RESUMEN
BACKGOUND: Effective, standardized treatments for complex anal fistula (CAF) still represent a clinical challenge. Emerging procedures attempted to achieve the healing rates of fistulotomy whilst preserving sphincter function. Acellular dermal matrix (ADM) used as a plug inserted through the fistulous tract is among newer treatment options. Varying success rates have been reported, most with short-term follow-up. The aim of this study was to report the long-term results of ADM-plug for CAF. METHODS: Retrospective analysis of a prospective database of patients treated with CAF. All consecutive patients presenting at two tertiary centers (Vall d'Hebron University Hospital and Bellvitge University Hospital, Barcelona, Spain) between November 2015 and March 2019 with a single, cryptoglandular CAF were evaluated for treatment with an ADM-plug were included. The primary endpoint was absence of discharge at clinical examination at 12 month follow-up. RESULTS: Twenty-two patients were included [7 women and 15 men, median age 56 (33-74) years]. Most patients had high transsphincteric fistulas (63.6%). The median follow-up was 42 (21-53) months. The 12 month success rate was 68.2%, with an overall healing rate of 59.1%. 77.8% of recurrences occurred within 12 months from surgery. One plug extrusion was observed. No major complications or mortality occurred during the follow-up. Patients did not report any worsening of fecal continence. CONCLUSIONS: This pilot study showed that more than half of patients with CAF could benefit from ADM-plug placement, preserving continence. A minimum follow-up of 12 months is recommended, because most recurrences occur during the first year.

BACKGROUND: Defunctioning ileostomy creation and closure are both associated with morbidity. There is little data available about complications after ileostomy closure. The aim of this study was to evaluate morbidity related to loop ileostomy closure (LIC) and to determine if patients with postoperative complications in primary surgery suffer from more postoperative complications during stoma closure. METHODS: This was a retrospective study on prospectively registered consecutive patients undergoing elective LIC in a single centre in Spain between April 2010 and December 2017. Baseline characteristics, postoperative complications after primary surgery and after stoma closure were recorded. Primary surgery included any colorectal resection, elective or urgent associated with a diverting loop ileostomy either as a protective stoma or rescue procedure. A logistic regression model was used to assess the effects of baseline variables and postoperative complications after primary surgery on the existence of postoperative complications related to LIC. RESULTS: Four hundred and twenty-eight patients (288 men, median age 64.5 years [IQR 55.1-72.3 years]) were included in the study, and 37.4%, developed complications after LIC. The most common was paralytic ileus. Only chronic kidney disease (OR 2.31; 95% CI 1.03-5.33, p = 0.043), existence of postoperative complications after primary surgery (OR 2.25; 95% CI 1.41-3.66, p = < 0.001) and ileostomy closure later than 10 months after primary surgery (OR 1.52; 95% CI 1.00-2.33, p = 0.049) were statistically significant in the multivariate analysis. CONCLUSIONS: Patients with chronic kidney disease, those who had any complication after primary surgery and those who had LIC > 10 months after primary surgery have a significantly higher risk of developing postoperative complications.

AIM: Anastomotic leakage is a major complication after right hemicolectomy leading to increased morbidity, mortality, length of stay and hospital costs. Previous studies have shown that the type of anastomosis (handsewn or stapled) is a major risk factor for anastomotic leakage. The purpose of this study was to evaluate the clinical impact of anastomotic leakage depending on the type of anastomotic technique (handsewn vs stapled). METHOD: This was an observational, retrospective, cross-sectional study. Data were collected at two major hospitals in Spain from January 2010 to December 2016. Patients had elective right colectomy for cancer with handsewn or stapled ileocolic anastomosis. The main outcome was the grading of postoperative treatments needed to manage anastomotic leakage according to two major classification systems. The other outcomes were demographics, time of hospitalization and death rate. RESULTS: Patients (n = 961) underwent elective surgery for neoplasia of the right colon. Anastomotic leakage was diagnosed in 116 patients (12.07%). Patients with handsewn anastomosis had more Type IIIA surgical complications and received milder treatments than patients with stapled anastomosis (SA) who had more Type IIIB complications and more re-laparotomies (P = 0.004). The clinical impact of anastomotic leakage was significantly more severe (Grade C) in patients with SA than in patients with a handsewn anastomosis (P = 0.007). No differences were found for hospital stay of patients with anastomotic leakage depending on the type of anastomosis (P = 0.275). Death due to anastomotic leakage was similar in both groups. CONCLUSIONS: The clinical impact of anastomotic leakage in patients with handsewn anastomosis is lower than in patients with SA.

AIM: A prophylactic three-dimensional (3D) funnel mesh using the keyhole technique (intraperitoneal onlay mesh position) in abdominoperineal excision (APR) may significantly decrease the parastomal hernia (PSH) index without increasing morbidity. The aim of this retrospective observational study was to analyse the incidence of PSH and postoperative complications in patients who underwent permanent colostomy with the use of a prophylactic 3D preformed mesh compared with patients without a mesh. METHOD: Patients who underwent an end-colostomy after APR for primary or recurrent rectal cancer in a colorectal surgery unit were divided into two groups: group 1 without a prophylactic mesh and group 2 with a prophylactic synthetic mesh. The main end-point was to analyse the incidence of PSH after a median follow-up of 2.8 years. RESULTS: One hundred and ten patients (64 in group 1 and 46 in group 2, without significant clinical differences) underwent a permanent colostomy after APR. In group 1 70.3% developed a PSH, compared with 13% in group 2 (P < 0.001). Age (especially for patients ≥ 75 years) represented a significant risk factor for PSH. There were no differences in postoperative complications between the groups. CONCLUSION: A prophylactic parastomal 3D mesh using the keyhole technique may reduce the incidence of PSH after permanent colostomy without an increase in postoperative complications.

BACKGROUND: Distal Doppler-guided transanal hemorrhoidal dearterialization with mucopexy (Doppler-guided THD) seems to be associated with better short-term outcomes than conventional hemorrhoidectomy, but there are little data about long-term recurrence. The aim of this study was to compare Doppler-guided THD for grade III-IV hemorrhoids with conventional hemorrhoidectomy with regard to long-term postoperative morbidity and recurrence. METHODS: This was a single-center longitudinal and comparative study of a cohort of patients who underwent either distal Doppler-guided THD with low ligation of the hemorrhoidal artery and mucopexy or conventional excisional hemorrhoidectomy (Milligan and Morgan or Ferguson) for grade III and IV hemorrhoids. Short- and long-term postoperative morbidity was recorded. Severity of hemorrhoid symptoms (bleeding, prolapse, manual reduction, discomfort or pain and impact on quality of life) and fecal continence status (Vaizey score) were evaluated before surgery and at minimum of 1 year after surgery. RESULTS: Eighty-three patients were included in the study. Forty-nine patients (59%) underwent Doppler-guided THD, and 34 (41%) patients underwent conventional hemorrhoidectomy. The 30-day postoperative surgical morbidity was 26.5% in the Doppler-guided THD group and 8.82% in the conventional hemorrhoidectomy group (p = 0.085). No significant differences between the groups were observed in terms of persistence of bleeding, prolapse, need for manual reduction in prolapse and pain. One (2%) patient in the THD group and 2 (5.4%) patients in the conventional hemorrhoidectomy group needed further surgical procedures. Minor fecal incontinence occurred only after conventional hemorrhoidectomy in 2 (5.4%) patients. CONCLUSIONS: Our results showed that Doppler-guided THD is not inferior to conventional excisional hemorrhoidectomy for advanced hemorrhoidal disease in terms of postoperative complications and long-term recurrence of symptoms.

Changes in the multidisciplinary treatment of rectal cancer have been recently proposed. We performed a comprehensive review of the current data on neoadjuvant and adjuvant treatment of rectal cancer, focussing on chemoradiotherapy treatment and timing of surgery. Six components were proposed as the framework for the treatment of rectal cancer: neoadjuvant therapy and changing patterns in patient selection, long- or short-course radiotherapy, adverse effects of radiotherapy, timing of surgery, non-operative management of rectal cancer and postoperative adjuvant therapy. Lack of a consistent difference in terms of local recurrence has been observed between short-course radiotherapy and long-course chemoradiotherapy. Indications for preoperative radiotherapy have been reconsidered in the last years. An interval of 10-11 weeks seemed to be the optimal timing, with no impact on patient safety. Since assessment criteria of clinical complete response are not well defined, and the basis for non-operative management of rectal cancer is still not clear, further investigations are required. There is controversy about standard treatments for patients with locally advanced rectal cancer that are being analyzed by ongoing studies. Tailored treatments could avoid over-treatment for a large number of patients without any impairment of the oncologic results.

AIM: The aim of this prospective double-blind randomized clinical trial was to determine whether preperitoneal continuous wound infusion (CWI) of the local anaesthetic ropivacaine after either laparotomy or video-assisted laparoscopy for colorectal surgery would reduce patient consumption of morphine. METHOD: Patients scheduled for colorectal surgery randomly received a 48-h preperitoneal CWI of either 0.38% ropivacaine or 0.9% saline at rates of 5 ml/h after laparotomy or 2 ml/h after laparoscopy. The primary end-point was total morphine consumption in surgery and afterwards through a patient-controlled analgesia device. Results in the laparotomy and laparoscopy subgroups were also compared. RESULTS: Sixty-seven patients were included, 33 in the ropivacaine CWI group and 34 in the saline group. Median [interquartile range (IQR)] morphine consumption was lower in the ropivacaine group [23.5 mg (11.25-42.75)] than in the saline group [52 mg (24.5-64)] (P = 0.010). Morphine consumption was also lower in the laparotomy subgroup receiving ropivacaine [21.5 (15.6-34.7)] than in the saline group [52.5 (22.5-65) ml] (P = 0.041). Consumption was statistically similar in laparoscopy patients on ropivacaine or saline. No side effects were observed. Sixteen patients had a surgical wound infection (23.9%); 11 (16.4%) presented wound infection and five (7.5%) organ space infection. Forty-six catheter cultures were obtained; 10 (21.7%) were positive, assessed to be due to contamination. CONCLUSION: Preperitoneal CWI of ropivacaine is a good, safe addition to a multimodal analgesia regimen for colorectal surgery. CWI can reduce morphine consumption without increasing adverse effects.

AIM: Immunosuppression is believed to worsen outcomes for patients who require surgery for perforated diverticulitis. The aim of this study was to compare surgical outcomes between immunocompromised and immunocompetent patients undergoing surgery for complicated diverticulitis. METHOD: All patients who underwent emergency surgery for complicated diverticulitis between 2004 and 2012 in a single unit were studied. Patients were classified as immunosuppressed (group I) or immunocompetent (group II). Operation type and postoperative morbidity and mortality were compared between groups. The impact of operating surgeons' specialization and the Peritonitis Severity Score (PSS) were also evaluated to determine their impact on the restoration of gastrointestinal (GI) continuity. RESULTS: One-hundred and sixteen patients (mean age: 63.7 years), 41.4% women, were included. Fifty-three (45.7%) patients were immunosuppressed (group I): 42 underwent Hartmann's procedure (HP) (79.2%), nine (17.0%) underwent resection and primary anastomosis (RPA) with ileostomy (IL) and two (3.8%) underwent RPA without IL. In group II, 15 HP (23.8%), nine RPA with IL (14.3%) and 39 RPA without IL (61.9%) were performed. Postoperative morbidity and mortality were 79.2% and 26.4%, respectively, in group I and 63.5% and 6.3%, respectively, in group II. The overall mean PSS was 9.5, with a mean PSS of 11.1 in group I and of 8.1 in group II. The decision to perform a primary anastomosis differed significantly between colorectal surgeons and general surgeons in the patients with a PSS of 9-10-11. CONCLUSION: In immunocompromised patients, RPA with IL can be a safe surgical option, whereas HP should be reserved for patients with a PSS of > 11. Colorectal surgical specialization is associated with higher rates of restoration of GI continuity in patients with perforated diverticulitis, especially in patients with an intermediate PSS score. Evaluation of each patient's PSS facilitates decision making in surgery for perforated diverticulitis.

BACKGROUND: Abdominal perineal excision (APE) was originally described with levator ani removal for rectal cancer. An even wider, more aggressive extralevator resection for APE has been proposed. Although some surgeons are performing a very wide 'extralevator APE (ELAPE)', there are few data to recommend it routinely. This multicentre study aimed to compare outcomes of APE and ELAPE. METHODS: A multicentre propensity case-matched analysis comparing two surgical approaches (APE and ELAPE) was performed. All patients who underwent abdominoperineal resection of a rectal tumour were considered for the analysis. Tumour height was defined by magnetic resonance imaging measurement and patients with stage II-III tumours had neoadjuvant radiochemotherapy. Involvement of the circumferential resection margin (CRM) and intraoperative tumour perforation were the main outcome measures. A logistic regression model was used to study the relationship between the surgical approaches and outcomes. RESULTS: From January 2008 to March 2013 a total of 1909 consecutive patients underwent APE or ELAPE, of whom 914 matched patients (457 in each group) formed the cohort for analysis. Intraoperative tumour perforation occurred in 7.9 and 7.7 per cent of patients during APE and ELAPE respectively (P = 0.902), and there was CRM involvement in 13.1 and 13.6 per cent (P = 0.846). There were no differences between APE and ELAPE in terms of postoperative complication rates (52.3 versus 48.1 per cent; P = 0.209), need for reoperation (7.7 versus 7.0 per cent; P = 0.703), perineal wound problems (26.0 versus 21.9 per cent; P = 0.141), mortality rate (2.0 versus 2.0 per cent; P = 1.000) and local recurrence rate at 2 years (2.7 versus 5.6 per cent; P = 0.664). CONCLUSION: ELAPE does not improve rates of CRM involvement, intraoperative tumour perforation, local recurrence or mortality.

AIM: Ileocolic anastomosis is performed using a stapled or manual technique, but with either there is a risk of bleeding from the suture line. The aim of this study was to analyse, retrospectively, bleeding after different anastomotic techniques. METHOD: Patients having elective right colectomy were divided, according to the type of ileocolic anastomosis, into Group 1 (circular, double-stapled, end-to-side), Group 2 (linear-stapled, side-to-side) and Group 3 (handsewn, side-to-side). Postoperative lower gastrointestinal bleeding (LGIB) was studied in the three groups. Uni- and multivariate analysis was performed to study risk factors for LGIB and the need for postoperative allogeneic blood transfusion. RESULTS: Three-hundred and fifty patients were included: 174 in Group 1, 59 in Group 2 and 117 in Group 3. The postoperative LGIB rate was 4.9% and occurred exclusively in Group 1. Five patients had severe anastomotic bleeding. Postoperative blood transfusion was indicated in Groups 1, 2 and 3 in 19.0%, 5.1% and 13.7% of patients. In the five patients with severe bleeding, four attempts of colonoscopic arrest were made, achieving bleeding control in one. Angiographic embolization was successful in one patient. There were no procedure-specific complications. CONCLUSION: End-to-side, circular, double-stapling ileocolic anastomosis seems to be related to an increased incidence of anastomotic bleeding and of postoperative blood transfusion compared with patients having other techniques of ileocolic anastomosis.

AIM: Adjuvant 5-fluorouracil based chemotherapy has demonstrated benefit in Stage III colon cancer but still remains controversial in Stage II. The aim of this study was to analyse the prognostic impact of clinicopathological factors that may help guide treatment decisions in Stage II colon cancer. METHOD: Between 1996 and 2006 data from patients diagnosed with colorectal cancer at Hospital Universitari Bellvitge and its referral comprehensive cancer centre Institut Català d'Oncologia/L'Hospitalet were prospectively included in a database. We identified 432 patients with Stage II colon cancer operated on at Hospital Universitari Bellvitge. The 5-year relapse-free survival (RFS) and colon-cancer-specific survival (CCSS) were determined. RESULTS: The 5-year RFS and CCSS were 83% and 88%, respectively. Lymphovascular or perineural invasion was associated with RFS [hazard ratio (HR) 1.84; 95% CI 1.01-3.35]. Gender (women, HR 0.48; 95% CI 0.23-1) and lymphovascular or perineural invasion (HR 3.51; 95% CI 1.86-6.64) together with pT4 (HR 2.79; 95% CI 1.44-5.41) influenced CCSS. In multivariate analysis pT4 and lymphovascular or perineural invasion remained significantly associated with CCSS. We performed a risk index with these factors with prognostic impact. Patients with pT4 tumours and lymphovascular or perineural invasion had a 5-year CCSS of 61%vs the 93% (HR 5.87; 95 CI 2.46-13.97) of those without any of these factors. CONCLUSION: pT4 and lymphatic, venous or perineural invasion are confirmed as significant prognostic factors in Stage II colon cancer and should be taken into account in the clinical validation process of new molecular prognostic factors.

AIM: There has been controversy about the presentation and treatment of acute colonic diverticulitis (AD) in young patients. The aim of this observational study was to evaluate the virulence and natural history of AD in three different age groups of patients. METHOD: The study was performed on 686 patients with the diagnosis of a first episode of AD admitted between January 1998 and December 2008. Patients were classified into three groups: age 45 years or younger (group 1), 45-70 years of age (group 2) and 70 years or more (group 3). The variables studied were gender, American Society of Anesthesiologists status, associated comorbidity, type of treatment, length of hospital stay and recurrence of AD. RESULTS: Group 1 included 99 (14.4%) patients, group 2 339 (49.4%) and group 3 248 (36.2%). Of these, 144 patients needed emergency operation at the first admission, 25 underwent elective surgery after the first episode of AD and 10 died after medical treatment; 507 patients were followed for recurrence. In all, 104 (20.5%) patients had a recurrence of AD that required hospitalization. Fifty (9.9%) presented with one episode of severe recurrence, without any difference between the groups (P = 0.533). There were no differences in the analysis of cumulative recurrence (Kaplan-Maier) between the three groups. CONCLUSION: AD does not present a more aggressive clinical course in younger patients and it can be safely managed using the same strategy as in middle aged and older patients.

AIM: This paper addresses the current status of the treatment of acute colonic diverticulitis by an evidence-based review. METHOD: A systematic search in PUBMED, MEDLINE, EMBASE and Google scholar on colonic diverticulitis was performed. Diagnostic tools, randomized controlled trials, non-randomized comparative studies, observational epidemiological studies, national and international guidelines, reviews of observational studies on elective and emergency surgical treatment of diverticulitis, and studies of prognostic significance were reviewed. Criteria for eligibility of the studies were diagnosis and classification, medical treatment, inpatients and outpatients, diverticulitis in young patients, immunosuppression, recurrence, elective resection, emergency surgery, and predictive factors. RESULTS: Some 92 publications were selected for comprehensive review. The review highlighted that computed tomography is the most effective test in the diagnosis and staging of acute diverticulitis; outpatient treatment can be performed for uncomplicated diverticulitis in patients without associated comorbidities; conservative treatment is aimed at those patients with uncomplicated acute diverticulitis; elective surgery must be done on an individual basis; laparoscopic approach for elective treatment of diverticulitis is appropriate but may be technically complex; in perforated diverticulitis, resection with primary anastomosis is a safe procedure that requires experience and should take into account strict exclusion criteria. CONCLUSION: The heterogeneity of patients with colonic diverticular disease means that both elective and urgent treatment should be tailored on an individual basis.

AIM: Surgical site infection (SSI) is the most common cause of morbidity after colorectal surgery. The aim of this study was to analyze risk factors for SSI in patients who had undergone surgery for rectal cancer. METHOD: A multicentre observational study was carried out on 2131 patients operated on for rectal cancer between May 2006 and May 2009. Twenty-nine centres were involved. SSI included wound infection and organ space infection within 30 days after the operation. Univariate and multivariate analyses were carried out to study possible risk factors for SSI. RESULTS: Wound infection and organ space infection were diagnosed in 8.9% and 10%, respectively, of patients. The anastomotic leakage rate was 8%. Multivariate analysis showed that wound infection was related to tumour stage, a converted laparoscopic procedure and open surgery. Organ space infection was related to Stage IV tumour, a tumour < 11 cm from the anal verge, low anterior resection and Hartmann's procedure. CONCLUSION: Rectal surgery for malignant disease is associated with a considerable rate of SSI. Wound infection and organ space infection are related to different factors and therefore should be evaluated separately.

AIM: To study any possible differences in morbidity, mortality and overall survival rate after curative surgery for obstructive colon cancer according to tumour location. METHOD: From January 1994 to December 2006, patients with colonic cancer presenting as obstruction were analysed. The two groups were defined as proximal and distal according to the tumour location with respect to the splenic flexure. In relation to the surgeon specialization, patients were operated on by a colorectal surgeon and by a general surgeon. Postoperative morbidity and mortality and cancer-related survival at 3 years were analysed. RESULTS: Of the 377 patients included in the study, there were 173 patients (45.9%) in the proximal group and 204 patients (54.1%) in the distal group. The global morbidity was 54.9% without differences in postoperative morbidity except for anastomotic leakage, which was higher in the proximal group (P < 0.014). No differences in postoperative mortality were observed. After patients were stratified by the tumour node metastasis system, the differences between the groups, with respect to 3-year overall survival, cancer-related survival and probability of being free from recurrence, did not reach statistical significance. The overall survival after radical surgery for colonic obstruction was 57.6%. CONCLUSION: Mortality and morbidity after emergency surgery for obstructing colon cancer are high. Specialization in colorectal surgery influences postoperative results in terms of lower anastomotic dehiscence rate after emergency proximal colon resection. After radical surgery, tumour location does not appear to influence the prognosis of obstructive colon cancer.
