Aim: The optimal extent of resection for splenic flexure adenocarcinoma remains debated. These tumours straddle the left‐ and right‐sided vasculature with lymphatic drainage in a watershed area; current guidelines recommend either segmental or extended colectomy. We analysed surgical management of splenic flexure tumours and compared outcomes between approaches. Method: The Surveillance, Epidemiology and End Results database was searched for adults with Stage I–III splenic flexure adenocarcinoma, 2004–2019. Results: Of 5238 patients, 55% underwent extended colectomy. Compared to segmental colectomy, these patients were more likely to have advanced stage. On multivariable analysis, age ≤ 65 years remained independently associated with extended colectomy. Although fewer nodes were examined in segmental colectomy (median 14 vs. 16, p < 0.001), the number of positive nodes (both, median 0 [interquartile ratio 0–2], p = 0.20) and the lymph node ratio were similar between cohorts. Surgical approach was not significantly associated with increased positive nodal yield in adjusted analyses. Five‐year overall and disease‐specific survival were 73% and 84% for segmental and 72% and 83% for extended colectomy (p > 0.4); these remained comparable after adjustment. Conclusions: Nationally, we observed similar rates of segmental and extended colectomy for splenic flexure adenocarcinoma. Extended colectomy was not more common in Stage III disease, indicating lack of stage migration, and was not associated with better oncological outcomes. These observations support current practice involving either approach, which should be tailored to patient‐related factors and preferences, while considering technical aspects and quality of life.

Background: Colorectal cancer is among the most common cancers in the world, and splenic flexure colon cancer accounts for about 2-5% of them. There is still no consensus on the surgical treatment of splenic flexure colon cancer (SFCC), and the extent of surgical resection and lymph node dissection for SFCC is still controversial. Aim: To compare the postoperative and long-term oncologic outcomes of extended right colectomy (ERC), segmental colectomy (SC) and left colectomy (LC) for SFCC. Method: Up to March 2024, retrospective and prospective studies of ERC, SC, and LC for SFCC were searched through databases. Pooled weighted/ standardized mean difference (WMD/SMD), odds ratio (OR) and hazard ratio (HR) with 95% confidence interval (CI) were calculated using a fixed effects model or random effects model, and meta-analysis was performed using Stata. Results: This meta-analysis includes 5,918 patients from 13 studies with more lymph node harvest (OR:6.29; 95%Cl: 3.66-8.91; Z=4.69, P=0), more operation time (WMD: 22.53; 95%Cl: 18.75-26.31; Z=11.68, P=0), more blood loss (WMD:58.44; 95%Cl: 20.20-96.68; Z=2.99, P=0.003), longer hospital stay (WMD:1.74; 95%Cl: 0.20-3.29; Z=2.21, P=0.03), longer time to return to regular diet (WMD:3.17; 95%Cl: 2.05-4.30; Z=5.53, P=0), longer first flatus time (WMD:1.66; 95%Cl: 0.96-2.37; Z=4.61, P=0) in ERC versus SC. More lymph node harvest (WMD: 3.52; 95% Cl: 1.59-5.44; Z=3.58, P=0) in ERC versus LC and LC versus SC (WMD: 1.97; 95% CI: 0.53-3.41; Z=2.68, P=0.007), respectively. There is no significant difference between anastomotic leakage, postoperative ileus, total postoperative complication, severe postoperative complication, wound infection, reoperations, R0 resection, postoperative mortality, 5-year overall survival (OS), 5-year disease-free survival (DFS) in three group of patients. In LC versus SC and ERC versus LC, there is no difference between operation time, blood loss, hospital stay, return to regular diet, and first flatus. Conclusion: In the included studies, SC and LC may be more advantageous, with fewer postoperative complications and faster recovery. ERC harvests more lymph nodes, but there is no significant difference in long-term OS and DFS between the three surgical approaches. Given that the included studies were retrospective, more randomized controlled trials are needed to validate this conclusion. [ABSTRACT FROM AUTHOR]

Colorectal cancer (CRC) is a known complication of inflammatory bowel disease (IBD). Widely accepted guidelines recommend that patients with ulcerative colitis diagnosed with CRC undergo total proctocolectomy with or without ileal pouch-anal anastomosis, and that patients with Crohn's disease and CRC undergo either total colectomy or proctocolectomy. These approaches are ideal for preventing synchronous and metachronous cancer, minimizing risk of refractory colitis requiring reoperation, and is the appropriate treatment for the vast majority of patients with IBD who are diagnosed with CRC and require surgical intervention. Segmental colectomy, however, may be considered in select patients with IBD and CRC, specifically in elderly patients with short disease duration, in patients with mild colitis identified preoperatively, in patients with high operative risk and prohibitive comorbidities, and in patients whose CRC appears to be sporadic as opposed to colitis-associated. Patients undergoing segmental resection must be closely surveilled postoperatively for dysplasia, recurrent cancer, and refractory colitis. [ABSTRACT FROM AUTHOR]

Purpose: To assess the impact of surgical approach on morbidity, mortality, and the oncological outcomes of synchronous (SC) and metachronous (MC) colorectal cancer (CRC). Methods: All patients undergoing resection for double location CRC (SC or MC) between 2006 and 2020 were included. The exclusion criteria were polyposis or SC located on the same side. Results: Sixty-seven patients (age, 64.8 years; male, 78%) with SC (n = 41; 61%) or MC (n = 26; 39%) were included. SC was treated with segmental colectomy (right and left colectomy/proctectomy; n = 19) or extensive colectomy (subtotal/total colectomy or restorative proctocolectomy with pouch; n = 22). Segmental colectomy was associated with a higher incidence of anastomotic leakage (47.4 vs. 13.6%; p = 0.04) and a higher rate of medical morbidity (47.4 vs. 16.6%; p = 0.04). The mean number of lymph nodes harvested was similar. For MC, the second cancer was treated by iterative colectomy (n = 12) or extensive colectomy (n = 14) and there was no significant difference in postoperative outcomes between the two surgical approaches. The median follow-up period was 42.4 ± 29.1 months. The 5-year overall and disease-free survival of the SC and MC groups did not differ to a statistically significant extent. Conclusions: Extensive colectomy should be preferred for SC to reduce morbidity and improve the prognosis. In contrast, iterative colectomy can be performed safely for patients with MC.

Abstract Background Previous research was yet to establish a definite operation for transverse colon cancer (TCC); surgical procedure was often dictated by the surgeon’s preference in clinical practice. The main surgical methods could be summarized in two main points: segmental colectomy (transverse colectomy) and right hemicolectomy. Method The first patient was a 78-year-old woman, who was diagnosed with right TCC. Computed tomography revealed a right TCC and a very long transverse colon; laparoscopic exploration revealed an enlarged apical lymph node surrounding the ileocolic vessels. We performed a segmental colectomy with extensive apical lymph node dissection along the superior mesenteric vessels and its main branches for her. To distinguish it from the previous radical operations for TCC, we called this operation a segmental colectomy with extensive D3 lymph node dissection. Then, this surgical intervention was performed on 8 other TCC patients. Results The total operating time was 158 min. Pathological examination confirmed 2 apical lymph node metastases; among them, one apical lymph node metastasis was in group No.203. For all 9 patients, the median operative time was 160 min (range, 140–185 min), the average number of lymph node retrieval was 30 (range, 25–39), and the average number of apical lymph node (No.203, No.213, and No.223) retrieval was 5.9 (range, 0–11). Because of the preservation of the ileocecal junction and part of the ascending colon, all patients recovered uneventfully after surgery, and long-term diarrhea, water-electrolyte imbalance, and other Clavien–Dindo grade III or greater postoperative complications did not occur. Conclusions Our procedure combined the advantages of segmental colectomy and right hemicolectomy and gave consideration to oncological and functional outcomes. It may be an optimal choice for TCC patients with a very long transverse colon and preoperative diagnosis of lymph node metastasis.

Objective: We herein propose a novel approach, laparoscopic segmental colectomy with extensive D3 lymph node dissection (ED3LND), for right-sided transverse colon cancer (TCC)., Methods: Forty-two patients with right-sided TCC were randomly assigned to two groups: Group 1 (segmental colectomy with D3LND) and Group 2 (segmental colectomy with ED3LND). Clinical characteristics, surgical and pathological outcomes, and oncological outcomes were retrospectively compared between the two groups., Results: The number of lymph nodes retrieved, apical lymph nodes retrieved, and apical lymph node metastases were significantly lower in Group 1 than in Group 2. No significant differences were observed in the operation time, length of hospital stay, estimated blood loss, lymph node metastases, postoperative lymphoceles, or other Clavien-Dindo grade ≥III postoperative complications between the two groups. The 3-year disease-free survival rate was 82.6% in Group 1 and 84.2% in Group 2, with no significant difference., Conclusions: Laparoscopic segmental colectomy with ED3LND for right-sided TCC may offer better oncological outcomes than D3LND. A large-scale prospective randomized controlled study is needed to further validate the oncological benefits of this novel procedure., Competing Interests: Declaration of conflicting interestsThe author declares no competing interests.

Abstract Background To identify whether compliance with Enhanced Recovery After Surgery (ERAS) Society recommendations is associated with length of stay (LOS) in a New Zealand hospital for patients undergoing segmental colectomy in mixed acute and elective general surgery wards. Methods Consecutive elective colorectal surgeries (n = 770) between October 2012 and February 2019 were audited. Patients with non-segmental colectomies, multi-organ surgeries, LOS > 14 days, and those who died were excluded. Logistic regression was used to determine the relationship between patient demographics, compliance with ERAS guidelines, and suboptimal LOS (> 4 days). Results Analysis included 376 patients. Age, surgery prior to 2014, surgical approach, non-colorectal surgical team, operation type, and complications were significantly associated with suboptimal LOS. Non-compliance with ERAS recommendations for laparoscopy [OR 8.9, 95% CI (4.52, 19.67)], removal of indwelling catheters (IDC) [OR 3.14, 95% CI (1.85, 5.51)], use of abdominal drains [OR 4.27, 95% CI (0.99, 18.35)], and removal of PCA [OR 8.71, 95% CI (1.78, 157.27)], were associated with suboptimal LOS (univariable analysis). Multivariable analysis showed that age, surgical team, late removal of IDC, and open approach were independent predictors of suboptimal LOS. Conclusions Non-compliance with ERAS guidelines for laparoscopic approach and early removal of IDC was higher among procedures performed by non-colorectal surgery teams, and was also associated with adverse postoperative events and suboptimal LOS. This study demonstrates the importance of the surgical team’s expertise in affecting surgical outcomes, and did not find significant independent associations between most individual ERAS guidelines and suboptimal LOS once adjusting for other factors.

Background: Combined-Endoscopic-Laparoscopic-Surgery (CELS) was developed for benign colonic polyps, endoscopically unresectable, to avoid segmental colectomy. This observational study aims to compare surgical outcomes of endoscopically unresectable colonic polyps treated laparoscopically before and since the institutional introduction of CELS. Primary endpoint was postoperative morbidity and mortality; secondary endpoints were time of hospitalization and histopathological findings. Methods: Charts of all patients with preoperative diagnosis of benign colonic tumors, treated laparoscopically at our institution from 1/2010 to 2/2020 were reviewed. Patients with polyps (1) affecting ileocecal valve, (2) occupying > 50% of the circumference, (3) ≥ 3 endoscopically unresectable polyps, (4) inflammatory bowel disease, (5) polyps within diverticular area post diverticulitis, (6) rectal polyps (7) foreseen impossibility of laparoscopy (8) preoperatively biopsy proven invasive adenocarcinoma were excluded. Group I consists of all patients potentially treatable by CELS but operated by laparoscopic colonic resection as CELS was not yet institutionally established. Group II includes all patients treated with CELS (since 11/2017). Results: One hundred-fifteen consecutive patients were reviewed. Applying exclusion criteria, twenty-three patients form group I and twenty-three group II (female 30.4%, median age 68 years). Groups distributed homogenously for age, BMI (body mass index) and polyps´ localization with most polyps (60.4%) localized in right colon; group II patients had significantly higher American Society of Anesthesiologists (ASA) score. Median operating time, hospital stay and morbidity were significantly less in group II. Postoperative morbidity occurred overall in 14 patients (30.4%), mostly Clavien-Dindo class I-II (26.1%) and significantly less in group II (p = 0.017), Clavien-Dindo III-IV distributed equally (one patient each group) without postoperative mortality. Definitive histopathology showed invasive adenocarcinoma in 8.3% without differences between groups. Two patients with invasive adenocarcinoma after CELS were advised for oncological resection. Conclusion: CELS is safe and efficient to treat complex, benign colonic polyps by a complete minimal invasive laparoscopic approach. CELS showed better surgical outcomes with less morbidity, no mortality and appropriate pathological results avoiding unnecessary laparoscopic surgery with intestinal anastomosis.

Aim: The different surgical options for patients with colonic Crohn's disease (CD) include segmental colectomy, subtotal colectomy or proctocolectomy with end ileostomy. We present a national, multicentre study, promoted by the Italian Society of Colorectal Surgery with the aim to collect benchmark data and national variations on multidisciplinary management and postoperative outcomes of patients undergoing surgery for colonic CD. Methods: All adult patients having elective surgery for colonic CD from June 2018 to May 2019 were eligible for participation in this retrospective study. The primary outcome measure was postoperative morbidity within 30 days of surgery. Results: One hundred twenty-two patients were included: 55 subtotal colectomy, 30 segmental colectomy, 25 proctectomy and 12 proctocolectomy. Eighty-six patients (70.4%) were discussed at the inflammatory bowel disease (IBD) multidisciplinary team meeting (MDT) prior to surgery. This ranged from 76.6% for segmental colectomy to 60% for subtotal colectomy, 66.6% for proctocolectomy and 48% for proctectomy. The proportion of patients counselled by a stoma nurse preoperatively was 50%. Laparoscopy was associated with reduced postoperative morbidity (p = 0.017) and shorter length of hospital stay (p < 0.001), whilst pre-operative anti-TNF was associated with Dindo-Clavien ≥ 3 complications (p = 0.023) and longer in-hospital stay (p = 0.007). The main procedure performed (segmental colectomy, subtotal colectomy, proctocolectomy or proctectomy) was not associated with postoperative morbidity (p = 0.626). Conclusions: Surgery for colonic CD has a high rate of postoperative complications. Almost a third of the patients were not preoperatively discussed at the IBD MDT, whilst the use of minimally invasive surgery for surgical treatment of colonic CD ranges from 40 to 66%.

Aim: There is no consensus on the appropriate extent of oncological resection for tumours of the transverse colon. Concerns regarding tumour factors such as pattern of lymph node spread and technical factors such as anastomotic perfusion lead to a variety of procedures being performed. Methods: A comprehensive search for published studies examining outcomes following segmental versus extended colectomy for transverse colon tumours was performed adhering to PRISMA (Preferred Reporting Items in Systematic Reviews and Meta‐analyses) guidelines. Random effects methods were used to combine data. Results: Seven comparative series examining outcomes in 3395 patients were identified. Segmental colectomy results in shorter operating times (mean difference 15.80 min, 95% CI −20.98 to −10.62, P < 0.001) and less ileus (OR 0.52, 95% CI 0.33–0.81, P = 0.004). There was no difference in length of hospital stay (mean difference 1.53 days, 95% CI −3.79 to 0.73, P = 0.18). Extended colectomy results in a lower rate of anastomotic leak (OR 0.62, 95% CI 0.40–0.97, P = 0.04). There are fewer nodes retrieved in segmental colectomy (mean difference 7.60 nodes, 95% CI −9.60 to −5.61, P < 0.001) but no difference in disease recurrence (OR 0.88, 95% CI 0.59–1.34, P = 0.56) or overall survival (OR 0.98, 95% CI 0.68–1.4, P = 0.9). Conclusions: Available data are limited due to a lack of randomized controlled trials. However, based on current evidence, segmental resection for transverse colon tumours is associated with less ileus but lower lymph node yields and higher anastomotic leak rates. Length of stay is similar. Oncological outcomes are equivalent. [ABSTRACT FROM AUTHOR]

Background and Aims The aim of this study was to report a multicentric experience of segmental colectomy [SC] in ulcerative colitis [UC] patients without active colitis, in order to assess if SC can or cannot represent an alternative to ileal pouch-anal anastomosis [IPAA]. Methods All UC patients undergoing SC were included. Postoperative complications according to ClavienDindo's classification, long term results, and risk factors for postoperative colitis and reoperation for colitis on the remnant colon, were assessed. Results: A total of 72 UC patients underwent: sigmoidectomy [ n = 28], right colectomy [ n = 24], proctectomy [ n = 11], or left colectomy [ n = 9] for colonic cancer [ n = 27], 'diverticulitis' [ n = 17], colonic stenosis [ n = 5], dysplasia or polyps [ n = 8], and miscellaneous [ n = 15]. Three patients died postoperatively and 5/69 patients [7%] developed early flare of UC within 3 months after SC. After a median followup of 40 months, 24/69 patients [35%] were reoperated after a median delay after SC of 19 months [range, 2–158 months]: 22/24 [92%] underwent total colectomy and ileorectal anastomosis [ n = 9] or total coloproctectomy [TCP] [ n = 13] and 2/24 [8%] an additional SC. Reasons for reoperation were: colitis [ n = 14; 20%], cancer [ n = 3] or dysplasia [ n = 3], colonic stenosis [ n = 1], and unknown reasons [ n = 3]. Endoscopic score of colitis before SC was Mayo 23 in 5/5 [100%] patients with early flare vs 15/42 without early flare [36%; p = 0.0101] and in 9/12 [75%] patients with reoperation for colitis vs 11/35 without reoperation [31%; p = 0.016]. Conclusions After segmental colectomy in UC patients, postoperative early colitis is rare [7%]. Segmental colectomy could possibly represent an alternative to IPAA in selected UC patients without active colitis. [ABSTRACT FROM AUTHOR]

Introduction: The historical management for patients with ulcerative colitis and displasia or adenocarcinoma associated was to perform a total proctocolectomy, what cause important morbidity and affect patient’s quality of life. Materials and Method: A retrospective review about 5 patients with a segmental colectomy due to dysplasia or adenocarcinoma is done. Results: The median age at diagnosis of ulcerative colitis and cancer was 56 and 62 years respectively. Disease time evolution was between 1 and 13 years. The patients were followed up for a median of 57 months. During the follow-up evaluation, 1 patient was found to have dysplasia. Conclusion: Segmental colectomy could be a safe option in clinically stable patients, few years of diagnosis and with and a suitable follow up. [ABSTRACT FROM AUTHOR]

Transverse colon cancer (TCC) is poorly studied, and TCC cases are often excluded from large prospective randomized trials because of their complexity and their potentially high complication rate. The best surgical approach for TCC has yet to be established. The aim of this large retrospective multicenter Italian series is to investigate the advantages and disadvantages of both hemicolectomy and transverse colectomy in order to identify the best surgical approach. This was a retrospective cohort study of patients with mid-transverse colon cancer treated with a segmental colon resection or an extended hemicolectomy (right or left) between 2006 and 2016 in 28 high-volume (more than 70 procedures/year) Italian referral centers for colorectal surgery. The study included 1529 patients, 388 of whom underwent a segmental resection while 1141 underwent an extended resection. A higher number of complications has been reported in the segmental group than in the extended group (30.1% versus 23.6%; p 0.010). In 42 cases the main complication was the anastomotic leak (4.4% versus 2.2%; p 0.020). Recovery outcomes also showed statistical differences: time to first flatus (p 0.014), time to first mobilization (p 0.040), and overall hospital stay (p < 0.001) were significantly shorter in the extended group. Even if overall survival were similar between the groups (95.1% versus 97%; p 0.384), 3-year disease-free survival worsened after segmental resection (78.1% versus 86.2%; p 0.001). According to our results, an extended right colon resection for TCC seems to be surgically safer and more oncologically valid. [ABSTRACT FROM AUTHOR]

Background: Initial surgical procedures for colorectal cancer (CRC) patients with Lynch syndrome remain controversial. This study assessed the validity of segmental colectomy (SGC) followed by endoscopic surveillance as a treatment strategy for CRC patients with Lynch syndrome. Methods: Among consecutive patients who underwent surgery for primary CRC between April 1985 and December 2014, 49 patients were observed to have germline mutations in a mismatch repair gene, and 38 patients who underwent SGC followed by periodic endoscopic surveillance at our institution were evaluated for metachronous CRC, need for secondary surgery, and the details of endoscopic surveillance. Results: Of the 38 patients who underwent SGC followed by periodic endoscopic surveillance at our institution, 6 (15.8%) patients showed metachronous CRC, 3 (7.9%) patients underwent endoscopic resection, and the other 3 patients (7.9%) underwent secondary surgery. The dispersion of the endoscopic surveillance interval was significantly greater in patients with metachronous CRC (364 ± 332.9 days) than in those without metachronous CRC (370 ± 129.7 days; p < 0.001). Conclusions: SGC followed by annual endoscopic surveillance was feasible as a treatment strategy for CRC patients with Lynch syndrome, because the incidence of metachronous CRC and the need for secondary surgery were low. Annual and periodic endoscopic surveillance might be essential for early detection of metachronous CRC and prevention of secondary surgery because of metachronous CRC in CRC patients with Lynch syndrome after SGC.

Aim Lynch syndrome ( LS) accounts for 2-4% of all colorectal cancer ( CRC) cases, and is associated with an increased risk of developing metachronous colorectal cancer ( mCRC). The role of extended colectomy in LS CRC is controversial. There are limited studies comparing the risk of mCRC following segmental colectomy and extended colectomy. The objective of this systematic review is to evaluate the risk of developing mCRC following segmental and extended colectomy for LS CRC and endoscopic compliance. Method A systematic review of major databases was performed using predefined terms. All original articles published in English comparing the risk of mCRC in LS patients after segmental and extended colectomy from 1950 to January 2016 were included. Results The search retrieved 324 studies. Six studies involving 871 patients met the inclusion criteria. Of these, 705 (80.9%) underwent segmental colectomy and 166 (19.1%) extended colectomy. Average follow-up was 91.2 months. The mCRC rate was 22.8% and 6% in the segmental and extended colectomy groups, respectively. The segmental group were over four times more likely to develop mCRC ( OR 4.02, 95% CI: 2.01-8.04, P < 0.0001). mCRC occurred in patients after segmental colectomy despite 1-2-yearly postoperative endoscopic surveillance. Conclusion This result suggests that extended colectomy reduces the risk of mCRC by over four-fold compared with segmental colectomy. mCRC occurred in the segmental group despite postoperative endoscopic surveillance. This needs to be borne in mind when deciding on the appropriate surgical management of LS patients with CRC. We recommend that extended colectomy should be considered for patients with confirmed LS CRC. [ABSTRACT FROM AUTHOR]

Aim The optimal surgical approach to the management of colorectal cancer in the setting of hereditary nonpolyposis colorectal cancer ( HNPCC) is contentious. While some advocate total colectomy, others perform segmental resection followed by regular endoscopic surveillance. This systematic review evaluates the evidence for segmental colectomy ( SC) and total (extended) colectomy ( TC) in the management of HNPCC. Method Two major databases ( Pub Med and Cochrane) were searched using predefined terms. All original articles, published in English, comparing the oncological outcomes of SC and TC in HNPCC patients from January 1950 to July 2013 were included. Results Eighty-four studies were identified. After applying exclusion criteria, six studies involving 948 patients were included (mean age 47.4 years, 51.8% male). SC was more commonly performed than TC ( n = 780; 82.3%). Mean follow-up was 106.5 months. Metachronous high-risk adenomas were detected more often after SC, although the difference was not statistically significant (23.4% vs 9.6%; OR 2.258, P = 0.057). Metachronous cancers occurred more frequently after SC than after TC (23.5% vs 6.8%; OR 3.679, P < 0.005). However, there was no difference in overall survival (90.7% vs 89.8% for SC and TC, respectively; P = 0.085). Only one study reported operative mortality (0% in each group), there was no report of operative morbidity or functional outcome. Conclusion The optimal surgical approach in the management of HNPCC remains unclear. More adenomas and cancers occur after SC than after TC but there certainly is no evidence to suggest that more radical surgery leads to improved survival. [ABSTRACT FROM AUTHOR]

The surgical management of the Lynch syndrome patient with colorectal cancer needs to be individualized. Because of the increased incidence of synchronous and metachronous colorectal neoplasms, most favor an extended resection at the time of diagnosis of colorectal cancer. Age of diagnosis, stage of the tumor, co-morbidities, surgical expertise, surgical morbidity, and patient wishes should be taken into account when considering a surgical procedure. There are no prospective randomized trials or retrospective trials suggesting that patients undergoing an extended procedure have a survival advantage compared to those undergoing segmental resection. In retrospective studies it has been demonstrated that patients undergoing extended procedures will develop less metachronous colorectal neoplasms and will undergo less subsequent surgical procedures related to colorectal cancer. In females abdominal hysterectomy and bilateral salpingoophorectomy should be considered at the time of surgery for colorectal cancer. [ABSTRACT FROM AUTHOR]

Most patients with colon cancer are surgically treated, with postoperative association of chemotherapy and possibly immunotherapy in advanced cases. Surgical treatment is chosen depending on the evolution stage, tumor topography and the existence of complications, colonic surgery being dictated by colonic vascularization. The radical character of the surgical intervention can be assured only in the early stages of the tumor. Colostomy is rarely necessary in patients with colon cancer. In the period of the last 5 years (2007-2011), 307 patients with colon cancer were operated in "Colentina" Surgical Clinic, radical intervention being possible only in 219 cases. 48 cases were emergency interventions for occlusion or perforation with peritonitis. Every time the mechanical preparation of the bowel was not possible, the intraoperative washout technique was used. Postopera~ve complications were met in 27 cases, being represented by bleeding (3 cases), peritoneal abscess (5 cases), anastomotic fistula (7 cases), abdominal wound infection (12 cases). In 5 cases the operation was done laparoscopically. Preoperative mortality was of 13 cases. Postoperative chemotherapy was done in the great majority of cases. [ABSTRACT FROM AUTHOR]

Crohn’s disease in childhood is changing. The incidence is increasing, colonic disease is becoming more prevalent in younger children, and colon reconstruction is more acceptable. Genetic phenotypes are influencing decisions for surgery, and targeted immunotherapy has renewed hope for more durable remissions following less extensive resections. The tasks facing the surgeon evaluating a child with Crohn’s colitis include confirming the specific diagnostic subtype and selecting the correct procedure. This chapter will review the unique aspects of pediatric Crohn’s colitis and the increased complexity of surgical choice for this most challenging presentation. Recent success with less extensive surgery offers renewed hope for children with intractable colonic disease. [Copyright &y& Elsevier]
