Appendico-vesicocolonic fistula: A case report and review of literature. World J Clin Cases 2022; 10:3241-3250. [PMID: 35647117 PMCID: PMC9082718 DOI: 10.12998/wjcc.v10.i10.3241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Revised: 12/30/2021] [Accepted: 02/23/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Appendico-vesicocolonic fistulas and appendiceal-colonic fistulas are two kinds of intestinal and bladder diseases that are rarely seen in the clinic. To our knowledge, no more than 4 cases of appendico-vesicocolonic fistulas have been publicly reported throughout the world, and no more than 100 cases of appendiceal-colonic fistulas have been reported. Although the overall incidence is low, an early diagnosis is difficult due to their atypical initial symptoms, but these diseases still require our attention.
CASE SUMMARY Here, we report a case of a 77-year-old male patient diagnosed with an appendico-vesicocolonic fistula combined with an appendiceal-colonic fistula. The main manifestations were diarrhea and urine that contained fecal material. The diagnosis was confirmed by multiple laboratory and imaging examinations. A routine urinalysis showed red blood cells and white blood cells. Abdominal and pelvic computed tomography scans showed close adhesions between the bowels and the bladder, and fistulas could be seen. Colonoscopy and cystoscopy and some other imaging examinations clearly showed fistulas. The preoperative diagnoses were a colovesical fistula and an appendiceal-colonic fistula. The fistulas were repaired by laparoscopic surgical treatment. The diseased bowel and part of the bladder wall were removed, followed by a protective ileostomy. The postoperative diagnosis was an appendico-vesicocolonic fistula combined with an appendiceal-colonic fistula, and the pathology suggested inflammatory changes. The patient recovered well after surgery, and all his symptoms resolved.
CONCLUSION The final diagnosis in this case was a double fistula consisting of an appendico-vesicocolonic fistula combined with an appendiceal-colonic fistula.

Endoscopic management of colovesical and colovaginal fistulas with over-the-scope clips: A single-institution case series. Colorectal Dis 2022; 24:314-321. [PMID: 34762356 DOI: 10.1111/codi.15987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 10/20/2021] [Accepted: 11/01/2021] [Indexed: 12/09/2022]
Abstract
AIM Conventional surgical management of colovesical and colovaginal fistulas can be morbid and is contraindicated in many patients. Our aim in this work is to evaluate our experience in the management of colovesical and colovaginal fistulas with endoscopic over-the-scope (OTS) clips. METHOD A retrospective review of all patients who underwent attempted endoscopic OTS clip management of colovesical and colovaginal fistulas between 2013 and 2020 was performed. Preoperative risk factors, operative details and postoperative outcomes are reported. RESULTS Ten patients were identified. Fistula types were: colovesical (five), rectovesical (two), colovaginal (two) and rectovaginal (one). The aetiology of the fistula was diverticular disease in seven (70%) cases and surgical complication of pelvic surgery in three (30%). The mean defect age was 157 ± 98 days, the mean defect diameter was 4.5 mm (range 2-10 mm) and the mean fistula length was 15 mm (range 2-25 mm). In nine (90%) cases, fistula identification and cannulation were performed through the nonenteric lumen of the fistula. Initial management with an OTS clip was technically successful in eight (80%) patients. Of the eight patients who underwent OTS clip placement, long-term success (mean follow-up 218 days, range 25-673 days) was achieved after initial intervention in four (50%) patients. One patient underwent serial OTS clip procedures and achieved long-term success after four interventions; three patients have not undergone a repeat procedure after initial failure. CONCLUSION Endoscopic management of colovesical and colovaginal fistulas with OTS clips offers a promising therapeutic option for patients with contraindications to conventional surgical management. Immediate technical success and long-term success rates are similar to other gastrointestinal tract applications of OTS clips.

Colovesical Fistulae: The Varying Aetiologies. Cureus 2021; 13:e20025. [PMID: 34900497 PMCID: PMC8649672 DOI: 10.7759/cureus.20025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/29/2021] [Indexed: 11/05/2022] Open
Abstract
The most common presenting symptoms of colovesical fistulae (CVF) are pneumaturia and fecaluria. The most important aspect remains not only to investigate the aetiology, and the degree of both severity and complexity, but also the subsequent influence of this on overall management. In a younger population, management usually consists of curative surgery. However, this may not be possible in older patients where surgical candidacy is a genuine concern and a clinical challenge arises relating to pursuing a conservative strategy. We attempted to briefly outline how two patients were managed with a similar non-surgical approach due to frailty. These cases attempt to highlight the importance of multi-disciplinary specialty input, with a view to optimising patient care.

Indications and outcomes of enterovesical and colovesical fistulas: systematic review of the literature and meta-analysis of prevalence. BMC Surg 2021; 21:265. [PMID: 34044862 PMCID: PMC8157688 DOI: 10.1186/s12893-021-01272-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Accepted: 05/21/2021] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND Entero-colovesical fistula is a rare complication of various benign and malignant diseases. The diagnosis is prominently based on clinical symptoms; imaging studies are necessary not only to confirm the presence of the fistula, but more importantly to demonstrate the extent and the nature of the fistula. There is still a lack of consensus regarding the if, when and how to repair the fistula. The aim of the study is to review the different surgical treatment options, focus on surgical indications, and explore cumulative recurrence, morbidity, and mortality rates of entero-vesical and colo-vesical fistula patients. METHODS A systematic review of the literature was conducted according to PRISMA guidelines. Random effects meta-analyses of proportions were developed to assess primary and secondary endpoints. I2 statistic and Cochran's Q test were computed to assess inter-studies' heterogeneity. RESULTS Twenty-two studies were included in the analysis with a total of 861 patients. Meta-analyses of proportions pointed out 5, 22.2, and 4.9% rates for recurrence, complications, and mortality respectively. A single-stage procedure was performed in 75.5% of the cases, whereas a multi-stage operation in 15.5% of patients. Palliative surgery was performed in 6.2% of the cases. In 2.3% of the cases, the surgical procedure was not specified. Simple and advanced repair of the bladder was performed in 84.3% and 15.6% of the cases respectively. CONCLUSIONS Although burdened by a non-negligible rate of complications, surgical repair of entero-colovesical fistula leads to excellent results in terms of primary healing. Our review offers opportunities for significant further research in this field. Level of Evidence Level III according to ELIS (SR/MA with up to two negative criteria).

Abstract
Background Diabetes mellitus has been commonly associated with poor surgical outcomes. The aim of this meta-analysis was to assess the impact of diabetes on postoperative complications following colorectal surgery. Methods Medline, Embase and China National Knowledge Infrastructure electronic databases were reviewed from inception until May 9th 2020. Meta-analysis of proportions and comparative meta-analysis were conducted. Studies that involved patients with diabetes mellitus having colorectal surgery, with the inclusion of patients without a history of diabetes as a control, were selected. The outcomes measured were postoperative complications. Results Fifty-five studies with a total of 666,886 patients comprising 93,173 patients with diabetes and 573,713 patients without diabetes were included. Anastomotic leak (OR 2.407; 95% CI 1.837–3.155; p < 0.001), surgical site infections (OR 1.979; 95% CI 1.636–2.394; p < 0.001), urinary complications (OR 1.687; 95% CI 1.210–2.353; p = 0.002), and hospital readmissions (OR 1.406; 95% CI 1.349–1.466; p < 0.001) were found to be significantly higher amongst patients with diabetes following colorectal surgery. The incidence of septicemia, intra-abdominal infections, mechanical failure of wound healing comprising wound dehiscence and disruption, pulmonary complications, reoperation, and 30-day mortality were not significantly increased. Conclusions This meta-analysis and systematic review found a higher incidence of postoperative complications including anastomotic leaks and a higher re-admission rate. Risk profiling for diabetes prior to surgery and perioperative optimization for patients with diabetes is critical to improve surgical outcomes.

The colovescical fistula in diverticular disease: Laparoscopic approach in two different cases. Int J Surg Case Rep 2020; 77S:S112-S115. [PMID: 32972892 PMCID: PMC7876919 DOI: 10.1016/j.ijscr.2020.09.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 09/06/2020] [Accepted: 09/06/2020] [Indexed: 11/19/2022] Open
Abstract
The colovescical fistula is one of the complications of diverticular disease. It can cause typical symptoms like pneumaturia and fecaluria affecting the quality of life and sometimes leading to death, usually secondary to sepsis. We studied two patients with clinical, radiological and endoscopic diagnosis of colovescical fistula as a consequence of diverticular disease. We performed a totally laparoscopic treatment with colonic resection and closure of the fistula with intracorporeal sutures. The presence of a colovescical fistula significantly increases the difficult of the laparoscopic colonic resection.
Introduction The colovescical fistula is one of the complications of diverticular disease. It can cause significant symptoms like pneumaturia and fecaluria affecting the quality of life and sometimes leading to death, usually secondary to sepsis. We describe two cases of colovescical fistula treated by laparoscopic approach in patients with diagnosis of complicated acute diverticulitis. Case report We studied two patients with clinical, radiological and endoscopic diagnosis of colovescical fistula as a consequence of diverticular disease. We performed a totally laparoscopic treatment with colonic resection and colo-proctoanastomosis after the closure of the fistula with intracorporeal sutures. Discussion Colovescical fistula should be suspected in patients who present fever with persistent dysuria, pneumaturia or fecaluria. The diagnosis is confirmed by a CT abdominal scan, a colonoscopy in order to rule out a colon cancer and a cystoscopy to assess the grade of bladder involvement. Conclusion Although colovescical fistulas caused by diverticular disease were once considered a contraindication to laparoscopic resection, nowadays they are increasingly treated by experienced surgeons using laparoscopic techniques. Compared with laparoscopic surgery for uncomplicated diverticulitis the mini-invasive treatment of colovescical fistulas requires a longer operative time and advanced surgical skills.

Abstract
AIM The goal of this European Society of Coloproctology (ESCP) guideline project is to give an overview of the existing evidence on the management of diverticular disease, primarily as a guidance to surgeons. METHODS The guideline was developed during several working phases including three voting rounds and one consensus meeting. The two project leads (JKS and EA) appointed by the ESCP guideline committee together with one member of the guideline committee (WB) agreed on the methodology, decided on six themes for working groups (WGs) and drafted a list of research questions. Senior WG members, mostly colorectal surgeons within the ESCP, were invited based on publication records and geographical aspects. Other specialties were included in the WGs where relevant. In addition, one trainee or PhD fellow was invited in each WG. All six WGs revised the research questions if necessary, did a literature search, created evidence tables where feasible, and drafted supporting text to each research question and statement. The text and statement proposals from each WG were arranged as one document by the first and last authors before online voting by all authors in two rounds. For the second voting ESCP national representatives were also invited. More than 90% agreement was considered a consensus. The final phrasing of the statements with < 90% agreement was discussed in a consensus meeting at the ESCP annual meeting in Vienna in September 2019. Thereafter, the first and the last author drafted the final text of the guideline and circulated it for final approval and for a third and final online voting of rephrased statements. RESULTS This guideline contains 38 evidence based consensus statements on the management of diverticular disease. CONCLUSION This international, multidisciplinary guideline provides an up to date summary of the current knowledge of the management of diverticular disease as a guidance for clinicians and patients.

When the bowel meets the bladder: Optimal management of colorectal pathology with urological involvement. World J Gastrointest Surg 2020; 12:208-225.

Abstract
Fistulae between the gastrointestinal and urinary systems are rare but becoming increasingly more common in current surgical practice. They are a heterogeneous group of pathological entities that are uncommon complications of both benign and malignant processes. As the incidence of complicated diverticular disease and colorectal malignancy increases, so too does the extent of fistulous connections between the gastrointestinal and urinary systems. These complex problems will be more common as a factor of an aging population with increased life expectancy. Diverticular disease is the most commonly encountered aetiology, accounting for up to 80% of cases, followed by colorectal malignancy in up to 20%. A high index of suspicion is required in order to make the diagnosis, with ever improving imaging techniques playing an important role in the diagnostic algorithm. Management strategies vary, with most surgeons now advocating for a single-stage approach to enterovesical fistulae, particularly in the elective setting. Concomitant bladder management techniques are also disputed. Traditionally, open techniques were the standard; however, increased experience and advances in surgical technology have contributed to refined and improved laparoscopic management. Unfortunately, due to the relative rarity of these entities, no randomised studies have been performed to ascertain the most appropriate management strategy. Rectourinary fistulae have dramatically increased in incidence with advances in the non-operative management of prostate cancer. With radiotherapy being a major contributing factor in the development of these complex fistulae, optimum surgical approach and exposure has changed accordingly to optimise their management. Conservative management in the form of diversion therapy is effective in temporising the situation and allowing for the diversion of faecal contents if there is associated soiling, macerated tissues or associated co-morbidities. One may plan for definitive surgical intervention at a later stage. Less contaminated cases with no fibrosis may proceed directly to definitive surgery if the appropriate expertise is available. An abdominal approach with direct repair and omentum interposition between the repaired tissues has been well described. In low lying fistulae, a transperineal approach with the patient in a prone-jack knife position provides optimum exposure and allows for the use of interposition muscle grafts. According to recent literature, it offers a high success rate in complex cases.

Abstract
BACKGROUND Colovesical fistula (CVF) is an uncommon complication of diverticulitis. Substantial heterogeneity exists in the perioperative management of this condition. We seek to evaluate the role of bladder leak testing, closed suction drainage, prolonged bladder catheter usage, and routine postoperative cystogram in the management of CVF. STUDY DESIGN This is a retrospective study from a single academic health center investigation patients undergoing operation for diverticular CVF from 2005 to 2015 (n = 89). RESULTS Patients undergoing operative repair for diverticular CVF resection had a mortality of 4% and overall morbidity of 46%. Intraoperative bladder leak test was performed in 36 patients (40%) and demonstrated a leak in 4 patients (11%). No patients with a negative intraoperative bladder leak test developed a urinary leak. Overall, five (6%) patients developed postoperative bladder leak. Three were identified by elevated drain creatinine and two by cystogram. The diagnostic yield of routine cystogram was 3%. All bladder leaks were diagnosed between postoperative day 3 and 7. Of patients with a postoperative bladder leak, none required reoperation and all resolved within 2 months. CONCLUSIONS There is significant variability in the management of patients undergoing operation for CVF. Routine intraoperative bladder leak test should be performed. Cystogram may add cost and is low yield for routine evaluation for bladder leak after operation for CVF. Urinary catheter removal before postoperative day 7 should be considered.

Abstract
BACKGROUND Diverticular disease is the leading cause of colovaginal fistulas. Surgery is challenging given the inflammatory process that makes dissection difficult. To date, studies are small and include fistula secondary to multiple etiologies. OBJECTIVE The objectives of this study were to examine surgical outcomes of diverticular colovaginal fistulas and to identify variables associated with successful closure. DESIGN This was a retrospective study of a prospectively maintained clinical database. SETTINGS The study was conducted at a single tertiary referral center. PATIENTS Women with diverticular colovaginal fistulas, who underwent surgical repair with intent to close the fistula, were included. INTERVENTIONS Repair of colovaginal fistula through minimally invasive or open techniques was involved. MAIN OUTCOME MEASURES Successful closure of fistula, defined as resolution of symptoms and no stoma, was measured. RESULTS Fifty-two patients underwent surgical treatment of diverticular colovaginal fistula, 23 (44%) of whom underwent a minimally invasive approach (conversion rate of 22%). Ostomy construction and omental pedicle flaps were used in 28 (54%) and 38 patients (73%). Surgery was successful in 47 patients (90%). Accounting for secondary operations, ultimate success and failure rates were 49 (94.0%) and 3 (5.7%). There was no difference in postoperative morbidity between the 2 groups (5 patients with Clavien-Dindo III/IV complications in the success group versus 2 patients in the failure group; 10.6% vs 40.0%; p = 0.44). Failure to achieve fistula closure was not associated with perioperative variables, age, BMI, diabetes mellitus, ASA grade, steroid use, previous abdominal surgery or hysterectomy, use of omentoplasty, or ostomy. Patients who failed were more likely to be smokers (60.0% vs 12.8%; p = 0.03). LIMITATIONS Limitations include the retrospective design and lack of power. CONCLUSIONS Surgery is effective in achieving successful closure of diverticular colovaginal fistula. Smokers should be encouraged to stop before embarking on an elective repair. Although the use of fecal diversion and omental pedicle flaps did not correlate with success, they should be used when clinically appropriate. See Video Abstract at http://links.lww.com/DCR/A983. FÍSTULAS COLOVAGINALES DIVERTICULARES ¿QUÉ FACTORES CONTRIBUYEN AL ÉXITO DEL TRATAMIENTO QUIRÚRGICO?: La enfermedad diverticular es la causa principal de fístulas colovaginales. La cirugía es un reto dado el proceso inflamatorio que dificulta la disección. Hasta la fecha, los estudios son pequeños e incluyen fístulas secundarias a múltiples etiologías. OBJETIVO 1) Examinar los resultados quirúrgicos de las fístulas colovaginales diverticulares; 2) Identificar variables asociadas a un cierre exitoso. DISEÑO:: Estudio retrospectivo de una base de datos clínicos prospectivamente mantenida. CONFIGURACIÓN:: Centro de referencia superior. PACIENTES Mujeres con fístulas colovaginales diverticulares, que se sometieron a una reparación quirúrgica con la intención de cerrar la fístula. INTERVENCIONES Reparación de la fístula colovaginal mediante técnicas mínimamente invasivas o abiertas. MEDIDAS DE RESULTADOS PRINCIPALES Cierre exitoso de la fístula definida como resolución de los síntomas y sin estoma. RESULTADOS Cincuenta y dos pacientes se sometieron a tratamiento quirúrgico de la fístula colovaginal diverticular, 23 (44%) de los cuales se sometieron a un acceso mínimamente invasivo (tasa de conversión del 22%). La construcción de la ostomía y los pedículos omentales se utilizaron en 28 (54%) y 38 pacientes (73%), respectivamente. La cirugía fue exitosa en 47 pacientes (90%). Tomando en cuenta las operaciones secundarias, las tasas finales de éxito y fracaso fueron 49 (94.0%) y 3 (5.7%). No hubo diferencias en la morbilidad postoperatoria entre los dos grupos (5 pacientes con complicaciones de Clavien-Dindo III / IV en el grupo de éxito versus a 2 pacientes en el grupo de fracaso, 10.6% versus a 40.0%; p = 0.44). El fracaso para lograr el cierre de la fístula no se asoció con variables perioperatorios, edad, IMC, diabetes, grado ASA, uso de esteroides, cirugía abdominal previa o histerectomía, uso de omentoplastia u ostomía. Los pacientes que fracasaron eran más propensos a ser fumadores (60.0% versus a 12.8%; p = 0.03). LIMITACIONES Las limitaciones incluyen el diseño retrospectivo y la falta de poder. CONCLUSIONES La cirugía es efectiva para lograr el cierre exitoso de la fístula colovaginal diverticular. Se debe aconsejar a los fumadores a parar de fumar antes de embarcarse en una reparación electiva. Mientras el uso de desviación fecal y pedículos omentales no se correlacionó con el éxito, deberían utilizarse cuando sea clínicamente apropiado.

Abstract
Enterovesicular fistulas (EVFs) are abnormal connections between the colon and the urinary bladder. They are estimated to account for one in every 3,000 surgical hospital admissions and are rarely associated with long-standing Crohn's colitis. We present an interesting case of a 93-year-old man with a long-standing history of Crohn's colitis on mesalamine, whose mechanical fall at home lead to the discovery of a colovesicular fistula with invading urothelium concerning for squamous cell carcinoma.

Abstract
Background and Objective: Entero vesical fistulas (EVFs) are an uncommon complication mainly of diverticular disease (70%) and less commonly of Crohn's disease (10%). Only about 10% are caused by malignancies. At this time, it is unclear whether the laparoscopic approach can be routinely proposed as a safe procedure for patients with EVF. The aim of this study was to assess the feasibility and safety of laparoscopic surgery in the treatment of EVFs in patients with complicated diverticular and Crohn's disease. Methods: All patients with the diagnosis of EVF who underwent laparoscopic surgery were identified from prospective collected data based in two institutions between 2007 and 2017. Patients with malignancy were excluded. Recorded parameters included operative time, conversion to open surgery, the presence of a protective loop ileostomy, perioperative complications, number of units of blood transfused, postoperative course, and histologic findings. Results: Seventeen patients were included in the study: 10 patients with a colo-vesical fistula due to diverticular disease, and 7 patients with an ileo-vesical fistula due to Crohn's disease. There were no conversions to open surgery and none of the patients needed a protective ileostomy. The bladder was sutured in 12 patients (70%). No intra-operative complications were met, and no blood transfusions were needed; there were no anastomotic leaks, nor mortality in both groups. Conclusions: The laparoscopic approach for benign EVF in selected patients is both feasible and safe in the hands of experienced surgeons with extensive expertise in laparoscopic surgery.

Abstract
BACKGROUND Diverticular disease of sigmoid colon can rarely be complicated by a connective track to urinary bladder. Pneumaturia and fecaluria are the pathognomonic symptoms. Resection surgery is the preferred treatment to overcome the renal sequellae of the disease. The purpose of this study is to propose a guiding classification to help general surgeons during surgical management of diverticular disease complicated by sigmoidovesical fistula (SVF). PATIENTS AND METHODS The data of 40 cases with colovesical fistula due to diverticular disease of sigmoid colon were retrospectively analyzed. Clinicopathological variables, imaging reports, types of treatment and patient outcome were evaluated. RESULTS There were 36 men (90%) and four women (10%) in which the ages ranged from 32 to 79 with a mean of 58.1 years. Pneumaturia was the most common presenting symptom in 38 cases (95%) followed by urinary symptoms in 35 cases (87.5%) then fecaluria in 33 cases (82.5%). 37 patients underwent surgical resection while three patients were in poor general condition to withstand major resection. 16 patients underwent one stage resection and anastomosis, 16 patients were managed by two stage procedure and the remaining 5 patients were treated by three stages operation. CONCLUSIONS Adequately performed CT followed by colonoscopy is the mainstay for diagnosis. Type 1 SVF should be treated in a single stage by complete resection and immediate anastomosis without a stoma. Type 2 cases are best managed in two stages while those with type 3 SVF are emergently managed by three stage procedure. Treatment of type 4 should be individualized.

Abstract
OBJECTIVE Colovesical fistulas (CVF) constitute the most common type of spontaneously occurring fistulas associated with diverticular disease. One-stage laparoscopic resection has been shown to be feasible, but studies comparing this approach to open surgery are scarce. The aim of this study was to compare the clinical outcomes of open and laparoscopic surgery for CVF of diverticular origin. MATERIALS AND METHODS From January 2000 to July 2014, 37 colectomies were performed for diverticular disease-related CVF. Twenty-eight patients who underwent resection and primary anastomosis were divided in 2 groups: the laparoscopic surgery group (group A) and the open surgery group (group B). We have analyzed the following parameters: operative time, complication rate, hospital stay, recurrence, and early mortality rate. RESULTS Groups A and B were comparable in terms of age, sex, diverticulitis episodes, previous abdominal surgery, and body mass index.The mean duration of surgery was significantly shorter in group B: 175 versus 237 minutes (P=0.011). There was a faster recovery of gastrointestinal transit in group A (2 vs. 13; P=0, 0002). However, there were no significant differences between the groups with respect to serious postoperative morbidity [(Clavien-Dindo scores of 3, 4, and 5) 4 vs. 0; P=0.098)] and with respect to hospital stay (10.5 vs. 9.5 d; P=0.537). There was no recurrence during a median follow-up of 12 months. CONCLUSIONS Laparoscopic resection and primary anastomosis should be considered a safe and feasible option for the management of diverticular CVF. Despite progresses in minimally invasive colorectal surgery, the conversion rate and morbidity are still high.

Abstract
BACKGROUND The aim of treatment of patients with colovesical fistulas should be prompt elimination of the infection and the social burden. We focused on the question whether a minimally invasive surgical approach as a cooperation between surgeons and urologists is possible. This requires effective diagnostics prior to the operation. METHODS Since 2007 a total of 32 patients with the clinical suspicion of colovesical fistula have undergone extensive preoperative diagnostics. Operative treatment aimed primarily for a minimally invasive approach. In particular, the validity of preoperative diagnostics was analyzed and surgical results were characterized by clinical success, complications and long-term effects. RESULTS The medical history significant for colovesical fistula and detected urinary infection provided the best evidence for the specific diagnosis. Cystoscopy, computed tomography (CT) scan and colonoscopy were only partially effective for predicting a fistula as subsequently diagnosed by histopathological investigations. Fistulas due to diverticulitis of the sigmoid colon occurred in 28 cases, while in 3 subjects there was a gynecological and inflammatory cause (malignant tumor growth, n = 1). A laparoscopic approach achieving repair and healing of the fistula was possible in 29 cases including conversion in 3 subjects because of intraoperative complications. The remaining patients underwent conventional treatment. The disease-related complication rate as revealed during follow-up was 10%. DISCUSSION Laparoscopic repair and healing of a colovesical fistula is possible in the majority of cases by the recommended preoperative ureteral stenting. As part of diagnostic measures, the medical history significant for a fistula and detection of urinary infections are the most reliable aspects. In the case of this combination together with a further diagnostic measure, a laparoscopic approach is always recommended. The recurrency rate is 0%.

Abstract
BACKGROUND Colovaginal fistula is a rare condition associated with significant morbidity. The literature characterizing colovaginal fistula repair is sparse. We present our institution's experience treating colovaginal fistulas. METHODS A retrospective review of all patients surgically treated for colovaginal fistula between 2005 and 2015 was performed. Patient demographics, intra-operative details, and post-operative outcomes were reviewed. RESULTS We identified 27 patients with a mean age of 71 (±13) and BMI of 30 (±9). The most common etiology for fistula was diverticulitis (n = 24, 89%). A laparoscopic approach was initiated in 19 patients (70%) and an open approach for 8 (30%) with 8 patients converted from laparoscopy to open (42%). At a mean follow-up of 18 months (±21), there were no recurrences. CONCLUSION We present one of the largest series of the surgical management of colovaginal fistulas. Although our conversion rate was high, we recommend a laparoscopic approach be utilized when feasible.

Abstract
Colouterine fistula as a potential complication of chronic diverticulitis is a rare entity with less than 30 cases reported worldwide. Generally, patients require a multidisciplinary approach including a major laparotomy with hysterectomy and sigmoid colectomy, and, occasionally, temporary colostomy. We report the first attempt of a novel, minimally invasive technique for managing a case of benign colouterine fistula with single-incision laparoscopic (SIL) sigmoid colectomy and uterus preservation. A small, 3 cm incision site provided access for the whole operation, as well as played a role as the specimen extraction site. Malignant fistulas and large uterine defects may require hysterectomy, however, laparoscopic closure of uterine wall defects can be considered as a reasonable alternative in selected patients, avoiding the higher risks associated with hysterectomy and keeping fertility at younger ages. Single incision laparoscopy in complicated diverticular disease and fistula formation cases is a challenging but technically feasible option, in experienced hands.

Abstract
PURPOSE This research was conducted to compare the management and the outcome of patients with colovesical fistulae of different aetiologies. METHODS Retrospective data were collected from 2002 to 2012 and analyzed with SPSS ver. 17. Age, gender, aetiology, management, hospital stay, postoperative complications, and mortality were studied and compared among colovesical fistulae of different aetiologies. RESULTS A total of 55 patients, 46 males (84%) and 9 females (16%), with a median age of 65 years (interquartile range [IQR], 48-75 years) were studied. Diverticular disease was the most common benign cause and recto-sigmoid cancer the most common malignancy. Anterior resection and bladder repair were the most frequent operations in benign cases, as was total pelvic exenteration in the malignant group. Multiple intestinal loop involvement and subsequent resection were significantly higher in those with Crohn disease than it was in patients of colovesical fistula due to all other causes collectively (60% vs. 6%, P = 0.006). Patients with malignancy had a higher postoperative complication rate than patients who did not (12 [80%] vs. 7 [32%], P = 0.0005). Pelvic collection (11, 22%) was the most frequent early complication (predominantly in the malignant group) whereas incisional hernia (8, 22%) was the most common late complication, with a predominance in the benign group. The median hospital stay was significantly prolonged in the malignant group (32 days; IQR, 17-70 days vs. 16 days; IQR, 11-25 days; P < 0.001). CONCLUSION Despite their having similar clinical presentation, colovesical fistulae of various aetiologies differ significantly in management and outcome.

Abstract
BACKGROUND Anastomotic leakage (AL) is one of the most common and lethal complications in gastrointestinal surgery. However, the relationship between AL risk and diabetes mellitus (DM) remains ambiguous. This meta-analysis was to evaluate the association between DM and AL risk in patients after gastrointestinal resection. METHODS Odds ratios (OR) estimate with their corresponding 95% confidence intervals (CIs) were combined and weighted to produce pooled OR using the fixed-effects model. Relative risks were calculated in subgroup analysis of prospective studies. We calculated publication bias by Begg rank correlation test and Egger linear regression test. RESULTS DM was significantly and independently associated with an increased risk of AL morbidity in colorectal patients, 1.661 times in total patients (95% CIs = 1.266-2.178), 1.995 times in a subgroup of case-control studies, 1.581 times in cohort investigations, 1.688 times in retrospective trials, and 1.562 times in prospective designs. After adjusting for the factor of obesity and/or body mass index in the subgroup analyses of colorectal surgery, DM patients without obesity experienced a significantly increased risk of AL (OR = 1.572, 95% CIs = 1.112-2.222). Furthermore, when obesity had not been adjusted, DM patients endured a dramatical increase of AL incidence (OR = 1.812, 95% CIs = 1.171-2.804). Perforation incidence after gastric resection showed borderline association with DM (OR = 2.170, 95% CIs = 0.956-4.926). CONCLUSIONS The present meta-analysis provides strong evidence for the first time that DM is significantly and independently associated with an increased risk of AL mortality in colorectal surgery.

Abstract
Colovesical fistulas secondary to diverticular disease may be considered a contraindication to the laparoscopic approach. The feasibility of laparoscopic management of complicated diverticulitis and mixed diverticular fistulas has been demonstrated. However, few studies on the laparoscopic management of diverticular colovesical fistulas exist. A retrospective analysis was performed of 15 patients with diverticular colovesical fistula, who underwent laparoscopic-assisted anterior resection and bladder repair. Median operating time was 135 minutes and median blood loss, 75 mL. Five patients were converted to an open procedure (33.3%) with an associated increase in hospital stay (P = 0.035). Median time to return of bowel function was 2 days and median length of stay, 6 days. Overall morbidity was 20% with no major complications. There was no mortality. There was no recurrence during median follow-up of 12.4 months. These results suggest that laparoscopic management of diverticular colovesical fistulas is both feasible and safe in the setting of appropriate surgical expertise.

Abstract
Colovesical fistulas originating from complicated sigmoid diverticular disease are rare. The primary aim of this review was to evaluate the role of laparoscopic surgery in the treatment of this complication. The secondary aim was to determine the best surgical treatment for this disease. A systematic search was conducted for studies published between 1992 and 2012 in PubMed, the Cochrane Register of Controlled Clinical Trials, Scopus, and Publish or Perish. Studies enrolling adults undergoing fully laparoscopic, laparoscopic-assisted, or hand-assisted laparoscopic surgery for colovesical fistula secondary to complicated sigmoid diverticular disease were considered. Data extracted concerned the surgical technique, intraoperative outcomes, and postoperative outcomes based on the Cochrane Consumers and Communication Review Group's template. Descriptive statistics were reported according to the PRISMA statement. In all, 202 patients from 25 studies were included in this review. The standard treatment was laparoscopic colonic resection and primary anastomosis or temporary colostomy with or without resection of the bladder wall. Operative time ranged from 150 to 321 min. It was not possible to evaluate the conversion rate to open surgery because colovesical fistulas were not distinguished from other types of enteric fistulas in most of the studies. One anastomotic leak after bowel anastomosis was reported. There was zero mortality. Few studies conducted follow-up longer than 12 months. One patient required two reoperations. Laparoscopic treatment of colovesical fistulas secondary to sigmoid diverticular disease appears to be a feasible and safe approach. However, further studies are needed to establish whether laparoscopy is preferable to other surgical approaches.

Abstract
BACKGROUND Various conditions lead to the development of colonic fistulas. Contemporary surgical data is scarce and it is unclear whether advances in surgical care have impacted outcome. The aim of the present study was to review the short- and long-term outcome of patients treated surgically for colonic fistula over an 8-year period at a tertiary institution. METHODS A retrospective review was performed, focusing on the type of operative interventions, short- and long-term complications, length of hospital stay, readmission rate, mortality rate, and fistula recurrence. RESULTS Forty-five patients were treated for colonic fistula. The most common etiology was diverticulitis (74%). Fistula type was colovesical (58%), colocutaneous (18%) and colovaginal (15%). Laparoscopic resection was performed in 42% of cases. An intraoperative complication occurred in 4%. A primary anastomosis was performed in 96% of patients and 10 (23%) had a temporary stoma. Median length of hospital stay was 6 days. Postoperative complications were common (47%) and wound infection was noted in 20% of patients. The readmission rate was 29% and the 90-day mortality was 4%. All patients healed their fistula with no recurrences noted during a median follow-up of 37 months. CONCLUSIONS Surgical intervention healed the majority of patients with colonic fistula. However postoperative complications were common and readmission occurred in one-third of the cases. Laparoscopic excision was feasible in nearly half of the patients.
