Audit of preoperative localisation of tumor with tattoo for patients undergoing laparoscopic colorectal surgery.

BACKGROUND: Preoperative localisation of tumour is an essential requirement in laparoscopic colorectal surgery. Since the introduction of laparoscopic colorectal resections in NGH in February 2010, the difficulties of tumour localisation at the time of surgery without tattoo have been highlighted. Furthermore, endoscopic documentation of site of tattoo with respect to the tumour can be inconsistent and at times misleading or difficult to interpret. Tattooing guidelines should be simple to follow and consistent for all lesions irrespective of the location of the tumour. The recommendations were to place at least three spots of tattoo one mucosal fold distal to the lesion and clearly document site of tattoo with respect to tumour in the endoscopy report. METHOD: We identified 100 patients undergoing elective laparoscopic colorectal cancer resections over a two-year period. Data were collected regarding presence of tattoo preoperatively as documented in the colonoscopy report and subsequently the visibility of the tattoo at time of laparoscopy and its accuracy in relation to the tumour. Abdominoperineal resections and emergency colorectal operations were excluded. RESULTS: Only 59% of the patients had a visible and accurate tattoo. In 17% of the patients, the tattoo was not visible at all, although it was documented in the endoscopy report that it had been administered. In 4% of patients, it was visible but inaccurately placed. In 20% of the patients, there were no tattoos at all, necessitating on table endoscopy and intraoperative specimen analysis to confirm that the tumour/lesion was within the resection specimen. DISCUSSION: Preoperative tumour localisation is extremely important to correctly identify the site of tumour or lesion at laparoscopy. A standardised departmental protocol should be implemented by all endoscopists to place three spots of tattoo one mucosal fold distal to any significant lesions found. Failure to tattoo lesions/cancers preoperatively can lead to intraoperative delays and potential harm to patients from on-table endoscopy.

Is estimated intra-operative blood loss a reliable predictor of surgical outcomes in laparoscopic colorectal cancer surgery?

BACKGROUND: Studies have shown that laparoscopic surgery for colorectal cancer is often associated with significantly reduced intra-operative blood loss compared to the corresponding open procedures. Increased intra-operative blood loss can be associated with increased risk of post-operative morbidity and mortality. We sought to determine whether estimated intra-operative blood loss was a reliable predictor of post-operative surgical outcomes. METHOD: Prospective data were collected for patients undergoing elective laparoscopic colorectal cancer resections from July 2011 to November 2013. Weighing swabs and measuring blood volume in suction devices calculated the estimated intra-operative blood loss. The operative outcome data including post-operative 30 day morbidity and mortality, length of hospital stay, re-admission and re-operation within 30 days were collected. The operative blood loss was grouped into Group 1 (less than 50 ml, Group 2 (50-150 ml) and Group 3 (over 150 ml). Patients who underwent open operations and laparoscopic conversions were excluded. RESULTS: The median age, length of hospital stay, male to female ratio and body mass index were similar in the three groups. There was no 30-day mortality in any of the groups. The number of re-admissions within 30 days was similar in all groups. The re-operation rates within 30 days were higher in Groups 2 and 3 at 11% and 8.6%, respectively. The post-operative complications were 12.5%, 16.7%, and 26% in groups 1, 2 and 3, respectively. There were no anastomotic leaks requiring re-operation noted in Group 3. DISCUSSION: This study has shown that intra-operative blood loss was not associated with increased median length of stay nor did it increase the 30 day re-admission rate. However, increased intra-operative blood loss was associated with increased incidence of post-operative morbidity and risk of reoperation within 30 days.

Laparoscopic colorectal surgery: Is it beneficial in the over 80s?

INTRODUCTION: Advanced age is often associated with higher incidence of co-morbidities, advanced cancer and post-operative complications. The aim of this study was to compare the differences in pre-operative, co-morbidities, cancer stage and surgical outcome measures between patients over the age of 80 and those below 80 undergoing elective laparoscopic colorectal resection. METHOD: Data were analysed from a prospectively maintained database between February 2011 and June 2012 and patients were subdivided into two groups (over 80 and under 80). All patients underwent laparoscopic colorectal surgery. Their length of stay, high dependency unit/intensive therapy unit stay, American Society of Anaesthesiologists grade, co-morbidities, conversion rates, Dukes' stage and post-operative complication rates were compared. RESULTS: Of the 67 patients in the study, 57 were <80 at the time of surgery. Their American Society of Anaesthesiologists grade prior to surgery, as expected, was better than that of the >80 group, with 23% having an American Society of Anaesthesiologists grade of 3 compared to 60% in the >80%. The prognosis of the patients in the two groups based on Dukes' stage was similar, with 63% of the <80 s having a good prognosis, compared to 80% in the >80 s. (Good prognosis = Dukes' A or B). The conversion rates were similar (26% of the <80 s compared to 20% of the > 80 s) Post-operative length of stay was also similar in both groups (<80 s vs. >80 s: median 5 vs. 5; p = 0.33). Post-operative complication rates were similar (17% of the <80 s vs. 20% of the >80 s). CONCLUSION: The short-term outcomes following laparoscopic colorectal surgery in the elderly are similar to that of younger patients. Laparoscopic surgery should therefore be offered to all patients irrespective of age.

Glue granuloma following laparoscopic hernia repair.

Minimal inflammation of tissues can occur following skin closure with a foreign material. This foreign body reaction can lead to granuloma formation. We report the case of a middle-aged man who, having undergone laparoscopic surgery and had the port site wounds closed with skin glue, was detected to have a non-healing wound. A crystal mass protruding from the incision site was confirmed histologically as a chronic granulomatous reaction to skin glue. A foreign body granulomatous reaction to skin glue has not been described in the literature.

Conservative treatment of splenic infarction and intestinal obstruction caused by a wandering spleen.

The underdevelopment or absence of the splenic suspensary ligaments can lead to an uncommon condition termed the wandering spleen. It is usually asymptomatic but can present with an acute abdomen when associated with torsion. Most authors advocate surgical treatment. Herein, we report a case of torsion with infarction of the spleen and intestinal obstruction in a 36-year-old female patient which was successfully managed conservatively.

Patient education videos for elective colorectal surgery: results of a randomized controlled trial.

AIM: Recent advances in surgery have focused on peri-operative care and interventions to improve outcome following surgery. Psychological preparation has a positive impact on recovery and incorporates a range of strategies with dissemination of information as one of the key elements. Information can be given verbally, through printed information or through use of a video. Traditionally, reliance has been on the use of written material as an adjunct to patient education in clinic. The current study is a randomized trial on the use of video education in patients undergoing elective colorectal resection within an enhanced recovery programme. METHOD: Sixty-five eligible patients undergoing elective colorectal surgery were identified and 61 were randomized between August 2010 and August 2011 to either video and information leaflets or information leaflets alone. A fast track protocol was established for all the patients. Clinicians in charge of postoperative recovery were blinded. Standard discharge criteria were employed for all patients. RESULTS: Of 61 patients randomized, one dropped out and outcomes on 60 were analysed. There was no difference in baseline characteristics between the groups (age, P = 0.964; body mass index, P = 0.829). Twenty-eight (91%) patients in the video group had left sided resections while two (6%) had right sided resections. Nineteen (66%) in the non-video group had left sided resections while nine (31%) had right sided resections. One (3%) patient in the non-video group and one (3%) in the video group had a total colectomy. Fourteen (45%) patients in the video group and 12 (41%) in the non-video group had surgery completed laparoscopically. There was no difference in the primary (median hospital stay 5 vs 5 days; P = 0.239) or the secondary outcome measures (pain score on movement, P = 0.338; pain score at rest, P = 0.989; nausea score, P = 0.74; epidural use, P = 0.984; paracetamol use, P = 0.44; voltarol use, P = 0.506) between the groups. CONCLUSION: Use of video education in the psychological preparation of patients undergoing elective colorectal surgery does not improve short-term outcomes.

Closure of loop ileostomies: is early discharge safe and achievable?

A prospective audit of the complications associated with reversal of a loop ileostomy was carried out between March 2000 and March 2005. The complication rate, length of inpatient hospitalisation and re-admission rate were assessed in 100 patients, in a single clinical practice. The median (interquartile range) length of time between the primary procedure and closure was 133 days (120-270) days. Median length of inpatient stay was two days (one - three) days. The overall complication rate was 18%. One patient had a post-operative leak leading to local abscess formation. This was drained surgically after initial failure with radiological drainage. A second patient had a late leak, three weeks after closure, leading to fistula formation. This patient required surgical resection of the anastomosis after failure of conservative management. Twelve patients were re-admitted with small bowel obstruction (12%), of whom 11 were managed conservatively, while one underwent further surgery. There was one post- operative death as a result of acute cardiac failure secondary to undiagnosed hypertensive cardiomyopathy. Thus early discharge following closure of a loop ileostomy, can be achieved with an acceptably low serious complication rate.

Para-spinal abscess following gallstones spillage during laparoscopic cholecystectomy: an unusual presentation.

Gallbladder perforation with subsequent gallstone spillage can occur with higher frequency in laparoscopic cholecystectomy than in traditional open approach. Gallstone abscess formation from stone spillage post-cholecystectomy is extremely rare. We present a case of para-spinal abscess formation 5 years after spilled gallstones following laparoscopic cholecystectomy.

Hernias are the most common cause of strangulation in patients presenting with small bowel obstruction.

BACKGROUND: Small bowel obstruction (SBO) is a leading cause of admission to surgical emergency units. Strangulation is associated with a 10-fold increase in mortality. The aim of the present study was to identify the most frequent causes of strangulation in patients presenting with small bowel obstruction. METHODS: A prospective study was conducted of all patients presenting with SBO in one teaching hospital between 2003 and 2004. RESULTS: One hundred and sixty-one patients with symptoms and signs of small bowel obstruction were admitted. Eighty-three were confirmed with contrast studies. The male:female ratio was 1:1.6. The aetiology of obstruction was adhesions in 97 patients (60.2%), hernia in 29 (18%), malignancy in 17 (10.6%) and miscellaneous causes in 18 (11.2%). Operative procedures were performed on 74 patients (46%), 31 of them (42%) with adhesions, 25 (34%) with hernias and 18 (24%) due to other causes. Strangulated bowel occurred in 15 patients (9.3%); 12 had hernias whilst three had adhesions (P < 0.0001). Of the strangulated hernias, ten were femoral, one was inguinal and one was paraumbilical. There were seven deaths; three occurred in patients declared unfit for surgery, while four occurred post-operatively - two had strangulated bowel, the other two had advanced cancer. CONCLUSION: Whilst adhesions are the most common cause of small bowel obstruction, hernias remain the most frequent cause of strangulation in patients presenting with this condition.

Do creatine kinase (CK) levels influence the diagnosis or outcome in patients with compartment syndrome?

We report a retrospective study in patients with compartment syndrome with the aim to analyse: 1) whether the level of rise in CK levels is a useful marker to the presence of compartment syndrome and; 2) whether an early fasciotomy assists in lowering of the elevated CK levels. The results of our study suggest that although raised CK levels are not diagnostic, they are a useful adjunct in making a diagnosis, and hence CK estimation should be done in all patients with suspected compartment syndrome. Moreover, an early fasciotomy (< 12 hours) has a statistically significant influence in lowering elevated CK levels, confirming the view that the earlier the decompression, the lesser the muscle damage.

Inflammatory pseudotumour of the caecum: a case report.

Inflammatory pseudotumors of the caecum are uncommon. They pose problems with diagnosis. We report on a 35 year old female who presented with clinical signs of acute appendicitis. Intra-operatively, a caecal tumour was found with normal appendix and multiple enlarged mesenteric lymph nodes. A right hemicolectomy was performed. Histopathology findings revealed an inflammatory mass with abundant fibroblast proliferation with associated collagen formation, infiltrating bowel wall and pericaecal adipose tissue. She recovered well and was discharged home 5 days post-operatively. At present, she is free of symptoms.

Jejunal diverticulitis in a child.

Jejunal diverticular disease is rare and few cases have been documented in the literature. Here we report the first case of a child presenting with a perforated congenital jejunal diverticulum.

An unusual presentation of Meckel's diverticulum.

Meckel's diverticulum can present with unusual symptoms and signs and therefore delay diagnosis. We present the case of a 63 year old lady who presented to the gynaecologists with a huge right sided ovarian cyst. She had required 13 units blood transfusion previously (5 years ago) for massive gastrointestinal bleed with no cause found despite extensive investigations. At operation she was found to have a Meckel's diverticulum in the left lumbar region containing a large calculus. She had an unremarkable post-operative course.

Preparation for elective colorectal surgery using a video: a questionnaire-based observational study.

OBJECTIVE: Every patient has a perception about surgery and psychological preparation of the patient has an important impact on their postoperative recovery and outcome. In this study we looked at impact of a visual educational aid, in the form of a patient DVD on outcome following colorectal surgery within an enhanced recovery programme (ERP). DESIGN: We carried out a prospective analysis of a consecutive series of patients undergoing elective colorectal resection. All patients were given information about their operation in a clinic setting. Our intervention included a 15 minute patient educational video describing the preoperative assessment, post-operative recovery and advice on discharge. A questionnaire on patients' views of ERP and video education was given on discharge. SETTING: University teaching hospital PARTICIPANTS: Patients undergoing elective colorectal resection MAIN OUTCOME MEASURES: Outcomes studied included length of hospital stay, patient perception of ERP, postoperative complications and readmissions: RESULTS: Thirty-two patients underwent elective colorectal surgery over a 3 month period. Median length of stay in hospital was 5 days. The questionnaire response rate was 100%. All patients thought they were well informed of the enhanced recovery programme. Eighty-eight percent responded that the video information provided about their operation was adequate, with 28% finding the video very helpful and more useful than other forms of patient information. There were no major postoperative complications and no readmissions. CONCLUSION: Audiovisual presentation in the form of a patient video is a useful tool in the psychological preparation of patients undergoing colorectal surgery.

An unusual extraction; retrieval of a swallowed crown by appendicectomy.

We report the case of a patient who swallowed a crown and three weeks later presented with abdominal pain and fever. At operation his crown was found to be causing appendicitis. Foreign bodies have previously been reported as causing appendicitis but never a crown. We discuss the appropriateness of abdominal radiology in the management of such foreign bodies.

Laparoscopic colonic resection in fast-track patients does not enhance short-term recovery after elective surgery.

BACKGROUND: Laparoscopic colorectal surgery has been claimed to enhance recovery when compared with open surgery. The aim of our study was to investigate whether laparoscopic colorectal resection improved recovery with the use of a multimodal rehabilitation programme. METHOD: We carried out a prospective audit of 80 patients undergoing elective colorectal resection between November 2003 and March 2005. All patients underwent a fast-track protocol with early feeding, mobilization and a fluid and sodium restriction regime. Recovery was measured in terms of return of gastrointestinal function, hospital stay, complications and quality of life measures. RESULTS: Of the 80 patients in the study 22 underwent laparoscopic resection and 58 had open surgery. Patients were well matched for all baseline characteristics. The groups were not significantly different in terms of opioid or antiemetic use. They were also similar in median time to first flatus (69 h vs 69 h, P = 0.36) and median time to first bowel motion (127 h vs 101 h, P = 0.07). There was no difference in median hospital stay (5.8 days vs 5.9 days, P = 0.87) or complications (P = 0.46) between the laparoscopic and open group. There were no significant differences in Short Form 36 scores between the two groups for any of the components measured. CONCLUSION: Laparoscopic colorectal resection does not appear to reduce the duration of ileus or hospital stay with the use of a multimodal rehabilitation regime. Further large randomized trials are required to confirm these findings.
