For elective surgery of colorectal cancer, current evidence supports preoperative mechanical bowel preparation combined with oral antibiotics. Meanwhile, for patients with varied degrees of intestinal stenosis, individualized protocol is required to avoid adverse events. We hereby summarize recent high-quality evidences and updates of guidelines and consensus, and recommend stratified bowel preparation based on the clinical practice of our institute as follows. (1) For patients with unimpaired oral intake, whose tumor can be passed by colonoscopy, mechanical bowel preparation and oral antibiotics are given. (2) For patients without symptoms of bowel obstruction but with impaired oral intake or incomplete colonoscopy due to tumor-related stenosis, small-dosage laxative is given for several days before surgery, and oral antibiotics the day before surgery. (3) For patients with bowel obstruction, mechanical bowel preparation or enema is not indicated. We proposed this evidence-based, individualized protocol for preoperative bowel preparation for the reference of our colleagues, in the hope of improving perioperative outcomes and reducing adverse events.

The COVID-19 pandemic has had a major impact in healthcare systems across the world, with many hospitals having to come up with protocols and measures to contain the spread of the virus. This affects various specialties' clinical practices in many ways. Since early 2020 in Singapore, the Department of Otorhinolaryngology at Tan Tock Seng Hospital had to rapidly adapt to this pandemic as we provided services to the main healthcare facility combating the virus in our country. We had to design new workflows and also remain flexible in view of the ever-changing situation. There are 6 important domains for an otolaryngology department or any clinical department in general to consider when making adjustments to their practices in an outbreak: (1) clinical work, (2) education, (3) research, (4) safety of patients and staff, (5) morale of medical staff and (6) pandemic frontline work. We hope that the sharing of our experiences and the lessons learnt will be useful for both our local and international colleagues.

5.Production pressures among anaesthesiologists in Singapore.
Jia Xin CHAI ; Shin Yuet CHONG
Singapore medical journal 2018;59(5):271-278
INTRODUCTIONProduction pressure is the pressure on personnel to prioritise production ahead of safety. We assessed the prevalence of production pressures among anaesthesiologists in Singapore.
METHODSA random online survey was conducted among local anaesthesiologists. Questions were asked about attitudes to production pressures in the work environment, occurrence of situations involving unsafe actions, and rating of the intensity of external and internal sources of pressure.
RESULTSDemographically, our respondents were largely similar to all anaesthesiologists in Singapore and were fairly distributed across various tertiary hospitals. Nearly half (44.5%) had witnessed production pressures, with a colleague pressured to conduct anaesthesia in an unsafe manner. Such events included pressure from surgeons to proceed for elective surgery in patients without adequate optimisation, pressure to employ anaesthetic techniques that surgeons wanted, having to source for operating rooms to finish the surgeon's list, and being misled regarding surgical time. Over half (52.3%) made errors in clinical judgement due to excess workload. A heavy elective list workload was significantly associated with proceeding with patients despite lack of appropriate support, making changes to practices to avoid delaying the start of surgery and sourcing for operating rooms to finish the surgeon's list (p < 0.05), and being pressured to proceed with patients that the anaesthesiologist would otherwise have cancelled (p < 0.01). The need to avoid delaying the start of surgery and reduce turnover time between patients were the top-ranked internal and external pressures, respectively.
CONCLUSIONProduction pressure is prevalent among anaesthesiologists in Singapore and is correlated with a heavy workload.

BACKGROUNDAirway management is critical in patients with cervical spondylosis, a population with a high incidence of difficult airway. Intubation with Shikani Optical Stylet (SOS) has become increasingly popular in difficult airway. We compared the effects of intubation with SOS versus Macintosh laryngoscope (MLS) in patients undergoing surgery for cervical spondylosis.
METHODSA total of 270 patients scheduled for elective surgery for cervical spondylosis of spinal cord and nerve root type from August 2012 to January 2016 were enrolled and randomly allocated to the MLS or SOS group by random numbers. Patients were evaluated for difficult airway preoperatively, and Cormack-Lehane laryngoscopy classification was determined during anesthesia induction. Difficult airway was defined as Cormack-Lehane Grades III-IV. Patients were intubated with the randomly assigned intubation device. The success rate, intubation time, required assistance, immediate complications, and postoperative complaints were recorded. Categorical variables were analyzed by Chi-square test, and continuous variables were analyzed by independent samples t-test or rank sum test.
RESULTSThe success rate of intubation among normal airways was 100% in both groups. In patients with difficult airway, the success rates in the MLS and SOS groups were 84.2% and 94.1%, respectively (P = 0.605). Intubation with SOS took longer compared with MLS (normal airway: 25.1 ± 5.8 s vs. 24.5 ± 5.7 s, P = 0.426; difficult airway: 38.5 ± 8.5 s vs. 36.1 ± 8.2 s, P = 0.389). Intubation with SOS required less assistance in patients with difficult airway (5.9% vs. 100%, P< 0.001). The frequency of postoperative sore throat was lower in SOS group versus MLS group in patients with normal airway (22.0% vs. 34.5%, P = 0.034).
CONCLUSIONSSOS is a safe and effective airway management device in patients undergoing surgery for cervical spondylosis. Compared with MLS, SOS appears clinically beneficial for intubation, especially in patients with difficult airway.

BACKGROUNDEnhanced recovery after surgery (ERAS) protocols or fast-track (FT) programs enable a shorter hospital stay and lower complication rate. Minimally invasive surgery (MIS) is associated with a lesser trauma and a quicker recovery in many elective abdominal surgeries. However, little is known of the safety and effectiveness made by ERAS protocols combined with MIS for gastric cancer. The purpose of this study was to evaluate the safety and effectiveness made by FT programs and MIS in combination or alone.
METHODSWe summarized an 11-year experience on gastric cancer patients undergoing elective laparotomy or minimally invasive gastric resection in standard cares (SC) or FT programs during January 2004 to December 2014. A total of 984 patients were enrolled and assigned into four groups: open gastrectomies (OG) with SC (OG + SC group, n = 167); OG with FT programs (OG + FT group, n = 277); laparoscopic gastrectomies (LG) with FT programs (LG + FT group, n = 248); and robot-assisted gastrectomies (RG) with FT programs (RG + FT group, n = 292). Patients' data were collected to evaluate the clinical outcome. The primary end point was the length of postoperative hospital stay.
RESULTSThe OG + SC group showed the longest postoperative hospital stay (mean: 12.3 days, median: 11 days, interquartile range [IQR]: 6-16 days), while OG + FT, LG + FT, and RG + FT groups recovered faster (mean: 7.4, 6.4, and 6.6 days, median: 6, 6, and 6 days, IQR: 3-9, 4-8, and 3-9 days, respectively, all P< 0.001). The postoperative rehabilitation parameters such as flatus time after surgery (4.7 ± 0.9, 3.1 ± 0.8, 3.0 ± 0.9, and 3.1 ± 0.9 days) followed the same manner. After 30 postoperative days' follow-up, the total incidence of complications was 9.6% in OG + SC group, 10.1% in OG + FT group, 8.1% in LG + FT group, and 10.3% in RG + FT group. The complications showed no significant differences between the four groups (all P > 0.05).
CONCLUSIONSERAS protocols alone could significantly bring fast recovery after surgery regardless of the surgical technique. MIS further reduces postoperative hospital stay. It is safe and effective to apply ERAS protocols combined with MIS for gastric cancer.

INTRODUCTIONThe prevalence of hiatal hernias and para-oesophageal hernias (PEHs) is lower in Asian populations than in Western populations. Progressive herniation can result in giant PEHs, which are associated with significant morbidity. This article presents the experience of an Asian acute care tertiary hospital in the management of giant PEH and parahiatal hernia.
METHODSSurgical records dated between January 2003 and January 2013 from the Department of Surgery, Changi General Hospital, Singapore, were retrospectively reviewed.
RESULTSTen patients underwent surgical repair for giant PEH or parahiatal hernia during the study period. Open surgery was performed for four patients with giant PEH who presented emergently, while elective laparoscopic repair was performed for six patients with either giant PEH or parahiatal hernia (which were preoperatively diagnosed as PEH). Anterior 180° partial fundoplication was performed in eight patients, and mesh reinforcement was used in six patients. The electively repaired patients had minimal or no symptoms during presentation. Gastric volvulus was observed in five patients. There were no cases of mortality. The median follow-up duration was 16.3 months. There were no cases of mesh erosion, complaints of dysphagia or recurrence of PEH in all patients.
CONCLUSIONGiant PEH and parahiatal hernia are underdiagnosed in Asia. Most patients with giant PEH or parahiatal hernia are asymptomatic; they often present emergently or are incidentally diagnosed. Although surgical outcomes are favourable even with a delayed diagnosis, there should be greater emphasis on early diagnosis and elective repair of these hernias.

Objective To compare the Ambu Aura-i with the Air-Q intubating laryngeal airway for fiberoptic-guided tracheal intubation in ear deformity children.Methods Totally 120 children who were scheduled for elective auricular reconstruction surgery requiring general anaesthesia with tracheal intubation were enrolled in this prospective study. They were randomized to receive either the Ambu Aura-i (Aura-i group) or Air-Q (Air-Q group). The time for successful tracheal intubation was assessed. The attempts for successful device insertion, leak pressures, cuff pressures, fiberoptic grade of laryngeal view, time for removal of the device after endotracheal intubation, and complications were recorded. Results Device placement, endotracheal intubation, and removal after endotracheal intubation were successful in all patients. The Air-Q group required longer time than the Aura-i group in device placement[(14.1±7.2) s vs. (10.8±5.2) s, P<0.05], successful endotracheal intubation [(39.8±9.5) s vs. (24.1±8.2) s, P<0.05], and device removal [(18.2±5.1) s vs. (14.7±3.7) s, P<0.05]. There were no differences in fiberoptic grade of view between these devices, and the percentage of glottis seen was 80.0% (Air-Q group) vs. 86.7% (Aura-i group). The leak pressure was (20.5±4.8) cmHO in the Air-Q group and (22.2±5.0) cmHO in the Aura-i group (P<0.05), and the cuff pressure was (22.9±11.5)cmHO in the Air-Q group and (33.9±15.9) cmHO in the Aura-i group (P<0.05). Hemodynamic changes were not significantly different between two group. The incidence rate of sore throat two hours after operation was 6.5% (n=4) in the Air-Q group and 5% (n=3) in the Aura-i group. Conclusion Both Ambu Aura-i and Air-Q intubating laryngeal airway are effective conduits for beroptic-guided tracheal intubation, with advantages including simple operation, high success rate, and fewer complications, especially the Ambu Aura-i.

PURPOSE: Cholecystectomy in patients with an intact gallbladder after endoscopic removal of stones from the common bile duct (CBD) remains controversial. We conducted a case-control study to determine the risk of recurrent CBD stones and the benefit of cholecystectomy for prevention of recurrence after endoscopic removal of stones from the CBD in Korean patients. MATERIALS AND METHODS: A total of 317 patients who underwent endoscopic CBD stone extraction between 2006 and 2012 were included. Possible risk factors for the recurrence of CBD stones including previous cholecystectomy history, bile duct diameter, stone size, number of stones, stone composition, and the presence of a periampullary diverticulum were analyzed. RESULTS: The mean duration of follow-up after CBD stone extraction was 25.4+/-22.0 months. A CBD diameter of 15 mm or larger [odds ratio (OR), 1.930; 95% confidence interval (CI), 1.098 to 3.391; p=0.022] and the presence of a periampullary diverticulum (OR, 1.859; 95% CI, 1.014 to 3.408; p=0.045) were independent predictive factors for CBD stone recurrence. Seventeen patients (26.6%) in the recurrence group underwent elective cholecystectomy soon after endoscopic extraction of CBD stones, compared to 88 (34.8%) in the non-recurrence group; the difference was not statistically significant (p=0.212). CONCLUSION: A CBD diameter of 15 mm or larger and the presence of a periampullary diverticulum were found to be potential predictive factors for recurrence after endoscopic extraction of CBD stones. Elective cholecystectomy after clearance of CBD stones did not reduce the incidence of recurrent CBD stones in Korean patients.
