Duodenocolic and Cholecystocolonic Fistula: A Case Report of an Unusual Presentation.

Laparoscopic cholecystectomy is the established standard of care for addressing symptomatic gallstones, typically representing a straightforward and uncomplicated surgical procedure. However, patients exhibiting variant anatomy or local inflammation can present challenges to the surgeon, potentially leading to complications. In this context, we present the case of a 55-year-old woman who underwent a laparoscopic cholecystectomy for symptomatic gallstone disease at a different medical facility. Postoperatively, she was diagnosed with a case of duodenocolic fistula and cholecystocolonic fistula. Conservative treatment ensued with intravenous antibiotic administration, as well as enteral and parenteral feeding. Diagnosing cholecystocolonic fistula before surgery proves challenging, even with modern diagnostic and imaging tools. Despite its significance, there is limited information in the literature regarding the management of this infrequent finding. The approach to diagnosis and management is elaborated upon in the case report.

Cholecystocolonic fistula in exacerbated chronic cholecystitis: A case report.

The cholecystocolonic fistula (CCF) is an atypical variant of biliary disease, and it is the second most common intestinal fistula after cholecystoduodenal fistula. Intraoperative diagnosis is frequent, which implies challenging surgical management, especially in patients, often aged, with comorbidities. The rarity of this condition, atypical and various presentation, diagnostic and management complexity, makes it a unique surgical entity. We report our experience of an 84-year-old man with a history of chronic cholecystitis who presented with nonspecific symptoms. The imaging tests aroused the suspicion of gallbladder-colic fistula in the preoperative diagnosis, facilitating the subsequent surgical treatment that confirmed the diagnosis.

An unusual case of gallstone ileus within the cecum and ascending colon: a case report.

Gallstone ileus is a rare cause of intestinal obstruction. Due to long-standing inflammation of the gallbladder, fistulization can occur within nearby structures, most commonly to the duodenum or hepatic flexure of the colon. Through these fistulas, a stone can migrate and result in a small bowel obstruction or a large bowel obstruction. This case exemplifies the diagnosis and treatment of gallstone ileus, along with potential complications due to stone migration. Early recognition and treatment of gallstone ileus is important, as stone migration can lead to increased mortality with delayed diagnosis.

Colonic gallstone ileus: a systematic literature review with a diagnostic-therapeutic algorithm.

Rare complication of gallstone disease is gallstone ileus. The common location is the small intestine, followed by the stomach. The rarest location is colonic gallstone ileus (CGI). To summarize and define the most appropriate diagnostic methods and therapeutic options for CGI based on the paucity of published data. Literature searches of English-, German-, Spanish-, Italian-, Japanese-, Dutch- and Portuguese language articles included and Italian-language articles using PubMed, EMBASE, Web of Science, The Cochrane Library, and Google Scholar. Additional studies were identified from the references of retrieved studies. 113 cases of CGI were recorded with a male to female patient ratio of 1:2.9. The average patient age was 77.7 years (range 45-95 years). The usual location of stone impaction was the sigmoid colon (85.8%), followed by a descending colon (6.6%), transverse colon (4.7%), rectum (1.9%), and lastly, ascending colon (0.9%). Gallstones ranged from 2 to 10 cm. The duration of symptoms was variable (1 day to 2 months), with commonly reported abdominal distension, obstipation, and vomiting; 85.2% of patients had previous biliary symptoms. Diverticular disease was present in 81.8% of patients. During the last 23 years, CT scan was the most common imaging method (91.5%), confirming the ectopic gallstone in 86.7% of cases, pneumobilia in 65.3%, and cholecytocolonic fistula in 68%. The treatment option included laparotomy with cololithotomy and primary closure (24.7%), laparotomy and cololithotomy with diverting stoma (14.2%), colonic resection with anastomosis (7.9%), colonic resection with a colostomy (12.4%), laparoscopy with cololithotomy with primary closure (2.6%), laparoscopy with cololithotomy with a colostomy (0.9%), colostomy without gallstone extraction (5.3%), endoscopic mechanical lithotripsy (success rate 41.1%), extracorporeal shock wave lithotripsy (1.8%). The cholecystectomy rate was 46.7%; during the initial procedure 25%, and as a separate procedure, 21.7%; 53.3% of patients had no cholecystectomy. The survival rate was 87%. CGI is the rarest presentation of gallstone ileus, mainly in women over 70 years of age, with gallstones over 2 cm, and predominantly in the sigmoid colon. Abdominal CT is diagnostic. Nonoperative treatment, particularly in subacute presentations, should be the first-line treatment. Laparotomy with cololithotomy or colonic resection is a standard procedure with favorable outcomes. There are no robust data on whether primary or delayed cholecystectomy is mandatory as a part of CGI management.

Single stage surgical management of a sigmoid gallstone ileus case.

Bowel obstruction/ileus is a relatively common occurrence in surgical practice with a predictable clinical presentation and management course. Rarely are these cases found consistent with gallstone etiology. Known as gallstone ileus (GI), this uncommon presentation is found primarily in elderly females (age > 65 years old) with multiple comorbid conditions; usually with coinciding presence of a cholecystoenteric fistula. Surgical management remains controversial due to the rarity of presentation and complexity of related pathological process. We present a case of a 69-year-old female who presented with typical signs/symptoms of bowel obstruction but found to have sigmoid GI on computed tomography imaging evaluation. A single stage exploratory laparotomy with simple enterolithotomy was performed with a positive outcome and uncomplicated postoperative recovery. The primary goal in reporting this case is to continue emphasizing the efficacy of a single stage simple enterolithotomy as the most ideal surgical management of this rare condition.

Cholecystocolonic fistula following endoscopic ultrasound-guided gallbladder drainage for stump cholecystitis.

Cholecystocolonic fistulas are a rare sequela of gallstone disease. Presenting symptoms are variable but a triad of chronic diarrhea, vitamin K malabsorption, and pneumobilia has been proposed. If untreated, recurrent biliary sepsis can occur with substantial morbidity and mortality. Definitive management is surgical although endoscopic treatment has been described in nonsurgical patients. We present a case of a cholecystocolonic fistula following transgastric endoscopic ultrasound-guided gallbladder drainage with a lumen-apposing metal stent for stump cholecystitis. The patient's presenting symptom was diarrhea. Upper endoscopy and cholecystoscopy 4 weeks following gallbladder drainage revealed a cholecystocolonic fistula. The cholecystogastric tract was closed through the scope clips. The patient had no episodes of cholangitis and had a patent biliary tree with a prior biliary sphincterotomy so clinical observation was chosen. Colonoscopy 1 month later confirmed the closure of the fistula and the patient had a resolution of diarrhea. Our case highlights a novel adverse event of endoscopic ultrasound-guided gallbladder drainage caused by direct pressure of the lumen apposing metal and double pigtail stents on an already inflamed gallbladder wall. Endoscopic therapies that aid in transcapillary biliary drainage are viable alternatives to surgery and can result in fistula closure.

Cholecystoenteric fistula in a patient with advanced gallbladder cancer: A case report and review of literature.

BACKGROUND: Cholecystoenteric fistula (CEF) involves the formation of a spontaneous anomalous tract between the gallbladder and the adjacent gastrointestinal tract. Chronic gallbladder inflammation can lead to tissue necrosis, perforation, and fistulogenesis. The most prevalent cause of CEF is chronic cholelithiasis, which rarely results from malignancy. Because the symptoms and laboratory findings associated with CEF are nonspecific, the condition is often misdiagnosed, presenting a challenge to the surgeon when detected intraoperatively. Therefore, a preoperative diagnosis of CEF is crucial. CASE SUMMARY: We present the case of a 57-year-old male with advanced gallbladder cancer (GBC) who arrived at the emergency room with persistent vomiting, abdominal pain, and diarrhea. An abdominopelvic computed tomography scan revealed a contracted gallbladder with bubbles in the fundus connected to the second portion of the duodenum and transverse colon. We suspected that GBC had invaded the adjacent gastrointestinal tract through a cholecystoduodenal fistula (CDF) or a cholecystocolonic fistula (CCF). He underwent multiple examinations, including esophagogastroduodenoscopy, an upper gastrointestinal series, colonoscopy, and magnetic resonance cholangiopancreatography; the results of these tests confirmed a diagnosis of synchronous CDF and CCF. The patient underwent a Roux-en-Y gastrojejunostomy and loop ileostomy to address the severe adhesions that were previously observed to cover the second portion of the duodenum and hepatic flexure of the colon. His symptoms improved with supportive treatment while hospitalized. He initiated oral targeted therapy with lenvatinib for further anticancer treatment. CONCLUSION: The combination of imaging and surgery can enhance preoperative diagnosis and alleviate symptoms in patients with GBC complicated by CEF.

Robotic Diagnosis and Management of Acute Cholecystocolonic Fistula.

Cholecystocolonic fistula (CCF) is a rare complication of biliary tract disease. Increased use of imaging has aided in diagnosing these fistulae preoperatively and has established laparoscopy as a safe alternative to laparotomy. Here, we present a 79-year-old male who presented to the emergency room with abdominal pain and was diagnosed with choledocholithiasis. CT scan revealed a CCF, and he underwent endoscopic retrograde cholangiopancreatography (ERCP). He was followed closely to allow maturation of the fistula, and then, da Vinci® Xi robotic cholecystectomy and ligation were performed. Although current comparisons to laparoscopy have yet to demonstrate a clinical advantage, robotic assistance enhances dexterity, visualization, and ergonomics. Our case is one of the first documented successful operative management of CCF using the da Vinci® Xi robot.

Large bowel obstruction secondary to gallstones.

Gallstone ileus is a rare complication of cholelithiasis, representing 1% of bowel obstructions. The usual site of obstruction is the ileocecal valve, though other sites have been reported. Here, we present two cases of gallstone ileus within the distal colon requiring surgical intervention. Two elderly females presented with vague abdominal symptoms secondary to large bowel obstruction from gallstone impaction. Both underwent attempted endoscopic retrieval without success. Patient 1 required laparoscopy converted to exploratory laparotomy with colotomy and removal of the stone. Patient 2 required partial colectomy and end colostomy formation due to acute sigmoid inflammation. Gallstone ileus is a rare cause of intestinal obstruction, though incidence increases with age. Cholecystocolonic fistulas allow stones to bypass the ileocecal valve, with the potential for impaction in the colon at the site of a stricture or tortuosity. Surgical intervention may be required in cases not amenable to successful endoscopic retrieval.

Cholecystocolonic fistula as an uncommon cause of diarrhea: a case-report and review of the literature.

Bilio-enteric fistulization is the aberrant connection between the biliary and luminal digestive tracts. The cholecystocolonic fistula (CCF) is the second most common bilio-enteric fistula (comprising 20% of cases), after the cholocystoduodenal fistula (comprising 70% of all cases). A CCF may result from malignancy or more benign etiologies, such as gallstones, and is thought to arise from a chronic inflammatory cadence of tissue necrosis, tissue perforation, and fistula creation. The combination of chronic watery diarrhea, vitamin K malabsorption, and radiological evidence of pneumobilia in a patient with history of gallstone disease has been suggested as a pathognomonic triad of CCF. Here, we present a case of a 62-year-old woman exhibiting this triad, who was found to have a CCF as a result of chronic gallstone-related disease. Recognition of this rare etiology of chronic diarrhea can enhance clinicians' diagnostic appraisal and management of this common chief complaint.

Laparoscopic management of cholecystocolonic fistula: A case report and a brief literature review.

INTRODUCTION: Cholecystoenteric fistula is a rare and late complication of cholelithiasis. The clinical presentation is mostly chronic and is not distinguishable from the dyspeptic symptoms of non-complicated cholelithiasis. For this reason, the preoperative diagnosis is difficult and uncertain, and it is often made up primarily intraoperatively and incidentally during cholecystectomy. In this article, we report a case of cholecystocolonic fistula management by laparoscopic approach. PRESENTATION OF CASE: We studied a 64 years old male patient with fever of an unknown origin for two months and abdominal pain. He underwent a contrast enhanced CT abdominal scan that showed a sclerotic gallbladder with a disorganized fluid collection. The colonoscopy identified a cholecystocolonic fistula with hepatic flexure. A laparoscopic cholecystectomy was performed to repair the colonic wall with intra-corporeal sutures. DISCUSSION: Thanks to the advancements in CT scan's resolution and the application of endoscopic technology such as ERCP or colonscopy, preoperative diagnosis of cholecystoenteric fistula has been greatly improved. In addition, cholecystoenteric fistula has been successfully managed laparoscopically with laparoscopic cholecystectomy and closure of the fistula tract. CONCLUSION: The laparoscopic management of cholecystoeneteric fistula is a feasible and safe procedure but the operative strategy should be individualized on diagnosis, patient characteristics, availability of resources and experience of surgical team.

Cholecystocolonic fistula: A rare case report of Mirizzi syndrome.

INTRODUCTION: Mirizzi syndrome is a rare complication of gallstone disease that more rarely is associated with the formation of cholecystoenteric fistula. PRESENTATION OF CASE: The patient presented with a five-day history of abdominal pain in the right upper quadrant (RUQ), nausea, and emesis. Further ultrasound (US) imaging demonstrated a large gallstone with associated thickened gallbladder with pericholecystic fluid. Computed tomography (CT) imaging, preoperative Hepatobiliary Scintigraphy and Endoscopic Retrograde Cholangiopancreatography (ERCP) displayed findings consistent with a Csendes type IV Mirizzi syndrome associated with cholecystocolonic fistula. Description of surgical approach, management and outcome is presented. DISCUSSION: Surgical management of Mirizzi syndrome varies by classification of its severity. Open operation is preferred in cases with severe inflammation and concern for malignancy. The patient underwent a cholecystocolonic fistula takedown. A cholecystectomy was attempted though aborted due to concerns of malignancy. Biopsies returned negative for malignancy and the patient demonstrated findings on ERCP consistent with Mirizzi syndrome. Stenting of the common bile duct (CBD) was performed with ERCP and later the patient underwent an open biliary exploration with subsequent choledochotomy, biliary stone removal, and primary closure with interrupted sutures using remnant gallbladder wall flaps. CONCLUSION: To our knowledge, Mirizzi syndrome with concurrent cholecystocolonic fistula is exceedingly rare with a paucity of reports within the literature. Our report discusses principles of management of Mirizzi syndrome as well as best practices of surgical management for Mirizzi syndrome with concurrent cholecystocolonic fistula.

Cholecystocolonic Fistula.

Cholecystocolonic fistula (CCF) is a rare complication of gallstone disease with a variable clinical presentation. It is difficult to diagnose CCF pre-operatively despite modern diagnostic and imaging modalities as they are often asymptomatic or incidentally discovered, often peri-operatively. However, management of this uncommon yet important finding is not very well described in the literature. The most common fistula is the cholecystoduodenal fistula, followed by the cholecystocolonic fistula; the cholecystogastric fistula is reportedly the least commonly reported. We report our experience with three cases of cholecystocolonic fistula discovered on imaging which were subsequently confirmed through surgery.

The use of the somatostatin analogue octreotide for the conservative management of symptomatic cholecystocolonic fistula: a case report.

An 84-year-old woman presented with acute worsening of diarrhoea for a few weeks, with a background of chronic diarrhoea over the past 12 months accompanied by weight loss. Computed tomography during this admission revealed air in the biliary tree and resolution of gallstones in keeping with a cholecystocolonic fistula. Owing to her comorbidities, surgical management was deemed not to be the best option. She was trialled on octreotide, a somatostatin analogue, which effectively resolved her symptoms. This case presents an effective and novel method of managing cholecystocolonic fistulas conservatively in a patient where medical therapy is the ceiling of care.

Gallstone ileus of the sigmoid colon caused by cholecystocolonic fistula: A case report.

INTRODUCTION: A cholecystocolonic fistula (CCF) is a late complication following repeated episodes of chronic inflammation of the gallbladder in contact with the hepatic flexure, and it might cause a biliary ileus in the colon, causing an intestinal obstruction, and if left untreated, a life threatening disease. PRESENTATION OF CASE: a 49-year-old female patient presented with abdominal pain and bowel obstruction due to a gallstone impaction on the sigmoid colon as consequence of a cholecystocolonic fistula. An enterolithotomy was performed, and the patient evolved favorably. She was discharged without complications on the 5th Postoperative day (POD). DISCUSSION: Clinical signs of CCF are usually minimal, and a preoperative diagnostic of CCF is rare, and it often presents with abdominal pain, nausea, vomiting, diarrhea, weight loss, and malabsorption. In the vast majority of patients presenting with CCF and biliary ileus, the stone is located within the sigmoid colon, accompanied with a concomitant disease at this point, with diverticulosis being the most common occurrence. CONCLUSION: A cholecystocolonic fistula with a gallstone colonic ileus must be suspected in an elderly, and female, patient presenting with cholelithiasis and with intestinal obstruction. Treatment should not be delayed, and correction of the intestinal obstruction ought to be the basis of the treatment.

Management dilemma of cholecysto-colonic fistula: Case report.

INTRODUCTION: Cholecystocolonic fistula is a rare condition and is found in roughly 1 in every 10,000. It represents 6.3% to 26.5% of all cholecystenteric fistulas (Chowbey et al., 2006; Angrisani et al., 2001; Yamashita et al., 1997). Cholecystocolonic fistula is the second most common intestinal fistula after cholecystoduodenal fistula (Costi et al., 2009). Rarity of this condition, atypical presentation, diagnostic and management challenges, makes it a unique surgical entity. CASE PRESENTATION: A 77-year old male presented with progressive abdominal distension and diarrhea. After initial evaluation, a cholecystocolonic fistula was suspected. Further diagnostic studies including Hepatobiliary Imino-Diacetic Acid (HIDA) scan and Endoscopic Retrograde Cholangiography (ERC) revealed complete occlusion of the cystic duct that could not be relieved. Shortly after, the patient developed septic shock likely of biliary origin and required an urgent open partial cholecystectomy and segmental resection of the involved colonic segment. DISCUSSION: In this particular case, the acute presentation together with the inflammatory features around the gallbladder pointed toward an acute inflammatory process and therefore we have tried to delay any operative intervention to allow the inflammation to subside and avoid operating in an inflamed field. Furthermore, our aim was to relieve any sort of biliary obstruction to allow the fistula -if present- to heal by minimizing bile flow through the fistula. Relieving biliary obstruction was not successful in our patient. CONCLUSION: Based on our experience with this particular case, we could safely conclude that an operation for cholecystocolonic fistula presence in the setting of biliary obstruction that failed decompressive attempts should be performed in an urgent fashion to avoid biliary sepsis development.
