Blockade of the mental nerve for lower lip surgery as a safe alternative to general anesthesia in two very old patients

Purpose: Regional anesthesia is gaining popularity with anesthesiologists as it offers superb postoperative analgesia. However, as the sole anesthetic technique in high-risk patients in whom general anesthesia is not preferred, some regional anesthetic possibilities may be easily overlooked. By presenting two cases of very old patients with considerable comorbidities, we would like to bring the mental nerve field block under renewed attention as a safe alternative to general anesthesia and to achieve broader application of this simple nerve block. Patients and methods: Two very old male patients(84 and 91 years) both presented with an ulcerative lesion at the lower lip for which surgical removal was scheduled. Because of their considerable comorbidities and increased frailty, bilateral blockade of the mental nerve was considered superior to general anesthesia. As an additional advantage for the 84-year-old patient, who had a pneumonectomy in his medical history, the procedure could be safely performed in a beach-chair position to prevent atelectasis and optimize the ventilation/perfusion ratio of the single lung. The mental nerve blockades were performed intraorally in a blind fashion, after eversion of the lip and identifying the lower canine. A 5 mL syringe with a 23-gauge needle attached was passed into the buccal mucosa until it approximated the mental foramen, where 2 mL of lidocaine 2% with adrenaline 1:100.000 was injected. The other side was anesthetized in a similar fashion. Results: Both patients underwent the surgical procedure uneventfully under a bilateral mental nerve block and were discharged from the hospital on the same day. Conclusion: A mental nerve block is an easy-to-perform regional anesthetic technique for lower lip surgery. This technique might be especially advantageous in the very old, frail patient

Textbook Outcome Nationwide Analysis of a Novel Quality Measure in Pancreatic Surgery:Nationwide Analysis of a Novel Quality Measure in Pancreatic Surgery

Background: Textbook outcome (TO) is a multidimensional measure for quality assurance, reflecting the ‘‘ideal’’ surgical outcome. Methods: Post-hoc analysis of patients who underwent pancreatoduodenectomy (PD) or distal pancreatectomy (DP) for all indications between 2014 and 2017, queried from the nationwide prospective Dutch Pancreatic Cancer Audit. An international survey was conducted among 24 experts from 10 countries to reach consensus on the requirements for TO in pancreatic surgery. Univariable and multivariable logistic regression was performed to identify TO predictors. Between-hospital variation in TO rates was compared using observed-versus-expected rates. Results: Based on the survey (92% response rate), TO was defined by the absence of postoperative pancreatic fistula, bile leak, postpancreatectomy hemorrhage (all ISGPS grade B/C), severe complications (Clavien–Dindo III), readmission, and in-hospital mortality. Overall, 3341 patients were included (2633 (79%) PD and 708 (21%) DP) of whom 60.3% achieved TO; 58.3% for PD and 67.4% for DP. On multivariable analysis, ASA class 3 predicted a worse TO rate after PD (ASA 3 OR 0.59 [0.44–0.80]), whereas a dilated pancreatic duct (>3 mm) and pancreatic ductal ade

Impact of complications after resection of pancreatic cancer on disease recurrence and survival, and mediation effect of adjuvant chemotherapy:nationwide, observational cohort study

Background: The causal pathway between complications after pancreatic cancer resection and impaired long-term survival remains unknown. The aim of this study was to investigate the impact of complications after pancreatic cancer resection on disease-free interval and overall survival, with adjuvant chemotherapy as a mediator.Methods: This observational study included all patients undergoing pancreatic cancer resection in the Netherlands (2014-2017). Clinical data were extracted from the prospective Dutch Pancreatic Cancer Audit. Recurrence and survival data were collected additionally. In causal mediation analysis, direct and indirect effect estimates via adjuvant chemotherapy were calculated.Results: In total, 1071 patients were included. Major complications (hazards ratio 1.22 (95 per cent c.i. 1.04 to 1.43); P = 0.015 and hazards ratio 1.25 (95 per cent c.i. 1.08 to 1.46); P = 0.003) and organ failure (hazards ratio 1.86 (95 per cent c.i. 1.32 to 2.62); P &lt; 0.001 and hazards ratio 1.89 (95 per cent c.i. 1.36 to 2.63); P &lt; 0.001) were associated with shorter disease-free interval and overall survival respectively. The effects of major complications and organ failure on disease-free interval (-1.71 (95 per cent c.i. -2.27 to -1.05) and -3.05 (95 per cent c.i. -4.03 to -1.80) respectively) and overall survival (-1.92 (95 per cent c.i. -2.60 to -1.16) and -3.49 (95 per cent c.i. -4.84 to -2.03) respectively) were mediated by adjuvant chemotherapy. Additionally, organ failure directly affected disease-free interval (-5.38 (95 per cent c.i. -9.27 to -1.94)) and overall survival (-6.32 (95 per cent c.i. -10.43 to -1.99)). In subgroup analyses, the association was found in patients undergoing pancreaticoduodenectomy, but not in patients undergoing distal pancreatectomy.Conclusion: Major complications, including organ failure, negatively impact survival in patients after pancreatic cancer resection, largely mediated by adjuvant chemotherapy. Prevention or adequate treatment of complications and use of neoadjuvant treatment may improve oncological outcomes.</p

Impact of Complications After Pancreatoduodenectomy on Mortality, Organ Failure, Hospital Stay, and Readmission Analysis of a Nationwide Audit:Analysis of a Nationwide Audit

OBJECTIVE: To quantify the impact of individual complications on mortality, organ failure, hospital stay, and readmission after pancreatoduodenectomy. SUMMARY OF BACKGROUND DATA: An initial complication may provoke a sequence of adverse events potentially leading to mortality after pancreatoduodenectomy. This study was conducted to aid prioritization of quality improvement initiatives. METHODS: Data from consecutive patients undergoing pancreatoduodenectomy (2014-2017) were extracted from the Dutch Pancreatic Cancer Audit. Population attributable fractions (PAF) were calculated for the association of each complication (ie, postoperative pancreatic fistula, postpancreatectomy hemorrhage, bile leakage, delayed gastric emptying, wound infection, and pneumonia) with each unfavorable outcome [ie, in-hospital mortality, organ failure, prolonged hospital stay (>75th percentile), and unplanned readmission), whereas adjusting for confounders and other complications. The PAF represents the proportion of an outcome that could be prevented if a complication would be eliminated completely. RESULTS: Overall, 2620 patients were analyzed. In-hospital mortality occurred in 95 patients (3.6%), organ failure in 198 patients (7.6%), and readmission in 427 patients (16.2%). Postoperative pancreatic fistula and postpancreatectomy hemorrhage had the greatest independent impact on mortality [PAF 25.7% (95% CI 13.4-37.9) and 32.8% (21.9-43.8), respectively] and organ failure [PAF 21.8% (95% CI 12.9-30.6) and 22.1% (15.0-29.1), respectively]. Delayed gastric emptying had the greatest independent impact on prolonged hospital stay [PAF 27.6% (95% CI 23.5-31.8)]. The impact of individual complications on unplanned readmission was smaller than 11%. CONCLUSION: Interventions focusing on postoperative pancreatic fistula and postpancreatectomy hemorrhage may have the greatest impact on in-hospital mortality and organ failure. To prevent prolonged hospital stay, initiatives should in addition focus on delayed gastric emptying

Care after pancreatic resection according to an algorithm for early detection and minimally invasive management of pancreatic fistula versus current practice (PORSCH-trial):design and rationale of a nationwide stepped-wedge cluster-randomized trial

Background: Pancreatic resection is a major abdominal operation with 50% risk of postoperative complications. A common complication is pancreatic fistula, which may have severe clinical consequences such as postoperative bleeding, organ failure and death. The objective of this study is to investigate whether implementation of an algorithm for early detection and minimally invasive management of pancreatic fistula may improve outcomes after pancreatic resection. Methods: This is a nationwide stepped-wedge, cluster-randomized, superiority trial, designed in adherence to the Consolidated Standards of Reporting Trials (CONSORT) guidelines. During a period of 22 months, all Dutch centers performing pancreatic surgery will cross over in a randomized order from current practice to best practice according to the algorithm. This evidence-based and consensus-based algorithm will provide daily multilevel advice on the management of patients after pancreatic resection (i.e. indication for abdominal imaging, antibiotic treatment, percutaneous drainage and removal of abdominal drains). The algorithm is designed to aid early detection and minimally invasive step-up management of postoperative pancreatic fistula. Outcomes of current practice will be compared with outcomes after implementation of the algorithm. The primary outcome is a composite of major complications (i.e. post-pancreatectomy bleeding, new-onset organ failure and death) and will be measured in a sample size of at least 1600 patients undergoing pancreatic resection. Secondary endpoints include the individual components of the primary endpoint and other clinical outcomes, healthcare resource utilization and costs analysis. Follow up will be up to 90 days after pancreatic resection. Discussion: It is hypothesized that a structured nationwide implementation of a dedicated algorithm for early detection and minimally invasive step-up management of postoperative pancreatic fistula will reduce the risk of major complications and death after pancreatic resection, as compared to current practice. Trial registration: Netherlands Trial Register: NL 6671. Registered on 16 December 2017

The Effect of a Temporary Stoma on Long-term Functional Outcomes Following Surgery for Rectal Cancer

BACKGROUND: Patients with rectal cancer may undergo surgical resection with or without a temporary stoma.OBJECTIVE: This study primarily aimed to compare long-term functional outcomes between patients with and without a temporary stoma after surgery for rectal cancer. The secondary aim was to investigate the effect of time to stoma reversal on functional outcomes.DESIGN: This was a multicenter, cross-sectional study.SETTINGS: This study was conducted at 7 Dutch hospitals. PATIENTS: Included were patients who had undergone rectal cancer surgery (2009–2015). Excluded were deceased patients, who were deceased, had a permanent stoma, or had intellectual disability. MAIN OUTCOME MEASURES: Functional outcomes were measured using the Rome IV criteria for constipation and fecal incontinence and the low anterior resection syndrome score. RESULTS: Of 656 patients, 32% received a temporary ileostomy and 20% a temporary colostomy (86% response). Follow-up was at 56 (interquartile range, 38.5–79) months. Patients who had a temporary ileostomy experienced less constipation, more fecal incontinence, and more major low anterior resection syndrome than those without a temporary stoma. Patients who had a temporary colostomy experienced more major low anterior resection syndrome than those without a temporary stoma. A temporary ileostomy or colostomy was not associated with constipation or fecal incontinence after correction for confounding factors (eg, anastomotic height, anastomotic leakage, radiotherapy). Time to stoma reversal was not associated with constipation, fecal incontinence, or major low anterior resection syndrome. LIMITATIONS: Cross-sectional design. CONCLUSIONS: Although patients with a temporary ileostomy or colostomy have worse functional outcomes in the long term, it seems that the reason for creating a temporary stoma, rather than the stoma itself, underlies this phenomenon. Time to reversal of a temporary stoma does not influence functional outcomes.BACKGROUND: Patients with rectal cancer may undergo surgical resection with or without a temporary stoma.

Anastomotic Height is a Valuable Indicator of Long-term Bowel Function Following Surgery for Rectal Cancer

BACKGROUND: The exact relation between anastomotic height after rectal cancer surgery and postoperative bowel function problems has not been investigated in the long term, causing ineffective treatment.OBJECTIVE: To determine the effect of anastomotic height on long-term bowel function and generic quality of life.DESIGN: A multicenter cross-sectional study.SETTINGS: Seven Dutch hospitals in the north of the Netherlands participated.PATIENTS: All patients who underwent rectal cancer surgery between 2009 and 2015 in the participating hospitals received the validated Defecation and Fecal Continence and Short-Form 36 questionnaires. Deceased patients, patients with a permanent stoma or an anastomosis &gt;15 cm from the anal verge, intellectual disability, or living abroad were excluded.MAIN OUTCOME MEASURES: Primary outcomes were constipation (Rome IV), fecal incontinence (Rome IV), and major low anterior resection syndrome. Secondary outcomes were the generic quality of life scores.RESULTS: The study population (N=630) had a median follow-up of 58.0 months. In multivariable analysis, constipation (OR = 1.08, 95% CI, 1.02-1.15, p = 0.011), fecal incontinence (OR = 0.91, 95% CI, 0.84-0.97, p = 0.006), and major low anterior resection syndrome (OR = 0.93, 95% CI, 0.87-0.99, p = 0.027), were significantly associated with anastomotic height. The curves illustrating the probability of constipation and fecal incontinence crossed at an anastomotic height of 7 cm, with 95% CIs overlapping between 4.5-9.5 cm. There was no relation between quality of life scores and anastomotic height.LIMITATIONS: The study is limited by its cross-sectional design.CONCLUSIONS: This study might serve as a guide for the clinician to effectively screen and treat fecal incontinence and constipation during the follow-up of patients after rectal cancer surgery. More attention should be paid to fecal incontinence in patients with an anastomosis below 4.5 cm and towards constipation in patients with an anastomosis above 9.5 cm.

Long-term Bowel Dysfunction and Decline in Quality of Life Following Surgery for Colon Cancer: Call for Personalized Screening and Treatment

BACKGROUND: Differences in long-term outcomes regarding types of colon resections are inconclusive, precluding preoperative patient counseling and effective screening and personalized treatment of postoperative bowel dysfunction during follow-up. OBJECTIVE: To compare long-term bowel function and quality of life in patients who underwent right or left hemicolectomy, or sigmoid colon resection. DESIGN: A multicenter cross-sectional study. SETTINGS: Seven Dutch hospitals participated. PATIENTS: Included patients underwent right or left hemicolectomy, or sigmoid colon resection without construction of a permanent stoma between 2009 and 2015. Deceased, mentally impaired, or patients living abroad were excluded. Eligible patients were sent the validated Defecation and Fecal Continence and Short-Form 36 questionnaires. MAIN OUTCOME MEASURES: Constipation, fecal incontinence (both Rome IV criteria), separate bowel symptoms, and generic quality of life were assessed. RESULTS: Included were 673 right hemicolectomy, 167 left hemicolectomy, and 284 sigmoid colon resection patients. Median follow-up was 56 months (IQR 41-80). Sigmoid colon resection increased the likelihood of constipation compared to right and left hemicolectomy (OR, 2.92, 95% CI, 1.80-4.75, p < 0.001 and OR 1.93, 95% CI, 1.12-3.35, p = 0.019). Liquid incontinence and fecal urgency increased following right hemicolectomy compared to sigmoid colon resection (OR, 2.15, 95% CI, 1.47-3.16, p < 0.001 and OR 2.01, 95% CI, 1.47-2.74, p < 0.001). Scores on quality of life domains were significantly lower following right hemicolectomy. LIMITATIONS: Due to the cross-sectional design, longitudinal data are still lacking. CONCLUSIONS: Different long-term bowel function problems occur following right or left hemicolectomy, or sigmoid colon resection. The latter seems to be associated with more constipation than right or left hemicolectomy. Liquid incontinence and fecal urgency seem to be associated with right hemicolectomy, which may explain the decline in physical and mental generic quality of life of these patients.
