The modified 'Jo'burg' technique for securing intercostal chest drains.

Insertion of an intercostal chest drain (ICD) is a common intervention in the management of either blunt or penetrating thoracic trauma. It is frequently performed by junior medical personnel as an emergency procedure during the initial resuscitation period and often within a stressful environment. Approximately one-fifth of all ICD insertions are associated with complications. In a retrospective review of over 1000 ICD insertions, 7% of the complications observed were due to inadequate fixation, resulting in dislodgement. The risk of dislodgement is greatest during transit or transfer of a casualty. In a military setting, this may involve movement of a casualty in a non-permissive environment and includes transfer on and off rotary wing, fixed wing, road vehicle and maritime transport platforms as well as between stretchers and hospital beds. While ICD insertion follows a standard technique in accordance with the Advanced Trauma Life Support guidelines, the method of securing ICDs has not been standardised across the Defence Medical Services (DMS). The aim of this paper is to first propose a modified version of a tried and tested technique of securing ICDs with alternative steps described for medical staff unfamiliar with surgical knot tying by hand. Second, we present the results from a pilot validation study of this technique when introduced to candidates on a trauma surgical skills course. We describe and demonstrate a robust, easily teachable and reproducible technique for securing ICDs. We would advocate the use of this technique among both surgically and non-surgically trained medical personnel and suggest that this should become the standardised technique for securing ICDs across the DMS. This could be easily implemented by introducing this technique into the various military trauma courses, for example the Military Operational Surgical Training, Medical Emergency Response Team and Critical Care Air Support Team courses.

Maintaining surgical skills for military general surgery: the potential role for multivisceral organ retrieval in military general surgery training and practice.

The closure of the Medical Treatment facility in Camp BASTION and the return to contingency operations presents a new challenge in training and maintaining the skills of military surgeons. Multivisceral organ retrieval presents a unique opportunity to practice some of the more unusual techniques required in military surgery in the National Health Service. This article details the experience that organ retrieval offers and matches this to the needs of military surgeons. National Organ Retrieval Service teams need skilled surgeons, and a mutually beneficial partnership is in prospect.

Feasibility RCT of definitive chemoradiotherapy or chemotherapy and surgery for oesophageal squamous cell cancer.

BACKGROUND: The optimal treatment for localised oesophageal squamous cell carcinoma (SCC) is uncertain. We assessed the feasibility of an RCT comparing neoadjuvant treatment and surgery with definitive chemoradiotherapy. METHODS: A feasibility RCT in three centres examined incident patients and reasons for ineligibility using multi-disciplinary team meeting records. Eligible patients were offered participation in the RCT with integrated qualitative research involving audio-recorded recruitment appointments and interviews with patients to inform recruitment training for staff. RESULTS: Of 375 patients with oesophageal SCC, 42 (11.2%) were eligible. Reasons for eligibility varied between centres, with significantly differing proportions of patients excluded because of total tumour length (P=0.002). Analyses of audio-recordings and patient interviews showed that recruiters had challenges articulating the trial design in simple terms, balancing treatment arms and explaining the need for randomisation. Before analyses of the qualitative data and recruiter training no patients were randomised. Following training in one centre 5 of 16 eligible patients were randomised. CONCLUSIONS: An RCT of surgical vs non-surgical treatment for SCC of the oesophagus is not feasible in the UK alone because of the low number of incident eligible patients. A trial comparing diverse treatment approaches may be possible with investment to support the recruitment process.

Assessment and comparison of recovery after open and minimally invasive esophagectomy for cancer: an exploratory study in two centers.

BACKGROUND: Minimally invasive esophagectomy (MIE) may lead to early restoration of health-related quality of life, but few prospective comparative studies have been performed. This exploratory study compared recovery between totally minimally invasive esophagectomy (MIE), laparoscopically assisted esophagectomy (LAE) and open surgery (OE). METHODS: A prospective study in 2 specialist centers recruited consecutive patients undergoing OE, LAE, or MIE for high-grade dysplasia or cancer. Patients completed validated questionnaires, the Multi-Dimensional Fatigue Inventory (MFI-20), modified Katz Scale, and modified Lawton and Brody Scale (assessing activities of daily living) before and 6 weeks and 3 and 6 months after surgery. RESULTS: A total of 97 patients (26 women; median age 64 years) were scheduled for surgery that was abandoned in 11 due to occult low-volume metastatic disease. In the remaining 86 (OE = 19, LAE = 31, and MIE = 36), there were 4 in-hospital deaths (4 %), and 54 postoperative complications (OE = 12, LAE = 19, and MIE = 23). Overall questionnaire compliance was high (77 %) and baseline scores similar in all groups, although clinical differences between groups were observed with earlier tumors and more squamous cell cancers selected for MIE. Following surgery fatigue levels increased dramatically and activity levels reduced in all groups. These gradually recovered to baseline following MIE and LAE within 6 months, but the ability to perform activities of daily living and most parameters of fatigue had not returned to baseline levels in the OE group. CONCLUSIONS: This exploratory prospective nonrandomized study of recovery after different types of surgery for esophageal cancer showed possible small benefits to MIE. A much larger study is needed to confirm these findings.

The management of acute appendicitis.

Appendicitis is the most common general surgical condition and peaks in incidence at the age of those serving in the military. Diagnosis can be extremely difficult with very vague signs and symptoms. This review aims to highlight management considerations that should be taken into account when faced with appendicitis in a military setting, including in the pre-hospital and pre-shore environment. Current controversies surrounding appendicitis management, and the effect these might have on the management of the military patient, are debated.

Difficult decisions in the surgical care of military casualties with major torso trauma.

Testing and difficult decision-making is a sine qua non of surgical practice on military operations. Better pre-hospital care protocols, reduced evacuation timelines and increased scrutiny of outcome have rightfully emphasised the requirement of surgeons to "get it right, first time and every time" when treating patients. This article addresses five contentious areas concerning severe torso trauma, with relevant literature summarised by a subject matter expert, in order to produce practical guidance that will assist the newly deployed surgeon in delivering optimal clinical outcomes.

Elevated body mass disrupts the barrier to gastroesophageal reflux; discussion 1018-9.

HYPOTHESIS: Obesity impairs the antireflux function of a structurally intact barrier. DESIGN: Retrospective analysis of body mass index in patients with normal esophageal manometric findings but with symptomatic and objectively confirmed gastroesophageal reflux. SETTING: Specialist esophageal center. PATIENTS: Patients symptomatic and diagnostic for gastroesophageal reflux, referred between October 1, 1998, and June 30, 2000. Exclusion criteria were a defective barrier, motility disorders, or previous surgery. MAIN OUTCOME MEASURES: Reflux was defined and quantified using the DeMeester score, and body mass index was calculated. RESULTS: There was a strong correlation between body mass index and severity of gastroesophageal reflux. Patients who were overweight had significantly higher distal esophageal acid exposure. No significant difference in manometric findings was demonstrated between patients with normal weight and those who were overweight. CONCLUSION: The barrier to gastroesophageal reflux is rendered insufficient in patients who are overweight.

The crura and crura-sphincter pressure dynamics in patients with isolated upright and isolated supine reflux.

The reason why patients with isolated supine reflux do not reflux in the upright position and patients with isolated upright reflux do not reflux in the supine position is unknown. Our objective was to determine the characteristics of the crura, lower esophageal sphincter, crura-sphincter dynamics, and esophageal body on manometry, endoscopy, and X-ray in patients with isolated upright and isolated supine reflux. Eighty consecutive patients with isolated upright reflux were compared with 82 consecutive patients with isolated supine reflux. Manometrically there was no difference in lower esophageal sphincter characteristics and esophageal contractions between the two groups. The prevalence of a hiatal hernia on manometry was similar between upright and supine refluxers (88% vs 88%). Upright refluxers had shorter hiatal hernias [median (interquartile range) 1.1 (0.65-1.8) vs 1.2 (1-2.3), P < 0.046)]. The median crural pressure, crura-sphincter pressure gradient, and crura-sphincter pressure ratio in upright refluxers was 14.96 (9.5-21.27), 3.28 (1.7-12.2), and 1.33 (0.87-2.8) mm Hg, respectively. These values were significantly higher (P < 0.001) in supine refluxers at 21.43 (16.6-29.9), 10.66 (4.3-19.7), and 2.1 (1.3-4.2) mm Hg, respectively. We conclude that the significantly higher crural pressure in patients with supine reflux acts as a mechanical ring and as a physiologic protector against the unfolding of the sphincter in the postprandial and upright periods. Higher crura-sphincter pressure gradient and larger-size hiatal hernias in patients with supine reflux results in pressurization of the hernia sac and subsequent reflux when these patients are in a supine position.

Aorto-conduit fistula developing four years after esophagectomy.

A 71 year old lady was treated for a squamous cell carcinoma of the oesophagus with neo-adjuvant chemotherapy followed by a two phase Ivor-Lewis oesophagectomy with two field lymphadenectomy. She presented four years later with life threatening bleeding from a fistula between the thoracic aorta and the gastric conduit, which was treated successfully with a thoracic aortic stent.

Adenotonsillectomy in children: a comparison of morphine and fentanyl for peri-operative analgesia.

This study compared the effectiveness and side-effects of intra-operative fentanyl with fentanyl and morphine for elective adenotonsillectomy in a double-blind study, in 60 children randomly allocated to receive either intravenous fentanyl 1 microg x kg(-1) intra-operatively or intramuscular morphine 100 microg x kg(-1) at induction. All children received a standard anaesthetic induction with intravenous fentanyl 1 microg x kg(-1) and propofol 4-5 mg x kg(-1) and maintenance with oxygen, nitrous oxide and isoflurane. Pain scores, emetic episodes and supplemental morphine requirements were recorded for 24 h postoperatively. The overall incidence of postoperative vomiting was high in both groups: 70% in the fentanyl group and 78% in the morphine group. The incidence of postoperative vomiting was lower in the fentanyl group (p < 0.03) in the first 4 h, but similar by 24 h. Children who received morphine at any time in the first 24 h had more median (range) episodes of vomiting [2 (0-7)] than children receiving fentanyl only [l (0-3); p < 0.03]. Administration of rescue anti-emetics, pain scores in recovery and pain scores over the next 24 h were similar between the two groups.
