Routine use of feeding jejunostomy in oesophageal cancer resections: results of a survey in England

Nutrition and post-operative feeding in oesophageal cancer resections for enhanced recovery remain a controversial subject. Feeding jejunostomy tubes (FJT) have been used post-operatively to address the subject but evidence to support its routine use is contentious. There is currently no data on FJT use in England for oesophageal cancer resections. Knowledge regarding current FJT usage, and rationale for its use may provide a snapshot of the trend and current standing on FJT use by resectional units in England. A standardised survey was sent electronically to all oesophageal resectional units in the United Kingdom (UK) between October 2016 and January 2018. In summary, the questionnaire probes into current FJT use, rationale for its usage, consideration of cessation of its use, and rationale of cessation of its use for units not using FJT. The resectional units were identified using the National Oesophago-Gastric Cancer Audit (NOGCA) progress report 2016 and 1 selected resectional unit from Northern Ireland, Scotland, and Wales, respectively. Performance data of those units were collected from the 2017 NOGCA report. Out of 40 units that were eligible, 32 (80.0%) centres responded. The responses show a heterogeneity of FJT use across the resectional centres. Most centres (56.3%) still place FJT routinely with 2 of 18 (11.1%) were considering stopping its routine use. FJT was considered a mandatory adjunct to chemotherapy in 3 (9.4%) centres. FJT was not routinely used in 9 (28.1%) of centres with 5 of 9 (55.6%) reported previous complications and 4 of 9 (44.4%) cited using other forms of nutrition supplementation as factors for discontinuing FJT use. There were 5 (15.6%) centres with divided practice among its consultants. Of those 2 of 5 (40.0%) were considering stopping FJT use, and hence, a total of 4 of 23 (17.4%) of units are now considering stopping routine FJT use. In conclusion, the wider practice of FJT use in the UK remains heterogenous. More research regarding the optimal post-operative feeding regimen needs to be undertaken.

Intraoperative pyloric botulinum toxin injection during Ivor-Lewis gastroesophagectomy to prevent delayed gastric emptying

Delayed gastric emptying (DGE) is a common morbidity that affects 10%-50% of Ivor-Lewis gastroesophagectomy (ILGO) patients. DGE management is variable with no gold standard prevention or treatment. We conducted a study to assess the effectiveness of intraoperative pyloric botulinum toxin injection in preventing DGE. All patients undergoing an ILGO for curative intent, semi-mechanical anastomosis, and enhanced recovery between 1st December 2011 and 30th June 2017 were included. Patients with pyloroplasties were excluded and botulinum toxin was routinely given from the 2nd April 2016. We compared botulinum toxin injection (BOTOX) against no intervention (NONE) for patient demographics, adjuvant therapy, surgical approach, DGE incidence, length of stay (LOS), and complications. Additionally, we compared pneumonia risk, anastomotic leak rate, and LOS in DGE versus non-DGE patients. DGE was defined using nasogastric tube input/output differences and chest X-ray appearance according to an algorithm adopted in our unit, which were retrospectively applied. There were 228 patients: 65 (28.5%) received botulinum toxin and 163 (71.5%) received no intervention. One hundred twenty-four (54.4%) operations were performed laparoscopically, of which 11 (4.8%) were converted to open procedures, and 104 (45.6%) were open operations. DGE incidence was 11 (16.9%) in BOTOX and 29 (17.8%) in NONE, P = 0.13. Medical management was required in 14 of 228 (6.1%) cases: 3 (4.6%) in BOTOX and 11 (4.8%) in NONE. Pyloric dilatation was required in 26 of 228 (11.4%): 8 of 65 (12.3%) in the BOTOX and 18 of 163 (11.0%) in NONE. There were no significant differences between groups and requirement for intervention, P = 0.881. Overall median LOS was 10 (6.0-75.0) days: 9 (7.0-75.0) in BOTOX and 10 (6.0-70.0) in NONE, P = 0.516. In non-DGE versus DGE patients, median LOS was 9 (6-57) versus 14 (7-75) days (P < 0.0001), pneumonia incidence of 27.7% versus 30.0% (P = 0.478), and anastomotic leak rate of 2.1% versus 10.0% (P = 0.014). Overall leak rate was 3.5%. Overall complication rate was 67.1%, including minor/mild complications. There were 43 of 65 (66.2%) in BOTOX and 110 of 163 (67.5%) in NONE, P = 0.482. In-hospital mortality was 1 (0.44%), 30-day mortality was 2 (0.88%), 90-day mortality was 5 (2.2%), and there were no 30-day readmissions. Intraoperative pyloric botulinum toxin injections were ineffective in preventing DGE (BOTOX vs. NONE: 16.9% vs. 17.8%) or reducing postoperative complications. DGE was relatively common (17.5%) with 11.4% of patients requiring postoperative balloon dilatation. DGE also resulted in prolonged LOS (increase from 9 to 14 days) and significant increase in leak rate from 2.1% to 10.0%. A better understanding of DGE will guide assessment, investigation, and management of the condition.

Need for standardization of the measurement of preoperative weight in bariatric surgical patients in the UK: A survey of British Obesity and Metabolic Surgery Society (BOMSS) members

BACKGROUND

Weight loss is the most commonly used metric in comparing outcomes after bariatric surgery. This is frequently presented in the form of percentage of excess weight loss (%EWL). Patients' weight is measured at several time points prior to surgery. The time point selected as the preoperative weight can have significant effects upon the measurement of %EWL. This study aimed to investigate whether there was any standardization in the selection of preoperative weight amongst UK bariatric surgery healthcare professionals.

METHODS

A questionnaire survey was conducted among the delegates at the British Obesity and Metabolic Surgery Society (BOMSS) meeting in January 2011.

RESULTS

A total of 54 delegates (consultant & trainee surgeons, bariatric specialist nurses, dieticians and psychologists) responded to the survey. A wide variation was noted in which preoperative weight was used in the calculation of %EWL, both among various disciplines and also among the same disciplines. The majority (61%) used the preoperative weight recorded at the bariatric surgical assessment clinic prior to surgery. 20% of delegates used the highest recorded preoperative weight. The remainder of delegates used weight recorded on the day of surgery (17%) or the weight recorded during the first visit to a medical physician led weight management clinic (2%).

CONCLUSION

Variation in the measurement of the preoperative weight will lead to variations of calculated %EWL between different bariatric units or even between different disciplines in the same unit. This will make comparison of published outcome data difficult. This study highlights the urgent need for standardization.

Establishing an Outpatient Clinic for Minimally Invasive Vein Care

OBJECTIVE

Minimally invasive vein care procedures are less invasive than surgery and have a lower complication rate, are well tolerated by patients, and have good cosmetic results. Because radiologists have expertise in imaging-guided procedures, offering minimally invasive vein care is a logical step.

CONCLUSION

Starting an effective outpatient vein care clinic involves decisions about space, equipment, and advertising. With proper staffing and rapport with patients and referring physicians, a varicose vein practice can be a profitable adjunct to any radiology practice.

Sacculo-collic response in otosclerosis and following successful stapes surgery

Introduction:

The sacculo-collic reflex is believed to be a short latency, otolith-mediated myogenic response to sound. With the application of air-conducted sound, one would expect an absent response in stapes fixation, as a fixed stapes footplate will not transmit a pressure wave to the saccule.

Methods:

Fifty patients (70 stapes surgery ears, 26 otosclerotic ears and four normal ears) and 40 controls underwent repeated sacculo-collic tests.

Results:

The results support the proposed mechanism for the sacculo-collic response. The study also suggests that, whilst stapedotomy piston prostheses are effective in the reversal of conductive hearing loss, they produce an insufficient pressure wave to elicit a myogenic response to sound.

Conclusion:

The sacculo-collic test could be a useful tool for screening otolith function and inferior vestibular nerve integrity, but further work is needed to determine the effect of stapes surgery on saccular function.

Fracture and Migration of a Suprarenal Inferior Vena Cava Filter in a Pregnant Patient

Placement of retrievable inferior vena cava (IVC) filters as prophylaxis for pulmonary embolism (PE) is an increasingly attractive option for patients who require temporary IVC filtration. However, experience thus far with retrievable filters in pregnant patients is limited. This report describes a suprarenally placed Recovery IVC filter in a pregnant woman with PE despite therapeutic anticoagulation. After failed induction of labor and uneventful cesarean section, the patient returned for filter retrieval 167 days after initial placement. Fracture and inferior migration of the filter was observed, and subsequent attempts at filter retrieval were unsuccessful.

Restoration of Patency in Failing Tunneled Hemodialysis Catheters: A Comparison of Catheter Exchange, Exchange and Balloon Disruption of the Fibrin Sheath, and Femoral Stripping

PURPOSE

To compare median patency times after treatment of malfunctioning tunneled hemodialysis catheters by one of three techniques: over-the-wire catheter exchange (CE), fibrin sheath stripping (FSS) from a femoral vein approach, and over-the-wire catheter removal with balloon dilation of fibrin sheath (DFS) followed by catheter replacement with use of the same tract.

MATERIALS AND METHODS

Retrospective study was conducted of 66 consecutive procedures performed over a period of 47 months for poor flow through tunneled hemodialysis catheters despite tissue plasminogen activator infusion trials (CE, n=33; FSS, n=18; DFS, n=15). Baseline parameters (time since initial catheter placement, number of previous catheter interventions, catheter access site, and patient age and sex) were recorded to identify possible pretreatment differences among groups. Outcome comparison was based on duration of adequate catheter function on dialysis during follow-up.

RESULTS

No significant differences in baseline parameters were identified among the three groups (P>.05). Mean follow-up duration (67+/-89 days; range, 0-398 d) was similar among the three groups. The immediate technical success rate was 100%, and there were no complications. Cumulative catheter patency rates were 73% (CE), 72% (FSS), and 65% (DFS) at 1 month; 43% (CE), 60% (FSS), and 39% (DFS) at 3 months; and 28% (CE), 45% (FSS), and 39% (DFS) at 6 months. Median duration of patency was similar among groups (P=.60).

CONCLUSIONS

All three therapies were equivalent in terms of immediate technical success, complication rates, and durability of catheter function during later follow-up. Hence, when one technique is chosen over another, factors other than the period of secondary patency should be considered, such as cost and patient and physician preference.
