Cachexia index for prognostication in surgical patients with locally advanced oesophageal or gastric cancer: multicentre cohort study.

BACKGROUND: Features of cancer cachexia adversely influence patient outcomes, yet few currently inform clinical decision-making. This study assessed the value of the cachexia index (CXI), a novel prognostic marker, in patients for whom neoadjuvant chemotherapy and surgery for oesophagogastric cancer is planned. METHODS: Consecutive patients newly diagnosed with locally advanced (T3-4 or at least N1) oesophagogastric cancer between 1 January 2010 and 31 December 2015 were identified through the West of Scotland and South-East Scotland Cancer Networks. CXI was calculated as (L3 skeletal muscle index) × (serum albumin)/(neutrophil lymphocyte ratio). Sex-stratified cut-off values were determined based on the area under the curve (AUC), and patients were divided into groups with low or normal CXI. Primary outcomes were disease progression during neoadjuvant chemotherapy and overall survival (at least 5 years of follow-up). RESULTS: Overall, 385 patients (72% men, median age 66 years) were treated with neoadjuvant chemotherapy for oesophageal (274) or gastric (111) cancer across the study interval. Although patients with a low CXI (men: CXI below 52 (AUC 0.707); women: CXI below 41 (AUC 0.759)) were older with more co-morbidity, disease characteristics were comparable to those in patients with a normal CXI. Rates of disease progression during neoadjuvant chemotherapy, leading to inoperability, were higher in patients with a low CXI (28 versus 12%; adjusted OR 3.07, 95% c.i. 1.67 to 5.64; P < 0.001). Low CXI was associated with worsened postoperative mortality (P = 0.019) and decreased overall survival (median 14.9 versus 56.9 months; adjusted HR 1.85, 1.42 to 2.42; P < 0.001). CONCLUSION: CXI is associated with disease progression, worse postoperative mortality, and overall survival, and could improve prognostication and decision-making in patients with locally advanced oesophagogastric cancer.

Identifying the limitations of cardiopulmonary exercise testing prior to esophagectomy using a pooled analysis of patient-level data.

Preoperative cardiopulmonary exercise testing (CPET) provides an objective assessment of aerobic fitness in patients undergoing surgery. While peak oxygen uptake during exercise (VO2peak) and anaerobic threshold have demonstrated a moderate correlation with the development of complications following esophagectomy, no clinically useful threshold values have been defined. By pooling patient level data from existing studies, we aimed to define optimal thresholds for preoperative CPET parameters to predict patients at high risk of postoperative complications. Studies reporting on the relationship between preoperative CPET variables and post-esophagectomy complications were determined from a comprehensive literature search. Patient-level data were obtained from six contributing centers for pooled-analyses. Outcomes of interest included cardiopulmonary and non-cardiopulmonary complications, unplanned intensive care unit readmission, and 90-day and 12-month all-cause mortality. Receiver operating characteristic curves and logistic regression models estimated the predictive value of CPET parameters for each individual outcome of interest. This analysis comprised of 621 patients who underwent CPET prior to esophagectomy during the period from January 2004 to March 2017. For both anaerobic threshold and VO2peak, none of the receiver operating characteristic curves achieved an area under the curve value > 0.66 for the outcomes of interest. The discriminatory ability of CPET for determining high-risk patients was found to be poor in patients undergoing an esophagectomy. CPET may only carry an adjunct role to clinical decision-making.

Staging the Tumor and Staging the Host: Pretreatment Combined Neutrophil Lymphocyte Ratio and Modified Glasgow Prognostic Score Is Associated with Overall Survival in Patients with Esophagogastric Cancers Undergoing Treatment with Curative Intent.

BACKGROUND: This study examined whether an innate systemic inflammatory response (SIR) measured by combination neutrophil to lymphocyte ratio (NLR) and modified Glasgow Prognostic Score (mGPS) was associated with overall survival (OS) in patients with esophagogastric cancer (EC) undergoing neoadjuvant chemotherapy (NAC) followed by surgery. METHODS: Patients diagnosed with EC, managed with NAC prior to surgery at a regional referral center, between January 2010 and December 2015, were included. The mGPS and NLR were calculated within 12 weeks before NAC. Patients were grouped by combined NLR/mGPS score into three groups of increasing SIR: NLR ≤ 3 (n = 152), NLR > 3 + mGPS = 0 (n = 55), and NLR > 3 + mGPS > 0 (n = 32). Univariable and multivariable Cox regression was used to analyse OS. RESULTS: Overall, 337 NAC patients were included, with 301 (89%) proceeding to surgery and 215 (64%) having R0 resection. There were 203 deaths, with a median follow-up of those alive at censor of 69 months (range 44-114). Higher combined NLR/mGPS score (n = 239) was associated with poorer OS independent of clinical stage and performance status (hazard ratio 1.28, 95% confidence interval 1.02-1.61; p = 0.032), higher rate of progression on NAC (7% vs. 7% vs. 19%; p = 0.003), and lower proportion of eventual resection (80% vs. 84% vs. 53%; p = 0.003). CONCLUSIONS: The combined NLR/mGPS score was associated with OS and initial treatment outcomes in patients undergoing NAC prior to surgery for EC, stratifying survival in addition to clinical staging and performance status. The host SIR may be a useful adjunct to multidisciplinary decision making.

Postoperative C-reactive protein concentrations to predict infective complications following gastrectomy for cancer.

BACKGROUND AND OBJECTIVES: Gastrectomy for gastric cancer is associated with significant infective postoperative complications. C-reactive protein (CRP) is a useful biomarker in the early detection of infective complications following major abdominal surgery. This single-centre retrospective study aimed to determine the relationship between postoperative CRP levels and development of postoperative infective complications after gastrectomy. METHODS: Daily postoperative CRP levels were analyzed to determine a CRP threshold associated with infective complications. ROC curve analysis was used to determine which postoperative day (POD) gave the optimal cutoff. Multivariate analysis was performed to determine significant factors associated with complications. RESULTS: One hundred and forty-four patients were included. A total of 61 patients (42%) had at least one infective complication. A CRP level of 220 mg/L was associated with the highest AUC (0.765) with a sensitivity of 70% and specificity of 76% (positive predictive value, 67%; negative predictive value, 78%). More patients with a CRP > 220 mg/L on POD 3 developed infective complications (67% vs. 21%, p < 0.001). CONCLUSIONS: A CRP of more than 220 mg/L on POD 3 may be useful to alert clinicians to the increased risk of a postoperative infective complication or enable earlier safe discharge from critical care for those with a lower value.

Long-term outcome and quality of life after supercharged jejunal interposition for oesophageal replacement.

BACKGROUND: The consequences of major conduit necrosis following oesophagectomy are devastating. Jejunal interposition with vascular supercharging is an alternative reconstructive method if colon is unavailable. Aims of this study were to review the long-term outcome and quality of life of patients undergoing this surgery in our tertiary unit. METHODS: Patients undergoing oesophageal reconstruction with supercharged jejunum were identified and retrospective review of hospital notes performed. Each patient was then interviewed for follow up data and quality of life assessment using the EORTC QLQ-C30 questionnaire. RESULTS: Six patients (5 men) (median age 59 years (range 34-72) underwent supercharged pedicled jejunal (SPJ) interposition from May 2005-August 2010. Indications for surgery were loss of both gastric and colonic conduits following surgery for oesophageal cancer (n = 4), loss of gastric conduit and previous colectomy (n = 1) and lastly, gastric and colonic infarction in a strangulated paraoesophageal hernia (n = 1). Median time to reconstruction was 12 months [6-15 range]. There were no in-hospital deaths. Median postoperative stay was 46 days [13-118]. Three patients required surgical re-intervention for leak, sepsis and reflux, respectively. Median follow up was 6.5 years [range 7-102 months]. One patient died seven months following surgery due to respiratory complications. On follow up, 5 patients have an enteral diet without supplemental nutrition, maintaining weight and good quality of life scores. CONCLUSIONS: Supercharged jejunal interposition is a suitable alternative conduit for delayed oesophageal replacement in patients with otherwise limited reconstructive options. Good functional outcomes can be achieved despite formidable technical challenges in this group.

Factors associated with early recurrence and death after esophagectomy for cancer.

BACKGROUND: Accurate selection of patients for radical treatment of esophageal cancer is essential to avoid early recurrence and death (ERD) after surgery. We sought to evaluate a large series of consecutive resections to assess factors that may be associated with this poor outcome. METHODS: This was a cohort study including 680 patients operated for esophageal cancer between 2000 and 2010. The poor outcome group comprised 100 patients with tumor recurrence and death within 1 year of surgery. The comparison group comprised 267 long-term survivors, defined as those surviving more than 3 years from surgery. Pathological characteristics associated with poor outcome were analyzed using logistic regression to determine odds ratios (OR) and 95% confidence intervals (CI). RESULTS: On the adjusted model T stage and N stage predicted poor survival, with the greatest risk being patients with locally advanced tumors and three or more involved lymph nodes (OR 10.6, 95% CI 2.8-40.0). Poor differentiation (OR 2.8, 95% CI 1.4-5.5), chemotherapy response (OR 3.6, 95% CI 1.2-10.6), and involved resection margins (OR 2.7, 95% CI 1.2-6.0) were all significant independent prognostic markers in the multivariable model. There was a trend toward worse survival with lymphovascular invasion (OR 2.0, 95% CI 0.9-4.2) and low albumin (OR 1.9, 95% CI 0.8-4.4) but not of statistical significance in the adjusted model. CONCLUSIONS: Esophageal cancer patients with poorly differentiated tumors and three or more involved lymph nodes have a particularly high risk of ERD after surgery. Accurate risk stratification of patients may identify a group who would be better served by alternative oncological treatment strategies.

Persistent elevation of C-reactive protein following esophagogastric cancer resection as a predictor of postoperative surgical site infectious complications.

BACKGROUND: Infectious complications, particularly in the form of anastomotic leaks (ALs) or surgical site infections (SSIs), represent a serious morbidity after esophagogastric cancer resections. Therefore, early detection is of paramount importance. Although markers of the systemic inflammatory response, including C-reactive protein (CRP) and white cell count (WCC), have been used in this regard, their relative predictive value is unclear. The aim of the present study was to examine serial postoperative WCC, albumin, and CRP and their diagnostic accuracy in case of infectious complications. PATIENTS AND METHODS: White cell count, albumin, and CRP were routinely measured postoperatively for 7 days in 136 consecutive patients who had undergone esophagogastric cancer resection. All postoperative complications were recorded. The diagnostic accuracy of the WCC, albumin, and CRP values were analyzed by receiver operating characteristics curve analysis with surgical site and remote infectious complications as outcome measures. RESULTS: Fifty-four (40%) patients developed infectious complications, and 17 of them developed an AL. CRP was significantly higher from postoperative day (POD) 3 onward in those patients who developed an AL. On POD 3, a threshold reading of 180 mg/l was associated with development of an AL, providing a sensitivity of 82% and a specificity of 63%. On POD 4, the same CRP threshold of 180 mg/l provided 71% sensitivity and 83% specificity. CONCLUSIONS: Postoperative CRP measurements on PODs 3 and 4 are clinically useful in predicting surgical site infectious complications, in particular an AL, after resection for esophagogastric cancer.

Perioperative outcomes after transition from conventional to minimally invasive Ivor-Lewis esophagectomy in a specialized center.

BACKGROUND: Minimally invasive techniques are now increasingly adopted for the treatment of esophageal cancers. Benefits such as earlier functional recovery and less need for transfusion and intensive care stay should be balanced by a determination to avoid compromise to the oncologic integrity of the procedure, especially in the early phase of transition from open to laparoscopic surgery. This study aimed to compare primary outcomes including oncologic clearance, complications, and functional recovery between open and laparoscopic esophagectomy in a single center. METHODS: This prospective study recruited 75 consecutive patients undergoing Ivor-Lewis esophagectomy, all treated by a single surgeon. These patients were divided into three groups. The 24 patients in group A underwent open Ivor-Lewis esophagectomy. The remaining patients underwent laparoscopic Ivor-Lewis esophagectomy in two groups: 25 patients in an early cohort (group B) and 26 patients in a later cohort (group C). All the patients were treated according to the same protocol. RESULTS: The three groups were adequately matched. The findings showed trends toward a reduction in median operative time, with group A requiring 260 min, group B requiring 249 min, and group C requiring 223 min (p = 0.06), and a significant reduction in the requirement for perioperative blood transfusion between groups A (65%) and C (27%) (p = 0.02). The median lymph node yield was significantly less in group B (n = 13) than in group A (n = 24) or group C (n = 22) (p = 0.003). There was no significant difference between the three groups in the length of hospital stay (median stay, 14-16 days) or the requirement for critical care beds (median stay, 3-4 days). The in-hospital mortality rate was zero, and the morbidity rate did not differ between the three groups. CONCLUSIONS: This study shows that laparoscopic Ivor-Lewis esophagectomy is associated with a reduced need for blood transfusion, a shorter operative time, and an adequate lymph node harvest. Oncologic principles are not compromised during the transition phase from open to laparoscopic esophagectomy.

Transhiatal esophagectomy in a high volume institution.

BACKGROUND: The optimal operative approach for carcinoma at the lower esophagus and esophagogastric junction remains controversial. The aim of this study was to assess a single unit experience of transhiatal esophagectomy in an era when the use of systemic oncological therapies has increased dramatically. STUDY DESIGN: Between January 2000 and November 2006, 215 consecutive patients (182 males, 33 females, median age = 65 years) underwent transhiatal esophagectomy; invasive malignancy was detected preoperatively in 188 patients. 90 patients (42%) received neoadjuvant chemotherapy. Prospective data was obtained for these patients and cross-referenced with cancer registry survival data. RESULTS: There were 2 in-hospital deaths (0.9%). Major complications included: respiratory complications in 65 patients (30%), cardiovascular complications in 31 patients (14%) and clinically apparent anastomotic leak in 12 patients (6%). Median length of hospital stay was 14 days. The radicality of resection was inversely related to T stage: an R0 resection was achieved in 98-100% of T0/1 tumors and only 14% of T4 tumors. With a median follow up of 26 months, one and five year survival rates were estimated at 81% and 48% respectively. CONCLUSION: Transhiatal esophagectomy is an effective operative approach for tumors of the infracarinal esophagus and the esophagogastric junction. It is associated with low mortality and morbidity and a five survival rate of nearly 50% when combined with neoadjuvant chemotherapy.

Breast cancer metastasis to the stomach may mimic primary gastric cancer: report of two cases and review of literature.

BACKGROUND: The stomach is an infrequent site of breast cancer metastasis. It may prove very difficult to distinguish a breast cancer metastasis to the stomach from a primary gastric cancer on the basis of clinical, endoscopic, radiological and histopathological features. It is important to make this distinction as the basis of treatment for breast cancer metastasis to the stomach is usually with systemic therapies rather than surgery. CASE PRESENTATIONS: The first patient, a 51 year old woman, developed an apparently localised signet-ring gastric adenocarcinoma 3 years after treatment for lobular breast cancer with no clinical evidence of recurrence. Initial gastric biopsies were negative for both oestrogen and progesterone receptors. Histopathology after a D2 total gastrectomy was reported as T4 N3 Mx. Immunohistochemistry for Gross Cystic Disease Fluid Protein was positive, suggesting metastatic breast cancer. The second patient, a 61 year old woman, developed a proximal gastric signet-ring adenocarcinoma 14 years after initial treatment for breast cancer which had subsequently recurred with bony and pleural metastases. In this case, initial gastric biopsies were positive for both oestrogen and progesterone receptors; subsequent investigations revealed widespread metastases and surgery was avoided. CONCLUSION: In patients with a history of breast cancer, a high index of suspicion for potential breast cancer metastasis to the stomach should be maintained when new gastrointestinal symptoms develop or an apparent primary gastric cancer is diagnosed. Complete histopathological and immunohistochemical analysis of the gastric biopsies and comparison with the original breast cancer pathology is important.

Diagnostic peritoneal lavage and ultrasonography for blunt abdominal trauma: attitudes and training of current general surgical trainees.

OBJECTIVE: It has been suggested that diagnostic peritoneal lavage is now obsolete in UK hospitals with access to either skilled ultrasonography or emergency physician or surgeon-performed focused abdominal sonography in trauma. Diagnostic peritoneal lavage continues to be advocated and taught on Advanced Trauma Life Support courses. The aim of this study was to evaluate the experiences and attitudes of general-surgery trainees in one UK training region towards diagnostic peritoneal lavage and focused abdominal sonography in trauma in managing blunt abdominal trauma. METHODS: An anonymous postal piloted questionnaire was sent to all 66 general surgery specialist trainees in one UK training region between January and March 2005. RESULTS: Out of 40 replies to the questionnaire (response rate 61%), 53% and 38% of surgical trainees had either never performed or never observed a diagnostic peritoneal lavage during their training. Thirteen trainees (33%) felt diagnostic peritoneal lavage to be obsolete and would never contemplate using it; 15 trainees (37%) might consider using diagnostic peritoneal lavage if computed tomography or ultrasonography were unavailable. Ten trainees (25%) felt that diagnostic peritoneal lavage had been superseded by computed tomography. Only 12 trainees (30%) had worked in a UK hospital with access to facilities for focused abdominal sonography in trauma and only seven trainees (18%) had received any training or experience in focused abdominal sonography in trauma. CONCLUSIONS: Surgical trainees in one UK training region lack skills in both diagnostic peritoneal lavage and focused abdominal sonography in trauma for managing blunt abdominal trauma and are therefore reliant upon the availability of prompt, skilled radiological assistance or emergency physician-provided focused abdominal sonography in trauma.

Long-term survival from gastrocolic fistula secondary to adenocarcinoma of the transverse colon.

BACKGROUND: Gastrocolic fistula is a rare presentation of both benign and malignant diseases of the gastrointestinal tract. Malignant gastrocolic fistula is most commonly associated with adenocarcinoma of the transverse colon in the Western World. Despite radical approaches to treatment, long-term survival is rarely documented. CASE PRESENTATION: We report a case of a 24-year-old woman who presented with the classic triad of symptoms associated with gastrocolic fistula. Radical en-bloc surgery and adjuvant chemotherapy were performed. She is still alive ten years after treatment. CONCLUSIONS: Gastrocolic fistula is an uncommon presentation of adenocarcinoma of the transverse colon. Radical en-bloc surgery with adjuvant chemotherapy may occasionally produce long-term survival.

Surgical management of Boerhaave's syndrome in a tertiary oesophagogastric centre.

INTRODUCTION: The aim of this study was to review the management and outcome of patients with Boerhaave's syndrome in a specialist centre between 2000-2007. PATIENTS AND METHODS: Patients were grouped according to time from symptoms to referral (early, < 24 h; late, > 24 h). The effects of referral time and management on outcomes (oesophageal leak, reoperation and mortality) were evaluated. RESULTS: Of 21 patients (early 10; late 11), three were unfit for surgery. Of the remaining 18, immediate surgery was performed in 8/8 referred early and 6/10 referred late. Four patients referred late were treated conservatively. Oesophageal leak (78% versus 12.5%; P < 0.05) and mortality (40% versus 0%; P < 0.05) rates were higher in patients referred late. For patients referred late, mortality was higher in patients managed conservatively (75% versus 17%; not significant). CONCLUSIONS: The best outcomes in Boerhaave's syndrome are associated with early referral and surgical management in a specialist centre. Surgery appears to be superior to conservative treatment for patients referred late.

Surgical management of late complications after colonic interposition for esophageal atresia.

Late complications after colonic interposition for neonatal esophageal atresia may lead to debilitating symptoms, poor quality of life, and malnutrition in young adults with otherwise normal life expectancies. We report our experience with 3 patients who underwent revision surgery more than 20 years after colonic interposition. Revision surgery may relieve symptoms and improve quality of life in selected patients. However, for patients with recurrent symptoms, further reconstructive options may be limited due to the lack of an available conduit, and long-term enteral feeding may be the only option for these patients.

Is cardiopulmonary exercise testing a useful test before esophagectomy?

BACKGROUND: Cardiopulmonary exercise (CPX) testing may identify patients at high risk of postoperative cardiopulmonary morbidity and mortality. This study aims to assess the utility of CPX testing before esophagectomy. METHODS: Between January 2004 and October 2006, 78 consecutive patients (64 men) with a median age of 65 years (range, 40 to 81 years) underwent CPX testing before esophagectomy (50% transhiatal; 50% transthoracic). Measured variables included anaerobic threshold (AT) and maximum oxygen uptake at peak exercise (VO2peak). Outcome measures were postoperative morbidity and mortality, length of hospital stay, and unplanned intensive therapy unit admission. RESULTS: Cardiopulmonary complications occurred in 33 (42%) patients and noncardiopulmonary complications in 19 (24%). One in-hospital death (1.3%) occurred, and 13 patients (17%) required an unplanned intensive therapy unit admission. The level of VO2peak was significantly lower in patients with postoperative cardiopulmonary morbidity (p = 0.04). The area under a receiver operating characteristic curve was 0.63 (95% confidence interval [CI], 0.50 to 0.76) for the VO2peak and 0.62 (95% CI, 0.49 to 0.75) for AT. An AT cutoff of 11 mL/kg/min was a poor predictor of postoperative cardiopulmonary morbidity. CONCLUSIONS: Although the VO2peak was significantly lower in those patients who developed cardiopulmonary complications, CPX testing is of limited value in predicting postoperative cardiopulmonary morbidity in patients undergoing esophagectomy.

Recurrent laryngeal nerve palsy due to impacted dental plate in the thoracic oesophagus: case report.

BACKGROUND: Retained oesophageal foreign bodies must be urgently removed to prevent potentially serious complications. Recurrent laryngeal nerve palsy is rare and has not been reported in association with a foreign body in the thoracic oesophagus. CASE PRESENTATION: We present a case of a dental plate in the thoracic oesophagus that caused high dysphagia. Delayed diagnosis led to a recurrent laryngeal nerve palsy, which persisted despite successful surgical removal of the foreign body. CONCLUSION: Oesophagoscopy is essential to fully assess patients with persistent symptoms after foreign body ingestion, irrespective of the level of dysphagia. Recurrent laryngeal nerve palsy may indicate impending perforation and should prompt urgent evaluation and treatment.

Duodenal volvulus: report of a case.

A duodenal volvulus is a hitherto unreported condition caused by an abnormal mobility of the third and fourth parts of the duodenum. We herein report the first such case, including its presentation, management, and possible etiology.

Vomiting-induced pneumomediastinum and subcutaneous emphysema does not always indicate Boerhaave's syndrome: report of six cases.

Spontaneous pneumomediastinum is an uncommon, self-limiting condition resulting from alveolar rupture in young adults. Because of the ambiguous presentation and the general lack of awareness of this condition, its diagnosis is often delayed, missed, or confused with spontaneous esophageal perforation. We report our experience of treating six patients who were referred to our unit with vomiting-induced pneumomediastinum, subcutaneous emphysema, and an initial diagnosis of spontaneous esophageal perforation. Ultimately, we diagnosed spontaneous pneumomediastinum in all six patients, who recovered uneventfully without any surgical intervention. We review the literature with particular emphasis on differentiating spontaneous pneumomediastinum from spontaneous esophageal perforation.

Surveillance and conservative management of a persistent sciatic artery aneurysm.

A persistent sciatic artery aneurysm is a rare congenital vascular anomaly. Surgical intervention is reserved for symptomatic cases. The authors report the case of a 72-year-old woman who presented with thromboembolic occlusion of an aneurysmal persistent sciatic artery. Although initially symptomatic, she was managed expectantly with the aid of serial duplex sonographic imaging. The persistent sciatic artery subsequently thrombosed as a result of hypotension secondary to a myocardial infarction. No surgical intervention was required. The current literature on this condition is reviewed.

Endoscopic transanal rectal mucosal ablation in the surgical treatment of ulcerative colitis: preliminary results of a novel technique.

PURPOSE: We describe a new technique that endoscopically eradicates rectal stump mucosa after total colectomy for ulcerative colitis. METHODS: Seven patients (5 males; median age, 56 (range, 36-72) years) underwent attempted endoscopic transanal rectal mucosal ablation using the 28-French-gauge urologic resectoscope, either at the time of total colectomy and ileostomy for failed medical therapy (5 patients) or as an alternative to completion proctectomy (2 patients) with rectal stump discharge. All had declined restorative proctocolectomy. Clinical, endoscopic, and histologic follow-up was undertaken during a mean of 15 (range, 3-28) months. RESULTS: The operative technique evolved during these cases; mucosal ablation was successfully performed leaving a denuded muscular rectal tube in situ in six patients. Mean operative time was 45 minutes. Postoperative endoscopic surveillance has not demonstrated any viable rectal mucosa in these six patients, with only granulation tissue detected histologically. Narrowing of the rectal tube has occurred in two patients. Although all patients report insignificant rectal discharge, urinary and sexual function have remained unchanged. CONCLUSIONS: Diathermy ablation of the rectal mucosa via endoscopic transanal rectal mucosal ablation avoids the complications of pelvic dissection and might offer an effective alternative to proctectomy for ulcerative colitis.
