RESUMEN
BACKGROUND: Synchronous colon cancers, defined as two or more primary colon cancer detected simultaneously at the time of initial diagnosis, account for up to 5% of all colon cancer diagnoses. Management principles and outcomes remain largely undefined. METHODS: A retrospective institutional review of patients undergoing curative intent resection for colon adenocarcinoma (Stages I-III) from 1995 to 2007 was performed. Hereditary causes or inflammatory bowel disease were excluded. Matching was performed and Kaplan-Meier analysis was used to compare overall survival. RESULTS: Of 2,387 patients, 100 (4.2%) had synchronous cancers. Patients with synchronous lesions tended to be older (median 77 vs. 72 years, P < 0.001) with more advanced tumors (41.0% vs. 31.4% Stage III, P = 0.04). After matching, there were no differences in demographics or tumor factors (all P > 0.05). Compared to solitary, synchronous cancers demonstrated an inferior 10-year overall survival (53.9% vs. 36.5%, P = 0.009). Subset analysis of patients with synchronous cancers showed no difference in overall survival between those with extended versus segmental resections at 120-months (P = 0.07). CONCLUSION: Synchronous colon cancer is associated with decreased overall survival compared to patients with solitary tumors. Extended resection does not confer a survival benefit in these patients. Further research is needed to determine how to mitigate the poor outcomes. J. Surg. Oncol. 2016;114:80-85. © 2016 Wiley Periodicals, Inc.

BACKGROUND: Local excision is an organ-preserving treatment alternative to transabdominal resection for patients with stage I rectal cancer. However, local excision alone is associated with a high risk of local recurrence and inferior survival compared with transabdominal rectal resection. We investigated the oncological and functional outcomes of neoadjuvant chemoradiotherapy and local excision for patients with stage T2N0 rectal cancer. METHODS: We did a multi-institutional, single-arm, open-label, non-randomised, phase 2 trial of patients with clinically staged T2N0 distal rectal cancer treated with neoadjuvant chemoradiotherapy at 26 American College of Surgeons Oncology Group institutions. Patients with clinical T2N0 rectal adenocarcinoma staged by endorectal ultrasound or endorectal coil MRI, measuring less than 4 cm in greatest diameter, involving less than 40% of the circumference of the rectum, located within 8 cm of the anal verge, and with an Eastern Cooperative Oncology Group performance status of at least 2 were included in the study. Neoadjuvant chemoradiotherapy consisted of capecitabine (original dose 825 mg/m(2) twice daily on days 1-14 and 22-35), oxaliplatin (50 mg/m(2) on weeks 1, 2, 4, and 5), and radiation (5 days a week at 1·8 Gy per day for 5 weeks to a dose of 45 Gy, followed by a boost of 9 Gy, for a total dose of 54 Gy) followed by local excision. Because of adverse events during chemoradiotherapy, the dose of capecitabine was reduced to 725 mg/m(2) twice-daily, 5 days per week, for 5 weeks, and the boost of radiation was reduced to 5·4 Gy, for a total dose of 50·4 Gy. The primary endpoint was 3-year disease-free survival for all eligible patients (intention-to-treat population) and for patients who completed chemotherapy and radiation, and had ypT0, ypT1, or ypT2 tumours, and negative resection margins (per-protocol group). This study is registered with ClinicalTrials.gov, number NCT00114231. FINDINGS: Between May 25, 2006, and Oct 22, 2009, 79 eligible patients were recruited to the trial and started neoadjuvant chemoradiotherapy. Two patients had no surgery and one had a total mesorectal excision. Four additional patients completed protocol treatment, but one had a positive margin and three had ypT3 tumours. Thus, the per-protocol population consisted of 72 patients. Median follow-up was 56 months (IQR 46-63) for all patients. The estimated 3-year disease-free survival for the intention-to-treat group was 88·2% (95% CI 81·3-95·8), and for the per-protocol group was 86·9% (79·3-95·3). Of 79 eligible patients, 23 (29%) had grade 3 gastrointestinal adverse events, 12 (15%) had grade 3-4 pain, and 12 (15%) had grade 3-4 haematological adverse events during chemoradiation. Of the 77 patients who had surgery, six (8%) had grade 3 pain, three (4%) had grade 3-4 haemorrhage, and three (4%) had gastrointestinal adverse events. INTERPRETATION: Although the observed 3-year disease free survival was not as high as anticipated, our data suggest that neoadjuvant chemoradiotherapy followed by local excision might be considered as an organ-preserving alternative in carefully selected patients with clinically staged T2N0 tumours who refuse, or are not candidates for, transabdominal resection.

Multimodal fast-track (FT) pathways for both open and laparoscopic colorectal surgery have been shown to improve gastrointestinal recovery, shorten length of stay, and decrease morbidity. The aim of our study was to determine if using alvimopan (Entereg)™ in the setting of a FT minimally invasive colorectal pathway is beneficial and cost-effective. All minimally invasive colorectal surgeries performed by one surgeon using a multimodal FT pathway with and without alvimopan were reviewed. Ninety total patients were identified, 64 patients treated without and 26 with alvimopan. Main outcomes included postoperative day tolerating a soft diet, return of gastrointestinal function, length of stay, 30-day readmission rate, and patient care, anesthesia, pharmacy, and combined cost. Tolerance of a soft diet, return of gastrointestinal function, and length of stay were all shorter and showed significance in the alvimopan group (mean 2.1 vs 2.8 days, mean 1.5 vs 2.4 days, and mean 3.5 vs 4.5 days, respectively) (P = 0.0197, P = 0.0029, and 0.0158, respectively). Patient care and combined hospital costs were both increased in the nonalvimopan group; however, combined hospital costs was not significant (P = 0.0216 and P = 0.0875, respectively). The 30-day readmission rate of 6.3 per cent was also not significant in this group (P = 0.0941). Patients undergoing minimally invasive colorectal surgery treated with a multimodal FT pathway tolerated a soft diet sooner, had earlier return of bowel function, a shorter length of stay, and lower patient care and combined costs when alvimopan was used.

BACKGROUND: Patients with chronic ulcerative colitis are at increased risk of developing colorectal cancer. Limited data exists in ulcerative colitis patients with rectal cancer regarding clinical and oncologic outcomes, and the ideal operative approach. OBJECTIVE: To describe our experience in the management of patients with rectal cancer in the setting of chronic ulcerative colitis and their outcomes. DESIGN: This study is a retrospective review of all patients with ulcerative colitis who underwent a colorectal operation between 1990 and 2009. SETTINGS: This study was conducted at a tertiary care center. PATIENTS: Adult patients with rectal adenocarcinoma undergoing a colorectal operation for chronic ulcerative colitis were included in this study. Patients with colonic malignancy, indeterminate colitis, and Crohn's disease were excluded. MAIN OUTCOME MEASURES: Clinical features and long-term oncologic outcomes are described. RESULTS: Forty-one patients were identified; their mean age was 53.9 years. Mean duration of ulcerative colitis was 22.5 years. Thirty-four patients (83%) were known to have cancer preoperatively; in 7 patients it was discovered on postoperative pathology. Eight of the tumors were in the proximal rectum, 19 in the mid rectum, and 13 in the distal rectum. The most common operation performed was total proctocolectomy with end ileostomy (n = 21), followed by IPAA. The majority of patients (n = 28, 68%) had stage I or II disease. Estimates of overall survival at 1 and 5 years were 83% and 62%, and, for disease-free survival, the estimates were 93% and 62%. Local and distant recurrence was seen in 5 and 9 patients. Eighty-nine percent of the observed recurrences were in patients with stage III and IV disease. Pouch failure occurred in 2 patients. LIMITATIONS: This retrospective study was possibly underpowered, given the small sample sizes. CONCLUSION: In our cohort, rectal cancer in the setting of chronic ulcerative colitis was rare, often presented at an early stage, and was not always diagnosed preoperatively. The presence of early-stage rectal cancer should not be considered a contraindication for IPAA.

INTRODUCTION: The classification of complicated and uncomplicated diverticulitis has been used for many years. We note variations in the course of uncomplicated diverticulitis. We propose and describe three categories of uncomplicated diverticulitis. METHODS: A review was performed on 907 patients who underwent sigmoid resection for diverticulitis between January 1, 2005 and December 30, 2009 at Mayo Clinic, Rochester. Overall, 223 individuals were excluded as they were not uncomplicated diverticulitis. The remaining 684 patients were divided into three classifications as follows: 54 (7.9 %) atypical, 66 (9.6 %) chronic/smoldering, and 564 (82 %) acute resolving. Data elements abstracted included demographics, preoperative symptoms, imaging and endoscopy, operative and pathologic findings, postoperative complications, and resolution of symptoms. RESULTS: The 30-day complication rate of the atypical, chronic/smoldering, and acute groups was 26 %, 22 %, and 35 %, respectively. Resolution of symptoms for the atypical and chronic/smoldering groups was 93 % and 89 %, respectively. Only two patients in the acute resolving group required an operation for recurrence. CONCLUSION: A spectrum of clinical presentation for uncomplicated diverticulitis may require different approaches. A select group of patients with chronic/smoldering and atypical disease will continue to be burdened by symptoms. The success of surgical intervention was greater than 89 % in both groups with acceptable morbidity, and should remain an option.

The classifications of acute uncomplicated diverticulitis and complicated diverticulitis have served us well for many years. However, in recent years, we have noted the prevalence of variations of uncomplicated diverticulitis, which have not precisely fit under the classification of 'acute resolving uncomplicated diverticulitis', which manifests itself with the typical left lower quadrant pain, fever, diarrhea, elevated white blood count, and CT findings, such as stranding, and which resolves fairly promptly and completely on oral antibiotic therapy. For these other variations, we would suggest we use the term chronic diverticulitis, as a subset of uncomplicated diverticulitis, meaning there is no abscess, stricture, or fistula, but the episode does not respond to the usual antibiotic treatment, and there is a rebound symptomatology once the treatment has stopped, or there is continuing subliminal inflammation that continues, typically, for several weeks after the initial episode without complete resolution. This variation could also be termed 'smoldering' diverticulitis. A second variation of uncomplicated diverticulitis should be termed atypical diverticulitis, since this variant does not manifest all of the usual components of acute diverticulitis, particularly an absence of fever, and even white blood count elevation, and there may be a lack of diagnostic evidence of acute diverticulitis. This diagnosis must be compared with diarrhea-predominant irritable bowel syndrome, and it is sometimes very difficult to distinguish between these two entities. The character of the pain in irritable bowel syndrome is typically cramping intermittently, compared with the more constant pain in smoldering diverticulitis. In our study by Horgan, McConnell, Wolff and coworkers, 5% of 930 patients who underwent sigmoid resection fit into this category of atypical uncomplicated diverticulitis. These 47 patients all had diverticulosis, and 76% that had surgery had evidence of acute and chronic inflammation, and 15% had an unsuspected pericolonic abscess. There was no mortality and a low complication mortality rate (4.2%). Complete resolution of symptoms was achieved in 76.5 with 80% being pain free. Therefore, this is mostly a diagnosis of exclusion, and clinicians must be careful to perform a thorough workup and evaluation before proceeding to surgery with this as a diagnosis. Ischemic colitis is also in the differential diagnosis, and many patients who have diverticulitis, have irritable bowel syndrome as well, so caution must be used in predicting positive outcomes after surgery in these patients.

BACKGROUND: Colorectal surgery is associated with high rates of surgical site infection (SSI). The National Surgery Quality Improvement Program is a validated, risk-adjusted quality-improvement program for surgical patients. Patient stratification and risk adjustment are associated with Current Procedural Terminology codes and primary disease diagnosis is not considered. Our aim was to determine the association between disease diagnosis and SSI rates. METHODS: Data from all 2009 National Surgery Quality Improvement Program institutions were analyzed. ICD-9 codes were used to differentiate patients into cancer (colon or rectal), ulcerative colitis, regional enteritis, diverticular disease, and others. Diagnosis-specific SSI rates were compared with benign neoplasm, which had the lowest rate (8.9%). Logistic regression was performed adjusting for age, body mass index, American Society of Anesthesiologists classification, wound type, and relative value unit. RESULTS: There were 24,673 colorectal procedures, with 1,956 superficial incisional (SSSI), 398 deep incisional (DSSI), and 1,096 organ/space (O/SSSI) infections. Odds ratio (OR) and 95% confidence intervals compared with benign neoplasm diagnosis were computed after adjustment for each diagnosis category. In rectal cancer patients, significantly more SSSI (OR = 1.6; 95% CI, 1.3-2.1; p < 0.0001), DSSI (OR = 2.1; 95% CI, 1.3-3.7; p = 0.006), and O/SSSI (OR = 2.2; 95% CI, 1.6-3.0; p < 0.0001) developed. In diverticular patients, more SSSI (OR = 1.6; 95% CI, 1.3-2.0; p < 0.0001), but not DSSI or O/SSSI, developed. In ulcerative colitis patients, more DSSI (OR = 2.4; 95% CI, 1.2-4.9; p = 0.01), O/SSSI (OR = 2.1; 95% CI, 1.4-3.1; p = 0.0004), but fewer SSSIs, developed. CONCLUSIONS: We found that SSI type is associated with the underlying disease diagnosis. To facilitate colorectal SSI-reduction efforts, the disease process must be considered to design appropriate interventions. In addition, institutional comparisons based on aggregate or stratified SSI rates can be misleading if the colorectal disease mix is not considered.

BACKGROUND: Permanent colostomy, pelvic dissection, and radiotherapy after abdominoperineal resection can put quality of life and sexual and urinary function at risk; however, there are limited data using validated instruments on patients undergoing abdominoperineal resection regarding these outcome measures. OBJECTIVE: We evaluated the quality of life and the sexual and urinary function of patients undergoing abdominoperineal resection for rectal cancer and compared the outcomes of patients who received and did not receive pre- or postoperative pelvic radiotherapy. METHODS: European Organization for Research and Treatment of Cancer Quality of Life Questionnaires C30 and CR38, International Consultation on Incontinence Questionnaire, American Urological Association Symptom Index, Brief Sexual Function Inventory for men, and sexual function module of the Cancer Rehabilitation Evaluation System for women were mailed to 219 patients who underwent abdominoperineal resection between 1994 and 2004. RESULTS: One-hundred forty-three patients responded (response rate, 65%), of whom 55 (38%) were treated with surgery alone and 88 (62%) received pelvic radiotherapy. Generic and disease-specific quality of life and sexual and urinary function were similar between patients not receiving and receiving pelvic radiotherapy. However, a proportion of patients experienced adverse quality of life after surgery, and this was associated with a younger age, male sex, and sexual inactivity. In sexually active men, sexual function after abdominoperineal resection was diminished compared with population-based controls. LIMITATIONS: This study was limited by the lack of baseline data and cross-sectional nature of survey. CONCLUSIONS: Quality of life and sexual function can be impaired after abdominoperineal resection, although the impact of pelvic radiotherapy appears to be limited. Indication and timing of radiotherapy should be based on oncological indications, but quality of life and functional outcomes should be considered when counseling patients.

BACKGROUND: This study evaluated the impact of tumor regression grading (TRG) and other pathologic variates in a cohort of rectal carcinoma patients treated with neoadjuvant chemoradiotherapy (CRT). The value of a grading less than pCR for predicting survival is unknown. Tumor budding has not been systematically studied in rectal cancer after neoadjuvant therapy. METHODS: Pathologic risk factors for survival were evaluated on surgical specimens of 237 patients with stages I, II, and III rectal cancer treated between 1996 and 2006. All patients underwent preoperative CRT followed by surgical resection 6-8 weeks later. TRG, tumor grade, budding, venous invasion, radial margin, and nodal status were evaluated. The prognostic value of TRG categories was calculated with Cox regression models and validated with resampling methods. RESULTS: TRG of <25% occurred in 61 (25.7%) and a complete response in 39 (16.4%) of the resected specimens. TRG of <25% was shown to be a statistically significant predictor for cancer-specific survival (CSS) and recurrence-free survival (RFS) compared to TRG ≥25% (P = 0.013). Tumor budding was present in 24 (10.1%) of the patients and was negatively associated with CSS (P = 0.013). Lymph node involvement was observed in 83 (35.0%) patients. TRG and nodal status (P < 0.001) were the most significant predictors associated with outcome. CONCLUSION: Partial pathologic response ≥25% was a superior predictor compared to pCR for improved survival after preoperative CRT. CSS and RFS were adversely affected by the presence of lymph node metastases.

PURPOSE: Primary coloduodenal fistula (CDF) is a rare entity. We review our experience with the management and outcomes of CDF. METHODS: This is a retrospective review from 1975 to 2005 of patients with primary CDF. Patients were followed through clinic visits and mail correspondence with a mean (±SE) follow-up of 56 ± 14 months. RESULTS: Twenty-two patients were diagnosed at a mean age of 54 ± 3 years with primary CDF: benign (n = 14) or malignant (n = 8). Benign CDF were due to Crohn's disease (n = 9) or peptic ulcer disease (n = 5); malignant CDF was primarily due to colon cancer (n = 7) plus 1 patient with lymphoma. Indications for operative intervention included intractable symptoms (n = 15), gastrointestinal bleeding (n = 14), and to rule out malignancy (n = 8). Complete resection of malignant CDF with negative margins was achieved in half of patients after en bloc resection. Palliative bypass was performed in those patients with unresectable disease. Thirteen patients with benign CDF had resection of the fistula-2 of these patients required a duodenal bypass. There were no perioperative deaths, and the morbidity rate was 38%. Median survival for patients with malignant CDF was 20 months (range 1-150 months). Two patients with malignant CDF had >5-year survival. All patients with benign CDF who underwent fistula resection had resolution of fistula-related symptoms with one recurrence. CONCLUSION: Benign CDF is amenable to operative therapy with resolution of symptoms and a low recurrence rate. Complete resection of malignant CDF can impart survival benefit.

BACKGROUND: Despite its introduction in 1991, laparoscopic colectomy is performed in <10% of United States patients requiring colectomy. Laparoscopic colectomy is avoided principally because of its technical difficulty, steep learning curve, and increased operative times. Hand-assisted laparoscopic colectomy is an alternative technique that addresses these problems while preserving the short-term benefits of laparoscopic colectomy. OBJECTIVE: To describe the utility and short-term outcomes, we evaluated 1103 patients who underwent hand-assisted laparoscopic colorectal resections over a 5-year period. DESIGN: This study was a retrospective analysis of prospectively collected data. SETTINGS: The setting was a single tertiary care institution. PATIENTS: A total of 1103 consecutive hand-assisted laparoscopic colorectal resections from 2004 to 2009 were identified using a prospectively maintained database. MAIN OUTCOME MEASURES: Demographics, perioperative variables, and 30-day outcomes were reported. Data are presented as frequency (proportion) or median (interquartile range). RESULTS: A total of 1103 hand-assisted laparoscopic colorectal resections were documented. Median age of patients was 55 years; 47% were women, and median body mass index was 26.5 (range, 23-34) kg/m. Diagnoses included inflammatory bowel disease (35%), colorectal cancer (31%), diverticular disease (23%), and "other" (11%). Forty-two percent of patients had prior abdominal surgery. Segmental colectomies were performed in 533 (48%) patients, proctocolectomy with ileal pouch-anal anastomosis in 229 (21%), proctocolectomy with end ileostomy in 114 (10%), and "other" in 227 (21%). The conversion rate was 9%. Overall median operative time was 201 (range, 145-269) minutes, and the median postoperative length of stay was 5 (range, 4-7) days. Postoperative complications occurred in 27% and readmissions in 7%; mortality was 0.3%. LIMITATIONS: This was a single institutional retrospective study. CONCLUSIONS: Hand-assisted laparoscopic colorectal resection can be performed for numerous indications. It preserves nearly all the benefits of laparoscopic colectomy reported in the literature. With experience, it is associated with significantly reduced operative times. Wider adoption of hand-assisted laparoscopic colorectal surgery would increase the number of patients benefiting from minimal access colorectal surgery.

BACKGROUND: The objectives were to determine the feasibility of combined rectal and hepatic resections and analyze the disease-free survival and overall survival. STUDY DESIGN: Sixty patients who underwent resection for metastatic rectal disease from 1991 to 2005 at Mayo Clinic were reviewed. Inclusion criteria were: rectal cancer with metastatic liver disease and resectability of metastases. The exclusion criteria were: metachronous resection (n = 15). Kaplan-Meier Survival estimated overall survival (OS) and disease-free survival (DFS). Cox proportional hazard models examined the association between groups and survival. RESULTS: The cohort comprised 22 men and 23 women, with median age of 63 years. Surgical management included: abdominoperineal resection, 13 patients (29%); low anterior resection, 29 (64%); local excision, one; total proctocolectomy, one; and pelvic exenteration, one. Major hepatic resection was performed in 22%. There was no mortality, but there were 26 postoperative complications. Disease-free survival from local recurrence at 1, 2, and 5 years was 92%, 86%, and 80%, respectively. Disease-free survival from distant recurrence at 1, 2, and 5 years was 62%, 43%, and 28%, respectively. Overall survival at 1, 2 and 5 years was 88%, 72%, and 32%, respectively. CONCLUSIONS: Combined rectal and hepatic resection is safe. Morbidity and mortality do not preclude concurrent resection. The DFS and OS are comparable to that of patients undergoing a staged procedure.

BACKGROUND: Primary sclerosing cholangitis occurs in approximately 10% of patients with ulcerative colitis, but studies involving IPAA in patients with cholangitis have been reported in limited numbers. OBJECTIVE: This study aimed to examine surgical outcomes in patients with ulcerative colitis and sclerosing cholangitis undergoing total proctocolectomy with IPAA and to identify variables associated with surgical complications. DESIGN: This is a retrospective cohort study. SETTINGS: This study was conducted at a single tertiary referral institution. PATIENTS: Included were all patients with cholangitis and ulcerative colitis who underwent proctocolectomy with IPAA from 1994 to 2005. MAIN OUTCOME MEASURES: Perioperative morbidity, long-term pouch function, and pouch survival were the main outcome measures. RESULTS: One hundred patients (62 male) were studied. Forty-three percent were on steroids. There was no perioperative mortality, and 51 30-day complications occurred in 39 patients (39%). Median follow-up time was 5.9 years (range, 0.14-16.2 y). Pouch failure occurred in 3 patients (3%). The single variable that predicted 30-day morbidity was previous abdominal surgery (P = .03). Prednisone use, body mass index, age, ASA score, preoperative Model for End Stage Liver Disease score, and year of surgery were not significantly associated with short-term complications. CONCLUSIONS: IPAA can be performed safely in the setting of sclerosing cholangitis. The preoperative Model for End-stage Liver Disease Score and the use of preoperative immunosuppressive agents are not associated with an increased risk of complications. The likelihood of long-term pouch survival is excellent.

BACKGROUND: Primary intestinal lymphoma in the setting of inflammatory bowel disease (IBD) is uncommon and may be associated with immune suppressive therapy. We report clinical features and outcomes in patients with both conditions prior to use of biologic therapy. METHODS: All patients with primary intestinal lymphoma and IBD at our institution from 1960-2000 were retrospectively identified. Data reported are frequency (proportion) or median (interquartile range). Kaplan-Meier analysis was performed. RESULTS: Fifteen patients were identified: 14 (93%) were male, 10 (66%) had Crohn's disease. Median age at diagnosis of IBD and lymphoma was 30 (22-51) and 47 (28-68) years, respectively, with bloody diarrhea the most common presenting symptom for each diagnosis. Lymphoma location was colorectal in nine (60%), small bowel in four (27%), and one (6.25%) each: stomach, duodenum, and ileal pouch. Treatments were surgery plus chemotherapy (n = 6), surgery alone (n = 3), chemotherapy alone (n = 2), chemotherapy and radiation (n = 1), surgery and radiation (n = 1); two patients died before treatment. Most patients (n = 11, 73%) were Ann Arbor stages I or II. Large cell B-type histology was most common (n = 9, 60%). Three patients died within 30 days of lymphoma diagnosis. Survival free of death from lymphoma at 1- and 5-years was 78% and 63%, respectively, and was associated with advanced lymphoma stage (P = 0.004). CONCLUSIONS: Diagnosis and treatment of primary intestinal lymphoma in patients with IBD can be challenging and requires a high index of suspicion. Optimal survival requires multimodality therapy.

PURPOSE: We assessed risk factors for splenic injury during colectomy and associated outcomes for a 15-year period at a single institution. METHODS: All adult general surgery patients who sustained a splenic injury during colectomy at our institution from 1992 to 2007 were retrospectively identified and matched 1:1 to controls without splenic injury. Putative risk factors were assessed using paired univariate analysis and conditional logistic regression. Differences in short- and long-term mortality were assessed using the log-rank test. Results are reported as a proportion, median, or odds ratio [OR (95% confidence intervals)]. RESULTS: A total of 118 patients were included: 59 patients with splenic injury and 59 control patients. Statistically significant risk factors for splenic injury during colectomy found on univariate analysis included: splenic flexure mobilization, OR 21.00 (2.82-156.12); Charlson comorbidity index≥5, OR 3.17 (1.26-7.93); ASA class≥3, OR 5.33 (1.55-18.3); and nonelective surgery, OR 5.00 (1.1-22.82). On multivariate analysis, only splenic flexure mobilization was independently associated with increased risk of splenic injury (OR 18.4 (2.1-161); p=0.0085). Splenic injured patients trended toward decrease survival both at 30 days (98 vs. 88%; p=0.06) and at 5 years (58 vs. 55%), with a hazard ratio of 1.6 (1.0, 2.6; p=0.05). CONCLUSIONS: Splenic flexure mobilization is the primary risk factor for splenic injury during colectomy, independent of other factors, such as higher ASA class, Charlson score, and nonelective surgery. Splenic injury during colectomy has an increased risk of death in both the short- and long-term.

BACKGROUND: There have been numerous studies with conflicting results regarding the use of anti-tumor necrosis factor (TNF) therapy and its relationship to postoperative outcome in Crohn disease. The aim of our study was to examine the rate of postoperative morbidity in patients receiving anti TNF therapy in the perioperative period. METHODS: All patients undergoing surgery for Crohn disease from 2005 till 2008 were abstracted from a prospective database. Patients undergoing surgery which included a suture or staple line at risk for leaking were selected for the study. A retrospective review of medical records was performed. The study group comprised patients treated with perioperative anti TNF therapy (defined as treatment within 8 weeks preoperatively or up to 30 days postoperatively). The remainder of the patients did not receive perioperative anti TNF therapy. Patient characteristics, disease severity, medication use, operative intervention and 30-day complication were compared between the two groups. RESULTS: Three hundred and seventy patients were selected for analysis in this study, of which 119 received perioperative anti TNF therapy and 251 did not. The groups were similar in baseline characteristics, perioperative risk factors and procedures. The group who received perioperative anti TNF therapy had a more severe disease overall as measured by the American College of Gastroenterology (ACG) categories of disease (50% severe fulminant disease in the perioperative anti-TNF therapy group versus 18% in the group that did not receive perioperative anti-TNF therapy, p < 0.001). There was no significant association of perioperative anti TNF therapy and any postoperative complications (27.9% in anti-TNF group versus 30.1% in no anti-TNF group, p = 0.63) nor intra-abdominal infectious complications (5.0% in anti-TNF group versus 7.2% in no anti-TNF group, p = 0.44). Univariate analysis showed that the only factors associated with an increase in postoperative intra-abdominal infections were age and penetrating disease. CONCLUSIONS: The use of anti-TNF therapy in the perioperative period is safe and is not associated with an increase in overall or infectious complications in Crohn disease patients undergoing surgery.

Patients with Peutz-Jeghers syndrome (PJS) require lifelong multidisciplinary care for gastrointestinal polyposis and increased risk of cancer. Their long-term morbidities and causes of mortality are unknown. Patients with a definitive diagnosis of PJS (n = 54) were retrospectively reviewed for disease course and outcome. Operative details, pathology and complications were noted for those treated surgically (n = 33). Median follow-up was 7.0 years (interquartile range: 2-20). Two malignancies were found intra-operatively (duodenal and rectal adenocarcinoma). In the long-term, 42% underwent additional operations; 1 patient developed short bowel syndrome, while another, chronic partial bowel obstruction and pain. Twenty-one additional cancers were treated in 19 patients: gynecologic (11), lung (3), and prostate (2) being the most common. 16 patients (30%) were deceased, at a median age of 51 years. The cause of death was unknown in 4 patients, but was due exclusively to malignancies in all other patients, most commonly due to metastatic gynecologic cancer (5). The overall survival of PJS patients was significantly shorter than the expected survival of an age-and gender-matched reference population (P < 0.001). Given the morbidities associated with repeated operations and the risk for cancer-related mortality in the long-term, efforts should focus on minimizing the need for surgical intervention and optimizing cancer detection, treatment and prevention.

BACKGROUND: A pooled post hoc responder analysis was performed to assess the clinical benefit of alvimopan, a peripherally acting mu-opioid receptor (PAM-OR) antagonist, for the management of postoperative ileus after bowel resection. METHODS: Adult patients who underwent laparotomy for bowel resection scheduled for opioid-based intravenous patient-controlled analgesia received oral alvimopan or placebo preoperatively and twice daily postoperatively until hospital discharge or for 7 postoperative days. The proportion of responders and numbers needed to treat (NNT) were examined on postoperative days (POD) 3-8 for GI-2 recovery (first bowel movement, toleration of solid food) and hospital discharge order (DCO) written. RESULTS: Alvimopan significantly increased the proportion of patients with GI-2 recovery and DCO written by each POD (P < 0.001 for all). More patients who received alvimopan achieved GI-2 recovery on or before POD 5 (alvimopan, 80%; placebo, 66%) and DCO written before POD 7 (alvimopan, 87%; placebo, 72%), with corresponding NNTs equal to 7. CONCLUSIONS: On each POD analyzed, alvimopan significantly increased the proportion of patients who achieved GI-2 recovery and DCO written versus placebo and was associated with relatively low NNTs. The results of these analyses provide additional characterization and support for the overall clinical benefit of alvimopan in patients undergoing bowel resection.
