Quality of life amongst patients with diverting umbilical stomas in rectal surgery: a single centre prospective randomized controlled pilot study.

BACKGROUND: The umbilical stoma (umbistoma) has been proposed as a viable alternative site for a temporary defunctioning stoma. Suggested advantages of the umbistoma include decreased number of surgical incisions required, improved cosmesis and ease of reversal surgery. This study aimed to assess the patient experience of umbilical loop ileostomies in rectal surgery, with the primary outcome being patient reported quality of life (QoL). METHODS: A total of 20 patients undergoing laparoscopic rectal cancer surgery were randomly allocated to have a defunctioning ileostomy at a conventional site (right iliac fossa) or at the umbilicus. Patient-reported QoL was assessed at 6 weeks using the Stoma-QoL questionnaire. Secondary outcomes were number of stomas reversed, length of time awaiting stoma reversal surgery, duration of operative time for stoma reversal, length of hospital stay following stoma reversal and rate of parastomal or post reversal incisional hernias. RESULTS: Patients who had an umbilical stoma scored significantly lower on the Stoma-QoL questionnaire compared to the conventional group, particularly on questions regarding feelings of tiredness, body insecurity and anxiety. No significant differences were observed between the two groups in relation to secondary outcomes. CONCLUSION: There may be potential disadvantages to the umbilical stoma with negative impacts on body image and subsequent increased social anxiety. Patient selection and adequate counselling will be important when considering an umbilical stoma. Further larger scale prospective studies are required to further validate the feasibility and longer-term safety of umbilical stomas in both clinical outcomes as well as patient QoL.

An unwelcome guest: two cases of colonic metastatic lobular breast cancer.

Metastatic spread of invasive lobular breast cancer is rare. It can have a delayed and varied presentation that can mimic other bowel pathologies, such as colorectal cancer and inflammatory bowel disease, making its diagnosis difficult. In this study, we present two patients who required colonic resection due to malignant obstruction caused by metastatic invasive lobular carcinoma of the breast.

Elective Laparoscopic Cholecystectomy as an Entrustable Professional Activity (EPA) for General Surgical Trainees in Australia.

INTRODUCTION: To evaluate the operation time and surgical outcomes of elective laparoscopic cholecystectomy performed by surgical trainees at different levels of training at Eastern health and hence, to establish the efficacy and safety of elective laparoscopic cholecystectomy as an Entrustable Professional Activity for surgical trainees in general surgery. OBJECTIVE: Elective laparoscopic cholecystectomies performed at our institution between January 2018 and January 2019 were included. Analyses were divided among three groups - consultants (C), fellows (F) and registrars (R). Standard technique with critical view of safety was used. RESULTS: A total of 592 patients was included, with a mean age of 54 ± 63 years old. The average operation time was 84 ± 51 minutes. Surgical education and training (SET) 2 trainees took significantly longer when compared to their SET3 and above counterparts as a primary operator (SET2: 131 ± 32 min, Reference; SET3: 78 ± 21 min, p = 0.003; SET4: 80 ± 33 min, p = 0.004; SET5: 77 ± 28 min, p = 0.003; F: 93 ± 77 min, p = 0.036; C: 85 ± 59 min; p = 0.007). Consultant primary operators took an average of 15 minutes longer to complete the operation when assisted by a SET trainee compared to the non-SET registrars (p = 0.03). The overall complication rate was 3.2% and was not significantly different among all three groups (p = 0.17). No death was recorded during the study period. The readmission and return to theatre rates were 7.8% and 0.8% respectively and were not significantly different among the groups (p-values = 0.61 and 0.69). All conversion to open were performed by the consultant primary operator. CONCLUSIONS: Elective laparoscopic cholecystectomy can be safely performed by surgical trainees at all SET levels when under appropriate supervision, although junior surgical trainees that is SET 2 took longer to complete the procedure. This operation seems to have a steep, but relatively short, learning curve and it may be broken down into various components. These components, with the addition of time, may be suitable as an Entrustable Professional Activity tool for assessing the competency of early SET trainees.

Sensitivity of pre-operative imaging and radiologist inter-rater reliability in detecting lesions in Crohn's disease.

BACKGROUND: Computed tomography (CT), computed tomography enterography (CTE) and magnetic resonance enterography (MRE) are commonly used pre-operatively in surgical planning in Crohn's Disease (CD). The findings on CT, CTE and MRE may not, however, correlate with operative findings. This study aims to establish the sensitivity of these imaging modalities and analyse radiologist inter-rater reliability by comparing imaging findings of strictures, fistulas and abscesses with intra-operative findings. METHODS: A retrospective review of CD patients who had either CT, CTE and/or MRE imaging and CD related surgical intervention at a public health service from 2010 to 2019 inclusive. The number and locations of strictures, fistulas and abscesses on pre-operative original radiology reports (OR) were recorded. Subsequently, all scans were re-read by two specialist abdominal radiologists and consensus recorded (SR). Lesions recorded from both OR and SR were compared to those found intra-operatively. RESULTS: Eighty-three patients were included. For strictures, sensitivity was 67%, 74% and 79% for OR and 88%, 71% and 87% for SR for CT, CTE and MRE respectively. The frequency of fistulas and abscesses were small hence a conclusion could not be drawn. The level of agreement between radiologists ranged from 44% to 82% for strictures and 64 to 100% for fistulas and abscesses across all three imaging modalities. CONCLUSIONS: CT and MRE have similarly high sensitivities for the identification of strictures pre-operatively when read by specialist radiologists. Inter-rater reliability calculations found similar agreement levels between specialist radiologists and between OR and SR for strictures, fistulas and abscesses across CT, CTE and MRE.

Pudendal Nerve Block for Posthemorrhoidectomy Pain: A Prospective, Single-Blinded Randomized Control Trial.

BACKGROUND: Postoperative pain is common in hemorrhoidectomy patients. Local anesthetic given either as an intraoperative pudendal nerve block or as a local wound infiltration may help alleviate postoperative pain. OBJECTIVES: This study sought to determine whether the addition of an intraoperative pudendal nerve block to a perianal local wound infiltration and standardized analgesia regimen was superior to a perianal local wound infiltration and standardized analgesia regimen alone in reducing early postoperative pain following hemorrhoidectomy. The secondary objective was to measure differences between treatment groups in perceived perianal numbness, oral opioid requirements, and adverse events. DESIGN: This study was a prospective, single-blinded randomized controlled trial approved by the Eastern Health Human Research and Ethics Committee in Melbourne, Australia (registration number: E09/2014). SETTINGS: Patients were recruited across 3 Australian hospitals. PATIENTS: Eighty patients with symptomatic hemorrhoids requiring hemorrhoidectomy in colorectal surgical outpatient clinics were successfully recruited and enrolled in the study, with 1 patient later dropping out. INTERVENTION: Patients were randomly assigned to either the pudendal nerve block group or a control group. The pudendal nerve block group received 5 mL bupivacaine 0.5% with adrenaline 1:200,000 to both pudendal nerve trunks bilaterally. Both groups received 10 mL of the same local anesthetic injected into the post-hemorrhoidectomy wound bed. MAIN OUTCOME MEASURES: Visual analogue scales were used to record patient pain scores. Dichotomous (yes/no) answers were recorded for secondary objectives. RESULTS: There were no significant differences in postoperative pain between groups at 4 hours, 8 hours, 12 hours, or 24 hours. Additionally, there were no significant differences between groups with respect to perceived perianal numbness, oral opioid usage or adverse events. LIMITATIONS: The authors recognize that without a nerve stimulator, an argument can be made that the pudendal nerve block was not actually achieved. CONCLUSION: Pudendal nerve block does not appear to demonstrate additional benefit in post-hemorrhoidectomy pain reduction beyond local anesthetic to the wound.

BLOQUEO DEL NERVIO PUDENDO PARA EL DOLOR POSHEMORROIDECTOMA ESTUDIO PROSPECTIVO, ALEATORIO, CONTROLADO, CIEGO: ANTECEDENTES:El dolor posoperatorio es común en pacientes luego de una hemorroidectomía. La administración de anestésico local como bloqueo del nervio pudendo intraoperatorio o infiltración local de la herida puede ayudar a aliviar el dolor posoperatorio.OBJETIVOS:Determinar si agregar un bloqueo intraoperatorio del nervio pudendo a una infiltración local perianal de la herida y un régimen de analgesia estandarizado fue superior a una infiltración local perianal de la herida más un régimen de analgesia estandarizado para reducir el dolor posoperatorio precoz después de una hemorroidectomía. Los objetivos secundarios incluyeron sensación de adormecimiento perianal, requerimientos de opioides orales y eventos adversos informados.DISEÑO:Este estudio fue un ensayo controlado aleatorio, prospectivo, ciego, aprobado por el Comité de Ética e Investigación en Humanos de Eastern Health en Melbourne, Australia (número de registro: E09 / 2014).ESCENARIO:Los pacientes fueron reclutados en tres hospitales australianos.PACIENTES:Ochenta pacientes se inscribieron con éxito en el estudio, y más tarde un paciente abandonó.INTERVENCIÓN:Los pacientes fueron asignados al azar al grupo de bloqueo del nervio pudendo o al grupo control. El grupo de bloqueo del nervio pudendo recibió 5 ml de bupivacaína al 0,5% con adrenalina 1: 200.000 en ambos troncos del nervio pudendo bilateralmente. Ambos grupos recibieron 10 ml del mismo anestésico local inyectado en el lecho de la herida posterior a la hemorroidectomía.PRINCIPALES VARIABLES ANALIZADAS:Se utilizaron escalas analógicas visuales para registrar las puntuaciones de dolor del paciente. Se registraron respuestas dicotómicas (sí / no) para los objetivos secundarios.RESULTADOS:No hubo diferencias significativas en el dolor posoperatorio entre los grupos a las 4, 8, 12 o 24 horas. Además, no hubo diferencias significativas entre los grupos con respecto al adromecimiento perianal percibido, el uso de opioides orales o los eventos adversos.LIMITACIONES:Sin el uso de un estimulador nervioso, se puede argumentar que el bloqueo del nervio pudendo no se logró realmente.CONCLUSIÓNES:El bloqueo del nervio pudendo no parece demostrar un beneficio adicional en la reducción del dolor posterior a la hemorroidectomía más allá del anestésico local en la herida.

An unusual case of caecal perforation following ileostomy reversal.

A 63-year-old man with a history of gastro-oesophageal reflux disease underwent defunctioning loop ileostomy for obstructing metastatic rectal cancer prior to receiving long-course neoadjuvant chemoradiotherapy. Four months post completion of neoadjuvant therapy, he underwent an uncomplicated elective ultra-low anterior resection with formation of colonic J pouch and first stage liver metastasectomy for bilobar liver disease. At 1 year, he proceeded to an elective closure of loop ileostomy. Unfortunately, his postoperative course was complicated by profuse diarrhoea with subsequent colonic perforation, necessitating an emergency laparotomy and ileocolic resection with end ileostomy formation. Histopathology and stool studies were consistent with Salmonella Typhi infection. At the present time, Salmonella Typhi causing toxic megacolon and subsequent colonic perforation is an uncommon phenomenon in Australia. Here, we present an unusual case and explain why bowel perforation in this instance likely had a multifactorial aetiology.

Anastomotic Failure in Colorectal Surgery: Where Are We at?

Anastomotic leak (AL) can be a devastating complication in colorectal surgery. While it is less frequent in the modern era, it still results in significant morbidity and mortality, prolonged hospital stays and increases the costs and demands on health services. There is inevitable interplay between patient physiology and technical factors that predispose a patient to AL. Obesity, preoperative total proteins, male gender, ongoing anticoagulant treatment, intraoperative complication and number of hospital beds have been identified as independent risk factors. This has led to an online risk calculator for AL. Non-steroidal anti-inflammatory drugs and neoadjuvant chemoradiotherapy have also been implicated, but no significant evidence has yet been found to support causation. In addition, technical factors such as type of anastomosis, mechanical bowel preparation, drains, omentoplasty and faecal diversion have failed to show significant differences in AL rates. Early diagnosis and intervention in AL is essential in reducing the rates of morbidity and mortality. Clinical assessment has high sensitivity but low specificity and should be used in combination with imaging techniques to get a diagnosis. C-reactive protein is also a useful marker. The management will depend on the grade of AL and the clinical state of the patient. Management options include conservative measures such as antibiotics and/or percutaneous drainage to more invasion procedures such as open drainage and/or Hartmann's procedure. In conclusion, ALs will forever pose challenges to the surgeon in diagnosis and management. It is often the yardstick by which each surgeon is measured and is the source of significant morbidity to patients and health care services worldwide. As a result, a low threshold for investigation and intervention is mandatory to ensure better outcomes and lower overall mortality and morbidity.

Patients' perspective on bowel resection for inflammatory bowel disease.

PURPOSE: The study aimed to determine whether patients are receiving adequate counselling about elective bowel resection and timely surgery for inflammatory bowel disease (IBD). METHODS: Patients with IBD who underwent an elective bowel resection in a tertiary referral centre between April 2012 and Dec 2014 were identified from a prospective database. Patients under the age of 16 years were excluded from the study. Patients were contacted over the phone to complete a questionnaire regarding their perspective on their surgery, including the consultations that took place, preparedness and timing of surgery, as well as patient attitude towards bowel resection and satisfaction with post-operative outcomes. Demographic details were recorded. RESULTS: Thirty-one patients participated in the study. Twenty-one (68%) patients were diagnosed with Crohn's disease, nine (29%) were diagnosed with ulcerative colitis, and one (3%) had indeterminate colitis. Twenty-seven (87%) patients reported that the timing of the initial consultation regarding the option of bowel resection was appropriate. Twenty-five (81%) patients felt prepared after a consultation with the surgical team with regard to perioperative issues and potential complications. Fourteen (45%) patients reported that the timing of bowel resection was appropriate, while 15 (48%) reported that it should have been earlier. A significant improvement in patient's pre- and post-operative attitudes towards bowel resection was demonstrated (p = 0.004). Thirty (97%) patients were either happy or very happy with their results and symptom improvement post-bowel resection. CONCLUSION: Most patients are receiving adequate counselling about elective bowel resection for IBD, although there is room for improvement for preoperative education and optimising timing of surgery.

Endoscopic balloon dilatation of Crohn's strictures: a safe method to defer surgery in selective cases.

BACKGROUND: Endoscopic balloon dilatation (EBD) provides a valuable alternative to surgery for strictures in Crohn's disease (CD). Data are lacking regarding the factors that improve the safety and effectiveness of EBD in CD. The aim of this study is to determine the safety and efficacy of EBD and the clinical variables, which are predictive of successful treatment of CD strictures with EBD. METHODS: The records of all patients with CD in whom EBD was attempted between 2008 and 2013 were reviewed. Procedures were conducted at a single tertiary referral centre using a Boston Scientific CRE® TTS balloon. Technical success was defined as the ability to traverse the stricture with the endoscope and clinical success as the resolution of obstructive symptoms at review. RESULTS: Forty-seven patients with a total of 58 strictures (19 primary and 39 anastomotic strictures) were treated with EBD with median follow-up of 37 months. A total of 161 dilatation procedures were performed, with technical success reported in 139/158 (88%) cases and clinical success reported in 105/137 (76.7%) cases with complete data. Complications occurred in 7/161 dilatations (4.3% dilatations, 15% patients), three patients with perforation, one with acute bleeding and three admitted with abdominal pain. Eighteen of the 47 patients required surgery (38%). Strictures of <50 mm (P = 0.04) and those dilated to a diameter of ≥15 mm (P = 0.031) were less likely to require surgical resection. CONCLUSIONS: EBD is safe for both primary and post-surgical strictures. Stricture length and diameter of dilatation are predictive of success. In selected patients, treatment with EBD may reduce or delay the need for surgery.

Early surgery in Crohn's disease a benefit in selected cases.

AIM: To compare the outcomes of a cohort of Crohn's disease (CD) patients undergoing early surgery (ES) to those undergoing initial medical therapy (IMT). METHODS: We performed a review of a prospective database CD patients managed at a single tertiary institution. Inclusion criteria were all patients with ileal or ileocolonic CD between 1995-2014. Patients with incomplete data, isolated colonic or perianal CD were excluded. Primary endpoints included the need for, and time to subsequent surgery. Secondary endpoints included the number and duration of hospital admissions, and medical therapy. RESULTS: Forty-two patients underwent ES and 115 underwent IMT. The operative intervention rate at 5 years in the ES group was 14.2% vs IMT 31.3% (HR = 0.41, 95%CI: 0.23-0.72, P = 0.041). The ES group had fewer hospital admissions per patient [median 1 vs 3 (P = 0.012)] and fewer patients required anti-TNF therapy than IMT (33.3% vs 57%, P = 0.003). A subgroup analysis of 62 IMT patients who had undergone surgery were compared to ES patients, and showed similar 5 year (from index surgery) re-operation rates 16.1% vs 14.3%. In this subset, a significant difference was still found in median number of hospital admissions favouring ES, 1 vs 2 (P = 0.002). CONCLUSION: Our data supports other recent studies suggesting that patients with ileocolonic CD may have a more benign disease course if undergoing early surgical intervention, with fewer admissions to hospital and a trend to reduced overall operation rates.
