytology and frozen section in the evaluation of thyroid malignancies in a tertiary institution.

INTRODUCTION: The aim of this study was to conduct an audit of the sensitivity and specificity of ultrasound, fi ne needle aspiration cytology (FNAC) and frozen section in the evaluation of thyroid malignancies in our practice. MATERIALS AND METHODS: The medical records of all the patients who underwent thyroid surgery in a tertiary institution's General Surgery Department between January 2005 and December 2007 were retrospectively reviewed using a standardised data collection template. Results of the ultrasounds, FNACs and frozen sections were compared with the fi nal histological diagnosis. RESULTS: A total of 112 patients underwent thyroid surgery in the 3-year study period. Thyroid malignancy constituted 34 (30%) of all patients who underwent thyroid surgery. The most popular diagnostic tools used were ultrasound (81%), FNAC (69%) and frozen section (59%). The sensitivity of ultrasound, FNAC and frozen section were 41.4%, 86.4% and 68.8%, respectively. FNAC was shown to be a superior diagnostic test in detecting malignancy compared to ultrasound. FNAC was able to pick up 53% of thyroid cancers missed by ultrasound. Frozen section was able to pick up 33% of thyroid cancers that were missed by both ultrasound and FNAC. CONCLUSION: FNAC is the most reliable tool in detecting malignancies and ought to form the mainstay for investigation of thyroid nodules. The utilisation of ultrasonographic features in the evaluation of thyroid nodules might not necessary improve the detection rate of thyroid malignancy. Frozen section helps to improve the detection rate of thyroid malignancy but further studies into its cost-effectiveness ought to be performed.
