A little goes a long way: A comparison of enterolithotomy versus single-stage cholecystectomy in the management of gallstone ileus

INTRODUCTION

Gallstone ileus is an infrequent complication of cholelithiasis with no specific guidelines for its management. This study aims to compare the outcomes of patients with gallstone ileus managed with both enterolithotomy with cholecystectomy (EL-CCY) versus those managed with enterolithotomy (EL) only.

METHODS

In this retrospective analysis of 2011-2017 Nationwide Readmissions Database, all patients with an index admission diagnosis of gallstone ileus were included. Patients were stratified based on the type of intervention received for gallstone ileus into those who underwent EL-CCY and those who underwent EL alone and compared. Primary outcomes were in-hospital complications (surgical site infections, sepsis, pneumonia, cardiac arrest, deep vein thrombosis, intestinal obstruction) and mortality. Secondary outcomes were hospital length of stay, hospital costs, and readmissions rate and cause of readmissions. Multivariable logistic regression analysis was performed.

RESULTS

A total of 1,960 patients were identified. The mean age was 67 years and 67% were female. Two hundred eighty-nine patients (14.7%) were managed with EL-CCY, whereas 1,671 patients (85.3%) underwent EL only. Overall, the readmission rate was 4.8%, whereas mortality was 4.2%. There was no significant difference between groups in terms of index-admission complications (24.8% vs. 21.7%, p = 0.415), mortality (6.2% vs. 3.9%, p = 0.068), rates of readmission (3.5% vs. 5.1%, p = 0.22), and cause of readmission ( p > 0.05). Enterolithotomy and cholecystectomy group had significantly longer hospital length of stay (10 vs. 8 days, p < 0.001) and median hospital costs ($70,959 vs. $52,147, p < 0.001). On multivariable logistic regression analysis, female sex was a predictor of undergoing EL-CCY, whereas increasing age and higher grade of all-patient redefined diagnosis-related groups risk of mortality were independently associated with lower odds of undergoing EL-CCY.

CONCLUSION

Our findings suggest no difference between EL compared with EL-CCY in terms of complications, readmissions, and mortality. However, patients managed with EL-CCY had a longer hospital stay and higher hospital costs compared with EL. Further prospective studies are needed to validate these findings and develop management protocols for gallstone ileus.

Gall Stone Ileus and Recurrence: Management Dilemma for the Operating Surgeon

Gallstone ileus (GSI) is a rare complication of gallstone disease. It occurs as a result of the passage of a stone from the biliary tract into the gastrointestinal tract via an abnormal pathway (bilio-enteric fistula). Chronic inflammatory processes result in gall bladder adhering and subsequently eroding into the intestines, leading to a fistula. It is a surgical emergency seen in the elderly who often present as being unwell, with abdominal pain, distension, and vomiting. Imaging such as a CT scan is diagnostic in confirming small bowel obstruction. Management usually involves relief of obstruction by removing the impacted gallstone. Despite surgical intervention, a small proportion of patients develop recurrent symptoms or recurrent gallstone ileus, usually within a few weeks of initial presentation. The recurrence of symptoms during index admission is extremely rare and can be challenging to diagnose and manage. The morbidity and mortality remain high in elderly patients. We report an 89-year-old patient who presented with small bowel obstruction. The CT scan confirmed gallstone ileus as a result of a stone impacted in the mid-small bowel. The patient had a laparotomy with extraction of the stone. No migrating stones were felt proximally. Five days postoperatively, he developed recurrent gallstone ileus confirmed on a CT scan and had to undergo another surgery to relieve the obstruction. We aim to investigate various management strategies for recurrent gallstone ileus, ranging from the commonly practiced approach of simple stone extraction to more definitive surgical interventions, including fistula repair, which may provide a more comprehensive solution.

Gallstone Ileus as an Occult Cause of Small Bowel Obstruction and Subsequent Large Bowel Obstruction: A Report of a Rare Case

Gallstone ileus, a rare cause of mechanical bowel obstruction, occurs due to the formation of a cholecystenteric fistula allowing gallstones to migrate into the gastrointestinal tract. The condition occurs mostly in elderly patients, particularly women, and carries a significant mortality risk due to delayed diagnosis. This case report discusses a 77-year-old female patient with a history of chronic medical conditions, who self-presented with periumbilical pain, nausea, and reduced bowel movements. Initial imaging revealed pneumobilia and small bowel obstruction, leading to a diagnosis of partial obstruction attributed to adhesions. Despite surgical intervention and temporary symptom relief, the patient's condition deteriorated due to a subsequent colonic obstruction. The case was complicated by delayed recognition of gallstone ileus, as imaging initially misinterpreted the obstructive mass as a "stool ball" rather than a gallstone. Following diagnostic laparoscopy and subsequent exploratory surgeries, the patient was found to have a gallstone impacted in the rectum, leading to colonic ischemia and perforation. This resulted in progressive renal failure, respiratory failure, and ultimately, the patient's death in hospice care. This case underscores the diagnostic challenges of gallstone ileus and highlights two key delays: misattribution of obstructive symptoms to adhesions and failure to recognize colonic obstruction due to gallstone ileus. Early use of contrast-enhanced imaging and a high index of suspicion are crucial for timely diagnosis. This case emphasizes the importance of thorough inspection of the small bowel and ileocecal region during laparoscopy and the need for careful evaluation of imaging findings to improve patient outcomes in gallstone ileus cases.

Laparoscopic-Assisted Enterolithotomy for Recurrent Gallstone Ileus: A Case Report

Gallstone ileus is the mechanical obstruction of the bowel due to gallstone impaction. It forms when a fistula is created between the gallbladder and the gastrointestinal tract, which can result in small bowel obstruction. Its surgical management ranges from enterolithotomy, cholecystectomy, and fistula closure performed together (one-stage) or performed separately (two-stage), while some patients undergo simple enterolithotomy. Emergency surgery with open enterolithotomy, with or without biliary tract surgery, has been replaced by laparoscopic-assisted enterolithotomy as a safer and more rapid procedure. This report is of a 68-year-old woman treated with laparoscopic-assisted enterolithotomy for gallstone ileus which recurred. A 68-year-old woman with type 2 diabetes mellitus, hypertension, breast cancer, and end-stage renal disease on hemodialysis presented with a gallstone ileus and was surgically managed with successful laparoscopic-assisted enterolithotomy. Seven days after the initial surgery, she again presented with gallstone ileus requiring reoperation. A repeat laparoscopic-assisted enterolithotomy was performed with no complications and full resolution of her symptoms. Operative management of gallstone ileus and subsequent recurrence continues to be highly debated. With no randomized studies and limited data, there is no current gold standard surgical procedure for either setting. Simple laparoscopic-assisted enterolithotomy is the favored surgical technique as it is associated with decreased morbidity, mortality, operative time, and complications. This report demonstrates that a CT scan is crucial in differentiating recurrent gallstone ileus from postoperative ileus, with a repeat laparoscopic-assisted enterolithotomy providing a safe and effective treatment option. Moreover, patient follow up is essential for monitoring symptom resolution.

Small bowel obstruction secondary to gallstone ileus: An unusual presentation of cholelithiasis

INTRODUCTION AND IMPORTANCE

Gallstone ileus remain a rare but significant cause of small bowel obstruction, especially in the elderly population. It is associated with high mortality due to nonspecific symptoms and delayed diagnosis.

CASE PRESENTATION

A 69-year-old male with a history of cholelithiasis presented with symptoms and signs suggestive of small bowel obstruction. Computed tomography (CT) scan showed pneumobilia, and small bowel obstruction, suggestive of gallstone ileus. Initial management involved exploratory laparotomy with enterotomy and gallstone removal followed by cholecystectomy and fistula closure three months later.

CLINICAL DISCUSSION

Gallstone ileus results from large gallstones causing mechanical intestinal obstruction, often via a cholecysto-intestinal fistula. CT scans are crucial for diagnosis, with surgical options for better patients' outcomes. Management of gallstone ileus involves removing the obstruction and repairing the cholecysto-intestinal fistula, but surgical approaches vary based on patient factors.

CONCLUSION

Surgeons should be aware of the variable clinical presentations and the rationale behind choosing either a one-stage or staged surgical approach, particularly in managing patients with fistulas or severe adhesions.

Interval robotic cholecystoduodenal fistula repair and cholecystectomy for gallstone ileus: a case report

Gallstone ileus is an uncommon pathology that often requires surgery in the acute setting to address the bowel obstruction, followed by definitive biliary management. Sparse literature cites the use of robotic technique in this setting. We present the case of an 86-year-old female with an independent functional status and a history of medically-managed cholecystitis, who previously declined cholecystectomy. Years later, she presented acutely with a small bowel obstruction secondary to gallstone ileus. At that time, she underwent a diagnostic laparoscopy, small laparotomy, and enterotomy for extraction of her gallstone. She returned 7 months later for an interval elective robotic-assisted cholecystectomy and repair of a cholecystoduodenal fistula. The duodenotomy was repaired in two layers with absorbable suture. Postoperatively, an upper gastrointestinal study showed normal passage of contrast without leakage. She recovered well, and shortly after returned to her baseline functional status.

Intestinal obstruction induced by gallstone migration through unusual location of a cholecystogastric fistula: A rare case report

INTRODUCTION

Gallstone ileus is a rare condition resulting from cholelithiasis, associated with the formation of a fistula between the gallbladder and the intestinal tract. It is responsible for less than 0.1 % of cases of mechanical bowel obstruction.

PRESENTATION OF CASE

A 54-year-old male with hypertension presented with symptoms of intestinal obstruction, including inability to pass stool, anorexia, abdominal pain, vomiting, and oliguria. Physical examination revealed epigastric tenderness and a distended abdomen without jaundice. Laboratory tests indicated mild anemia. The patient initially refused any surgical interventions, so he was placed on conservative treatment for 24 h. Subsequently, an emergency exploratory open laparotomy was performed, revealing a gallstone causing small bowel obstruction. A constricted ileal loop, 15 cm in length, with stone impaction was resected, and an end-to-end anastomosis was performed. A cholecystogastric fistula was identified and repaired, and a retrograde cholecystectomy was performed. The patient recovered without complications.

DISCUSSION

Gallstone ileus occurs when a fistula develops between the gallbladder and the intestinal tract. Notably, the presence of a fistula connecting the gallbladder and stomach ranges from 0 % to 13.3 %. Cholecystoenteric fistulas (CEFs) typically occur in elderly women in their seventh or eighth decade of life. Diagnosis often relies on CT scanning, and surgical intervention remains the primary treatment. Interestingly, despite improved awareness and imaging techniques, some cases are still discovered incidentally during surgery.

CONCLUSION

This case highlights the diagnostic and therapeutic challenges posed by gallstone ileus, and emphasizes the importance of considering gallstone-related disorders in differential diagnoses for acute abdominal obstruction.

Gallstone ileus: report of two cases and a mini literature review

Gallstone ileus is a relatively rare complication of cholelithiasis, and an uncommon cause of small bowel obstruction most commonly seen in elderly and debilitated people with associated comorbidities. Symptoms of gallstone ileus are insidious and may be vague while the delay in diagnosis results in a high mortality rate. Herein we report two cases of gallstone ileus in elderly patients with complex medical history who presented at the emergency department with abdominal pain and distension, vomiting and fluid/electrolyte disorders due to cholecysto-enteric fistula and bowel obstruction.

Balancing Urgency and Strategy in the Surgical Management of a Complex Case of Gallstone Ileus: A Surgical-Video-Based Case Report of a 60-Year-Old Female

Gallstone ileus is an uncommon but potentially life-threatening complication of gallstone disease, characterized by the obstruction of the gastrointestinal tract by a gallstone, typically at the ileocecal valve. This condition predominantly affects elderly patients and carries a high risk of morbidity and mortality due to delayed diagnosis and the complexity of associated comorbidities. We report the case of a 60-year-old woman with a history of hypertension and cholelithiasis who presented with a four-day history of intermittent epigastric pain, nausea, vomiting, and an inability to pass stool or flatus. Initial imaging studies, including ultrasonography and computed tomography, revealed a biliary-enteric fistula with a large obstructing gallstone at the ileocecal valve. Despite conservative management with intravenous fluids, nasogastric tube suction, and antibiotics, the patient's symptoms persisted, necessitating surgical intervention. A midline laparotomy was performed, during which the gallstone was successfully removed via enterotomy. The patient recovered without complications and was discharged in stable condition. The complexity of management, particularly in elderly patients with multiple comorbidities, necessitates careful consideration between the one-stage and two-stage surgical approaches. In this case, the decision to perform an enterotomy without immediate cholecystectomy reflects a two-stage strategy, aimed at minimizing operative risk while addressing the immediate obstruction. This approach underscores the need for individualized management plans, where the choice between one-stage and two-stage surgery is guided by the patient's overall clinical status.

Management of complicated Bouveret's syndrome

Bouveret's syndrome is an uncommon cause of gastric outlet obstruction caused by the impaction of large gallstones in the duodenal lumen. The gallstones pass into the duodenal lumen through a cholecystogastric or a cholecystoduodenal fistula. Endoscopic retrieval with or without lithotripsy is the first line of management, often with variable success. We present a case of a woman in her 70s who presented with signs of gastric outlet obstruction and was diagnosed with Bouveret's syndrome with a 5 cm diameter gallstone in the third part of her duodenum. Following several unsuccessful attempts of endoscopic extraction, she underwent successful jejunal enterotomy with fragmentation and extraction of the calculus using an Allis tissue holding forceps. Postoperative recovery was uneventful.

The Multifaceted Impact of Gallstones: Understanding Complications and Management Strategies

Gallstones, or cholelithiasis, represent a prevalent gastrointestinal disorder characterized by the formation of calculi within the gallbladder. This review aims to provide a comprehensive analysis of the complications associated with gallstones, with a focus on their pathophysiology, clinical manifestations, diagnostic methodologies, and management strategies. Gallstone-related complications encompass a broad spectrum, including biliary colic, acute cholecystitis, choledocholithiasis, acute pancreatitis, and cholangitis. The pathogenesis of these complications primarily involves biliary obstruction and subsequent infection, leading to significant morbidity and potential mortality. Diagnostic evaluation of gallstone complications employs various imaging techniques, such as ultrasonography, magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP), each with distinct advantages and limitations. Therapeutic approaches are discussed, ranging from conservative management with pharmacotherapy and bile acid dissolution agents to interventional procedures like extracorporeal shock wave lithotripsy (ESWL) and percutaneous cholecystostomy. Surgical management, particularly laparoscopic cholecystectomy, remains the gold standard for definitive treatment. Additionally, advancements in endoscopic techniques, including endoscopic sphincterotomy (EST) and cholangioscopy, are highlighted. This review synthesizes current research findings and clinical guidelines, aiming to enhance the understanding and management of gallstone-related complications among healthcare professionals, thereby improving patient outcomes and reducing the burden of this common ailment.

An unusual case of gallstone ileus 35 years post-cholecystectomy masked by an incisional hernia

Gallstone ileus is an uncommon cause of mechanical bowel obstruction in patients with cholecystitis and gallstones who develop a fistula over time. In the post-cholecystectomy patient, the presence of gallstone ileus is extremely rare; these patients have different pathophysiological pathways, such as a spilled gallstone that subsequently erodes into the bowel, subtotal cholecystectomies, and diverticulae that can hold a gallstone for hidden several years. In these patients, the clinical presentations are unique because of their rarity and because the gallbladder had been previously removed. A high index of suspicion by the medical team is needed for diagnosis. We present the case of an 85-year-old male who had a history of cholecystectomy 35 years ago. He presented to the emergency department with intestinal obstruction. Since he had a hernia, it was thought to be the cause of the obstruction; however, during surgery, we were surprised to find a gallstone ileus. After surgery, he fully recovered.

Upper gastrointestinal bleeding and Rigler triad

Gallstone ileus is a rare complication of cholelithiasis, characterized by mechanical bowel obstruction due to a biliary calculus originating from a bilioenteric fistula. The Rigler triad, consisting of aerobilia, ectopic gallstone, and intestinal obstruction, is rarely observed in its complete form. We present the case of a 92-year-old male with a history of acute lithiasic cholecystitis who presented to the Emergency department with acute epigastric pain. Initial evaluation revealed gallbladder dilatation, gallstones, and gallbladder wall thickening suggestive of acute cholecystitis. During hospitalization, the patient experienced an episode of hematemesis, leading to the diagnosis of a cholecystoduodenal fistula and a large blood clot in the duodenal bulb. Further imaging showed an ectopic gallstone causing small bowel obstruction. The patient underwent urgent surgery for stone extraction, followed by endoscopic intervention for the bleeding vessel identified at a subsequent gastroscopy. Unfortunately, the patient had a poor postoperative course and passed away seven days later. This case report highlights the exceptional occurrence of both the Rigler triad and upper gastrointestinal bleeding in a patient with gallstone ileus. Surgical intervention is crucial for the initial resolution of intestinal obstruction, followed by cholecystectomy and repair of the bilioenteric fistula. Awareness of these rare presentations is important for timely diagnosis and appropriate management of this uncommon complication of cholelithiasis.

Management of complex acute biliary disease for the general surgeon: A narrative review

Acute gallbladder diseases are a common surgical emergency faced by General Surgeons that can sometimes be quite challenging. These complex biliary diseases require multifaceted and expeditious care, optimized based on hospital facility and operating room (OR) resources and the expertise of the surgical team. Effective management of biliary emergencies requires two foundational principles: achieving source control while mitigating the risk of injury to the biliary tree and its blood supply. This review article highlights salient literature on seven complex biliary diseases: acute cholecystitis, cholangitis, Mirizzi syndrome, gallstone ileus with cholecystoenteric fistula, gallstone pancreatitis, gall bladder cancer, and post-cholecystectomy bile leak.

Gallstone ileus: An unusual complication of cholelithiasis in a 42-year-old female with no comorbidities

INTRODUCTION AND IMPORTANCE

Gallstone ileus is a rare condition, accounting for 0.5 % of mechanical small bowel obstructions. It is a misnomer for mechanical intestinal obstruction caused by one or more gallstones impacted within the gastrointestinal tract lumen, which occurs mostly in the elderly and female population. Treated usually by operative enterolithotomy. Preoperative diagnosis is challenging, but CT, which is investigation of choice, and magnetic resonance imaging (MRI) have made it easier to diagnose.

CASE PRESENTATION

A 42-year-old female presented to the emergency department with epigastric abdominal pain for 1 week, preceded by 2 months of RUQ pain. CT scan with contrast showed a classical finding of small bowel obstruction and ectopic gallstone. An emergency exploratory laparotomy, enterolithotomy, and cholecystectomy with fistula repair were performed in one surgical stage.

CLINICAL DISCUSSION

Laparoscopic enterolithotomy alone is the most preferred method due to its low incidence of complications but one-stage or two-stage surgeries are also options, but the choice between surgical modalities depends on the patient's status.

CONCLUSION

Gallstone ileus mostly affects older female patients who have a history of gallbladder disease and often have a poor prognosis that becomes worse with age and comorbidities. However, this was a young female patient with no comorbidities, which may affect the prognosis compared to those who are at risk for gallstone ileus.

Gallstone ileus 30 years after cholecystectomy and hepaticojejunostomy

Gallstone ileus occurs when the small or large intestine is obstructed by a gallstone and is a rare occurrence in a post-cholecystectomy patient. Non-specific clinical symptoms and inconsistent imaging results often lead to a delay in diagnosis. Complex anatomy, such as a Roux-en-Y biliary-enteric anastomosis, can increase the risk of stone formation and further confound a potential case of gallstone ileus. Here, we present a rare case of gallstone ileus at the anastomosis site of a Roux-en-Y hepaticojejunostomy done 30 years prior for a common bile duct injury during a cholecystectomy. The possibility of negative CT findings, pattern of presentation on imaging as intussusception, and potential pathomechanism of gallstone formation in post-cholecystectomy patients are discussed. Through this case and review of similar cases, we emphasise the need for further study of post-cholecystectomy gallstone ileus and the importance of clinical suspicion during diagnosis.

Medical Misnomers Are Murky: Time to Memorialize and Rename

Misnomers have dogged medical practice seemingly since its inception. They may arise out of initial misunderstanding of the underlying disease process, a fanciful personification of the disease itself, or simple confusion encountered early in the disease's discovery. Misnomers are not harmless. By increasing unneeded complexity, they add to challenges in medical education without increasing understanding. Practicing clinicians may experience difficulties in communicating with patients. For example, a diagnosis of "ringworm" may be made but the patient may not understand why an antiparasitic is not being prescribed, requiring an explanation that it is a dermatophytic condition and not a parasitic one. Although no randomized controlled trial can be conducted, misnomers can arguably create unconscious bias in clinician minds about the underlying pathophysiology of different conditions. We aim to end the cycle of misinformation by pointing out some common misnomers and encouraging alternate names that are more accurate, either novel or already in use. We invite the reader to send us more examples from their field.

Double Trouble: A Case of Gallstone Ileus as a Result of Multiple Obstructive Gallstones

Gallstone ileus is a rare condition. It accounts for approximately 1% of small bowel obstruction and is more prevalent in the elderly population. It is usually present in relatively comorbid patients posing further operative challenges. The following report investigates the management of two large gallstones resulting in two different points of obstruction. Is double trouble doubly hard to manage?

Metabolic dysfunction-associated gallstone disease: expecting more from critical care manifestations

About 20% of adults worldwide have gallstones which are solid conglomerates in the biliary tree made of cholesterol monohydrate crystals, mucin, calcium bilirubinate, and protein aggregates. About 20% of gallstone patients will definitively develop gallstone disease, a condition which consists of gallstone-related symptoms and/or complications requiring medical therapy, endoscopic procedures, and/or cholecystectomy. Gallstones represent one of the most prevalent digestive disorders in Western countries and patients with gallstone disease are one of the largest categories admitted to European hospitals. About 80% of gallstones in Western countries are made of cholesterol due to disturbed cholesterol homeostasis which involves the liver, the gallbladder and the intestine on a genetic background. The incidence of cholesterol gallstones is dramatically increasing in parallel with the global epidemic of insulin resistance, type 2 diabetes, expansion of visceral adiposity, obesity, and metabolic syndrome. In this context, gallstones can be largely considered a metabolic dysfunction-associated gallstone disease, a condition prone to specific and systemic preventive measures. In this review we discuss the key pathogenic and clinical aspects of gallstones, as the main clinical consequences of metabolic dysfunction-associated disease.

Comparing outcomes of operative management of intestinal obstruction due to gallstone ileus using NSQIP database

Introduction

Gallstone ileus is an uncommon etiology of intestinal obstruction, although many cases require surgical repair. There is no consensus regarding the necessity of concomitant cholecystectomy. (CCY) at the time of index surgery. This study aimed to evaluate the outcomes of gallstone ileus in patients with and without CCY.

Methods

Using the ACS NSQIP database from 2005 to 2019, we included patients who underwent surgical management of gallstone ileus (enterolithotomy) with or without CCY. The primary outcomes of interest were surgical site infection (SSI) and 30-day mortality. Additional outcomes of interest included readmissions related to the procedure, length of hospital stay (LOS), return to the operating room, and sepsis. Demographics were evaluated using univariate analysis, whereas outcomes of interest were analyzed using multivariate logistic regression.

Results

A total of 825 cases of gallstone ileus were identified among 118 patients who underwent cholecystectomy. Patient characteristics were similar between the groups. No concomitant cholecystectomy was associated with a longer hospital stay (8 days vs. five days, p<0.01) and tended to be more likely to return to the operating room (45 cases vs. 4 cases, p = 0.08), but this was not statistically significant. No concomitant CCY was associated with increased SSI rates, readmissions related to the procedure, 30-day mortality, or sepsis.

Conclusion

Surgical management of gallstone ileus with or without CCY has similar short-term postoperative outcomes.

Gallstone Enteropathy: An Unusual Cause of Bowel Obstruction

Gallstones causing bowel obstruction, known as gallstone ileus, are rare and account for less than 0.5% of small bowel obstruction cases. Additionally, it is a rare complication affecting only 0.3% of patients who have gallstones. Fistula formation between the biliary system, most commonly between the gallbladder and duodenum because of their proximity, facilitates the migration of gallstones into the enteric system with subsequent impaction in the small intestine, usually in the distal ileum close to the ileocecal valve, promoting the development of mechanical small bowel obstruction. Computerized tomography of the abdomen and pelvis is a confirmatory and widely used imaging study when there are two signs of Rigler's triad, which includes pneumobilia, evidence of small bowel obstruction and the presence of radiopaque stones. We report a case of a 75-year-old Caucasian man who presented with abdominal distention with signs of severe dehydration secondary to intractable nausea and vomiting complicated with severe acute kidney injury and was found to have a 4.7-centimeter gallstone-induced small intestinal obstruction.

Colonic Perforation Secondary to Gallstone Impaction in the Sigmoid Colon

Introduction

Gallstone sigmoid ileus is a very rare manifestation of large bowel obstruction. Mainly, three conditions predispose the manifestation of the entity; in particular, an episode of cholecystitis causing cholecysto-colonic fistula; a large gallstone; and narrowing of the sigmoid colon secondary to diverticular disease or malignancy. Case Report. An 82-year-old man presented to the emergency department with a one-week history of severe constipation, tachypnoea, tachycardia, hypotension, and high lactate. Physical examination demonstrated cyanosed upper and lower extremities and palpation of the abdomen revealed signs of peritonism, abdominal distention, and guarding. Computerized tomography scan demonstrated perforation of the hollow viscus organ secondary to impaction of the large gallstone in the sigmoid colon. Laparotomy revealed sigmoid perforation and widespread feculent peritonitis. The patient underwent Hartmann's procedure. After the intervention gave concerns regarding the patient's haemodynamic stability, he was transferred to the intensive care unit. The patient passed away on the third postoperative day due to complications secondary to haemodynamic instability.

Conclusions

Patients with early diagnosed uncomplicated sigmoid gallstone ileus can be managed with endoscopic mechanical lithotripsy. In case of failure, open or laparoscopic enterolithotomy can be applied. However, when patients present with complications, surgery should not be delayed. In our case, Hartmann's procedure was an absolute indication due to sigmoid perforation and widespread feculent peritonitis.

Two Sites of Obstruction with Gallstones: A Case Report of Bouveret Syndrome with a Concurrent Biliary Ileus

Bouveret syndrome is a gastric outlet obstruction, and biliary ileus is an obstruction of the small bowel, and both are caused by a gallstone that escaped the gallbladder through a bilio-enteric fistula. The concurrent occurrence of obstruction at both sites is encountered very rarely, and only two such cases associated with Bouveret syndrome were reported before. We now present a case involving a 78-year-old female with simultaneous obstruction at both the duodenum and jejunum. The literature is reviewed to evaluate the incidence of such a situation and to discuss the management of the case.

Gallstone Ileus: Clinical Presentation and Radiological Diagnosis

The term "gallstone ileus" refers to intestinal obstruction brought on by a gallstone lodged within its lumen. The gallstone travels through a fistula that develops because of the constant pressure it exerts on the gall bladder. The symptoms are vague and confounding which can commonly lead to delay in diagnosis. The preferred imaging technique is a computed tomography scan. The diagnosis is confirmed by the identification of Rigler's Triad on a CT scan, which includes a small intestinal obstruction, pneumobilia, and an ectopic stone in the intestine. The condition is associated with several complications and needs to be treated with emergency surgery. This case demonstrates how a patient could have non-specific symptoms and how early detection by imaging was crucial to the patient's treatment.

Non-operative management of gallstone sigmoid ileus in a patient with a prostatic cancer

Gallstone ileus is an uncommon complication of calculus cholecystitis through the formation of a biliary enteric fistula. The risk of mechanical obstruction caused by gallstones is increased with its size, in addition to chronic constipation, neoplasm and diverticulitis, to name a few. Here, we present a case of an 89-year-old male patient who presented with signs of bowel obstruction, which was found to be a gallstone impacted in the sigmoid colon. Considering the patient's stable condition and his comorbidities, a conservative approach was opted including IV fluids, fleet enema and bowel rest. Colonoscopy was performed and confirmed the passage of the stone. With no consensus regarding the management, the literature emphasizes a tailored approach to each case considering all possible operative and non-operative approaches. Some reports show promising results with non operative management. Gallstone ileus remains a challenging case, and further studies for the best treatment modalities are needed.

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.

Gallstone ileus: A case report and review of the literature

INTRODUCTION AND IMPORTANCE

Gallstone ileus (GI) is defined as the occlusion of the intestinal lumen due to the impaction of one or more gallstones. The optimal management of GI is not consensual. We report a rare case of GI with a successful surgical treatment for a 65 year-old-female.

CASE PRESENTATION

A 65 year-old-woman, presented with biliary colic pain and vomiting for three days. On examination, she had a distended tympanic abdomen. A computed tomography scan revealed signs of small bowel obstruction due to a jejunal gallstone. She had pneumobilia due to a cholecysto-duodenal fistula. We performed a midline laparotomy. We found a dilated and ischemic jejunum with false membranes regarding the migrated gallstone. We performed a jejunal resection with primary anastomosis. We performed cholecystectomy and closed the cholecysto-duodenal fistula at the same operative time. The postoperative course was uneventful.

CLINICAL DISCUSSION

We reported successful surgical treatment for GI. It was a one-step procedure. GI is a rare situation. Due to their restricted lumen, the terminal ileum and the ileocaecal valve are where GI occurs most commonly. GI appears usually in elderly patients with comorbidities. The clinical presentation is not specific. CT scan evokes the diagnosis with high specificity. The surgical management of GI is not consensual. In our case, we performed bowel resection due to the presence of an ischemic intestine.

CONCLUSION

GI is a rare situation. It appears usually in elderly patients with comorbidities. The clinical presentation is not specific. The surgical management of GI is not consensual.

Gallstone Ileus With Cholecystoenteric Fistula in an Elderly Female: A Case Report

Mechanical small-bowel obstruction can occur due to various reasons, including the impaction of a gallstone in the ileum after it has passed through a cholecystoenteric fistula. Gallstone ileus is an infrequent yet significant cause of this condition. This case report documents an instance of gallstone ileus, which accounts for less than 1% of patients with mechanical small bowel obstruction. We report a 75-year-old female patient who presented with colicky pain in both upper quadrants, hyporexia, and constipation that worsened during a period of nine days, which subsequently was accompanied by nausea and vomiting of bilious appearance in the next three days. Abdominal CT reported a dilated common bile duct (1.7 cm) with multiple stones inside measuring between 5 and 8 mm associated with pneumobilia of intrahepatic bile ducts and dilatation of small intestinal loops produced by a high-density image of approximately 2.5 cm. Laparoscopic exploration showed an obstructive mass measuring 15 cm from the ileocecal valve corresponding to a 2.54 x 2.35 cm gallstone, which was removed and enterorrhaphy was performed. The sine qua non condition for gallstone ileus to occur is the presence of a fistula between the gallbladder and the gastrointestinal tract. The treatment is mainly surgical and should be aimed primarily at the intestinal obstruction and secondarily at the cholecystoenteric fistula. This condition tends to have a high rate of complications and consequently long hospital stays. Making a timely diagnosis provides us with the tools for a surgical approach aimed at intestinal obstruction and subsequently in the management of the biliary fistula.

Colonic gallstone ileus treated by a transanal ileus tube followed by spontaneous gallstone dislodgement: A case report

A 71‐year‐old obese woman was referred to our hospital with lower left abdominal pain. Computed tomography showed a 46 mm elliptic calcification lodged in the sigmoid‐descending colon junction (SDJ), which had been detected 5 years prior but was not within the gall bladder at presentation. Therefore, we diagnosed colonic gallstone ileus with obstructive colitis caused by a gallstone. Colonoscopy revealed a smooth gallstone impacted at the sigmoid‐descending colon junction, which was not fixed and could be pushed proximally with the endoscope. Dislodgement of the stone was unsuccessful with both a large polypectomy snare and a retrieval basket. Considering the high risk of surgery, we chose a non‐surgical treatment strategy for obstructive colitis. Accordingly, a transanal ileus tube was placed to drain the proximal portion of the gallstone. The drainage of the colon by the ileus tube was satisfactory; the proximal colon was decompressed, ameliorating the obstructive colitis. Five days after tube placement, a colonoscopy revealed spontaneous passage of the gallstone into the rectum where it was finally removed. Cholecystocolonic fistula formation was confirmed by magnetic resonance imaging. We decided to surgically close the cholecystocolonic fistula to prevent future retrograde biliary infections. The surgery used a surgical stapler and was successful, with an uneventful postoperative course. Since radical surgical treatment of colonic gallstones and cholecystoenteric fistulas has a risk of postoperative morbidity and mortality, this case illustrates the importance of thoroughly considering nonsurgical interventions and surgeries for the safe treatment of colonic gallstone ileus.

A Rare Case of Cholecystoduodenal and Cholecystocolic Fistula with Gallstone Ileus

Cholecystoduodenal and cholecystocolic fistula (CCF) is a rare condition, occurring in patients with cholelithiasis. Multiple complex fistulas are even rare. This is a case study done to detail such a rare case, very few such cases have been reported in the past studies, with cholecystoduodenal and CCF with gallstone ileus. We present the case of an 80-year-old, female diagnosed with intestinal obstruction. Intraoperatively, the gallbladder (GB) fundus forms a CCF and the body of the GB with the first part of the duodenum forms cholecystoduodenal fistula. Gallstone ileus found impacted in jejunum 35 cm distal to DJ junction. Resection of fistula tracts with primary repair of the transverse colon was done with Graham's patch repair of duodenum and fundus first cholecystectomy. Cholecysto-duodeno-colic fistulas complicated with gallstone ileus are very rare. In the case of gallstone ileus, the surgical treatment is an emergency and the only therapeutic option.

A Case of Bouveret's Syndrome Treated With Holmium:Yttrium-Aluminum-Garnet Laser

Bouveret's syndrome is a rare form of gallstone ileus described as a gastric outlet obstruction from a gallstone that travels from the gallbladder to the bowel through a bilioenteric fistula. Despite its rarity, the mortality rate of this condition is high. Endoscopic treatment is preferred over surgery due to the association with lower mortality rate. To date, there are limited data about the application of holmium:yttrium-aluminum-garnet (YAG) laser lithotripsy for fragmentation of gallstones in Bouveret's syndrome. We present the case of a 74-year-old man with multiple cardiac comorbidities who presented with periumbilical pain, decreased appetite, and vomiting. The patient had previously been admitted three months prior with acute cholecystitis, and a cholecystostomy tube was placed. He had leukocytosis and purulent discharge in his cholecystostomy bag. Computed tomography (CT) scan of the abdomen and pelvis showed a change in the position of a previously seen large gallstone from the neck of the gallbladder on the last admission, to the lumen of the duodenal bulb on this admission. This indicated the development of a cholecystoduodenal fistula, with the stone passing through this fistula into the duodenal bulb, causing the complete obstruction. Endoscopic treatment was recommended by the surgery team due to cardiac comorbidities and the significant friability of the tissue requiring laparotomy. Initial endoscopic evaluation showed complete obstruction of the duodenal bulb by a large smooth stone, not allowing passage of a guidewire beyond the stone. Therefore, holmium:YAG laser lithotripsy was used. After two sessions of laser therapy, four days apart, each breaking a pigmented and calcified stone, it eventually passed through the small bowel into the colon, relieving the obstruction. The patient had a favorable outcome and did not require surgery. This case report shows that holmium:YAG laser lithotripsy is capable of delivering favorable outcomes, as seen in a patient with a heavily calcified and pigmented stone, older age, and multiple comorbidities. Holmium:YAG laser could be considered for use with endoscopic equipment for future management of this condition, especially in patients who have medical comorbidities and heavily calcified gallstones.

Gallstone Ileus Post-cholecystectomy: A Case Review

Gallstone ileus is an unusual cause of small bowel obstruction, in general, let alone after cholecystectomy. It occurs in patients with chronic calculous cholecystitis and gallstones who develop a cholecystoduodenal fistula over time. The diagnosis is made based on clinical presentation and examination findings and is confirmed with the use of radiological modalities, such as computed tomography (CT) scan, which has been proven to be the most sensitive investigation in diagnosis. Here, we present a case of gallstone ileus that occurred 25 years after laparoscopic cholecystectomy. CT scan on admission showed adhesional small bowel obstruction given the patient's previous abdominal surgery. The patient was managed conservatively as per guidelines for the management of adhesional small bowel obstruction for 72 hours. Obstructive symptoms did not resolve despite all conservative measures, and a gastrografin challenge showed no contrast reaching the colon. Hence, the patient underwent an exploratory laparotomy to manage his ongoing bowel obstruction. Laparotomy revealed gallstone ileus as the cause of obstruction. This case highlights the importance of considering gallstone ileus in the differential diagnosis for patients who present to the emergency department with small bowel obstruction even years after cholecystectomy. Post-cholecystectomy gallstone ileus is very rare with very few cases reported in the literature. This condition poses diagnostic challenges both because of its rarity and because the gallbladder had been previously removed. A high index of suspicion by the surgeon is needed for diagnosis.

The Role of Magnetic Resonance Imaging in a Difficult Case of Gallstone Ileus

Gallstone ileus is an uncommon condition that is difficult to diagnose clinically. Although several cases have been reported in the literature, radiolucent gallstones in the setting of gallstone ileus are an exceedingly rare occurrence, and we have not identified any authors who used magnetic resonance imaging (MRI) for the acute diagnosis of this condition. While an MRI is the gold standard for visualizing gallstones, inpatient MRIs are difficult to obtain, even in resource-rich settings. However, if given a high index of suspicion for gallstone ileus, it is pertinent to advocate for an inpatient MRI despite a resolution of patients' symptoms due to the nature of the disease symptomology.

Developments in the Diagnosis and Management of Cholecystoenteric Fistula

Background: Cholecystoenteric fistula (CEF) is a rare complication of cholelithiasis. CEF refers to one or more pathological perforations between the gallbladder and the adjacent gastrointestinal tract, first described by Bartholin in 1645. The aim of this review is to examine the etiology, symptoms, diagnosis, and treatment of CEF.Methods: A literature search was conducted according to a set of criteria in PubMed for historical and current peer-reviewed studies regarding CEF.Results: Clinical manifestations of CEF are always latent. Despite modern imaging studies and diagnostic methods, it is still very difficult to definitively diagnose CEF preoperatively. Instead, CEF is often accidentally discovered in the perioperative period or via intraoperative exploration.Conclusions: Without appropriate preoperative preparation, gastrointestinal injury and intraoperative bleeding often occur. CEF often goes unreported, and its diagnosis and treatment are still controversial. Early diagnosis of CEF is essential for effective treatment and improved outcome.

Surgical treatment of hepatic xanthogranuloma arising from a giant hepatic cyst causing gastrointestinal obstruction: a case report

Hepatic cysts are benign liver lesions and are often asymptomatic. Large hepatic cysts may cause jaundice and portal hypertension; however, they rarely cause gastrointestinal obstruction. Symptomatic cysts require treatment, and when malignancy is suspected, cyst puncture for pathological examination of the fluid may pose a risk of dissemination. Herein, we describe a case of xanthogranuloma arising from a large hepatic cyst that was causing duodenal obstruction. Thus, cyst puncture was performed for emergency decompression. Cytological examination of the puncture fluid revealed no malignant findings. Hence, laparoscopic deroofing was performed to treat the hepatic cyst. As the cyst and duodenal wall were firmly adherent, the cyst wall was left behind without dissection from the duodenum. A two-stage approach of cyst puncture followed by surgery may be an option for patients requiring urgent treatment for potentially malignant hepatic cysts.

Case series of gallstone ileus with one- or two-stage surgery

Gallstone ileus is an uncommon cause of intestinal obstruction. It may present with typical symptoms of intestinal obstruction with or without biliary sepsis. Its management strategies vary depending on the patient and operative factors. Enterotomy and stone removal alone versus synchronous cholecystectomy and fistula disconnection at the same stage, often pose a debate among surgeons. The decision for operative strategies largely depends on the surgeon's experience, patient's physiology, and operative difficulties. As literature on gall stone ileus remains insufficient at a regional level, we report four cases of gallstone ileus managed with different approaches. Three patients were managed in a staged-manner, whereas one patient received a definitive procedure performed at index surgery. Clinical challenges and associated operative strategies are discussed. Findings of the current study were compared to those of the literature. The need for a definitive fistula disconnection and repair or cholecystectomy following stone removal in these patients was subsequently discussed.

Gallstone ileus in a middle-aged male with an atypical history: a case report

Currently, gallstone ileus is an unusual complication of cholelithiasis (0.3–3.0 %) and a rare cause of mechanical bowel obstruction (0.1–4.0 %). The rarity of the condition makes it impossible to plan the large prospective randomized clinical trials, so the analysis of case reports is significant for decision making in the management of gallstone ileus. We report a case of gallstone ileus in a middle-aged male who had a history of surgery for duodenal ulcer perforation in past. A combination of peptic ulcer disease and cholelithiasis is based on a reduced gastrointestinal hormones secretion. Clinical specialists need to consider information about the greater frequency and asymptomatic clinical course of gallstone disease against a background of duodenal ulcer. Duodenal ulcer scar and bulbar deformity may promote to the cholecystoduodenal fistula formation. In the presence of an acute bowel obstruction symptoms and the absence of gallbladder instrumental examination results, it is possible to recommend the prior gastroduodenoscopy for the pre-operative pneumobilia detection. The optimal surgical approaches for acute gallstone ileus are still controversial.

Indocyanine green fluorescence: A surgeon's tool for the surgical approach of gallstone ileus

Fluorescence cholangiography has been shown to improve biliary anatomy identification. A case of 60-year-old man with intestinal obstruction is reported, an entero-biliary fistula is suspected, and intravenous application of indocyanine green is decided, despite the great inflammatory process and fibrotic tissues found during the procedure, safe open cholecystectomy was achieved.

Mirizzi Syndrome With Bouveret Syndrome: A Rare Amalgam

Mirizzi and Bouveret syndromes are uncommon but important complications of calculous cholecystitis. Mirizzi syndrome commonly presents with jaundice due to extrinsic compression on the common bile duct by an impacted stone at the gall bladder infundibulum, whereas Bouveret syndrome presents with gastric outlet obstruction due to a large stone in the duodenum. Our case is a 65-year-old lady who presented with pain in the right upper abdomen associated with nausea and vomiting. Contrast-enhanced computed tomography and MRI of the abdomen were suggestive of calculus in the infundibulum of the gall bladder with compression over the common bile duct and a large stone in the first part of the duodenum. Upper gastrointestinal endoscopy confirmed the findings but could not retrieve the stone. Cholecystectomy with the retrieval of calculus from the infundibulum and duodenum was performed with the closure of the fistulous opening. The patient did well in the post-operative period and is doing well after nine months of follow-up. Chronic calculus cholecystitis can present in varied forms, and one should be aware of such rare complications and their management.

Gallstone ileus: Unusual complication of cholelithiasis: A case report

Introduction and importance

Gallstone ileus is a rare cause of intestinal obstruction with a high morbidity and mortality rate, which is often linked to delayed or misdiagnosed intestinal obstruction. Gallstone ileus requires a high index of suspicion to diagnose.

Case presentation

This report describes a 55-year-old male who presented the case of gallstone ileus with four years history of gallstone disease, emergency explorative laparotomy was done, enterotomy and stone extraction from the small bowel, the post-operative patient was uneventful and was discharged after full enteral tolerance.

Clinical discussion

CT scanning has become increasingly important as a diagnostic tool, with a sensitivity of 93% and its use has increased in recent years, In the case of patients with gallstone ileus, simple enterolithotomy is both safe and effective.

Summarize the surgical techniques performed to management gallstone ileus.

A Path Less Travelled: A Case Report of an Unusual Trip of a Gall Stone

Gall stone ileus is one of the rare complications of patients with cholelithiasis and usually affects elderly females. The usual sites for the stone to get impacted are the distal ileum and ileocaecal valve. Computed tomography (CT) remains diagnostic and surgery is the treatment of choice. A 60-year-old diabetic female, who was diagnosed with gall stone-induced pancreatitis one month ago, presented to the surgical emergency department with complaints of right upper abdominal pain with recurrent vomiting and constipation of five days duration. The patient was managed conservatively. A provisional diagnosis of subacute intestinal obstruction was kept and a barium meal follow-through (BMFT) was requested. However, BMFT was inconclusive. After two weeks, she presented again to the emergency department with clinical features of subacute intestinal obstruction. The patient was planned for exploratory laparotomy in view of recurrent episodes of obstruction and the presence of peritonism. Intraoperatively, we encountered a cholecystogastric fistula with a gall stone of size approximately 6.5x4 cm impacted at approximately 60 cm from the ileocaecal junction and dilated proximal small bowel loops. The surgical procedure comprised enterolithotomy and cholecystectomy along with repair of cholecystogastric fistula done. The patient had an uneventful postoperative course. Gall stone ileus is a rare cause of small bowel obstruction. Gall stone ileus presenting with a recent history of pancreatitis further makes the suspicion very unlikely.

An unusual case of subacute small bowel obstruction - Gallstone ileus

Introduction and importance

Gallstone ileus is caused by an impaction of one or more gallstones within the gastrointestinal tract, leading to mechanical intestinal obstruction. It is a rare complication of cholelithiasis leading to the formation of a cholecystoenteric fistula and is associated with high mortality rates. We report a case of atypical subacute small bowel obstruction due to gallstone ileus.

Presentation of case

An 82-year-old man, with previously diagnosed cholelithiasis, presented with abdominal pain and vomiting for nine days. The contracted gallbladder with distended bowel loops was visualized on abdominal ultrasound. Computed tomography of the abdomen and pelvis revealed dilated loops of the small intestine with a gallstone in the proximal ileum, causing intestinal obstruction with pneumobilia, suggesting gallstone ileus with cholecystoduodenal fistula. The patient underwent an emergency laparotomy and enterolithotomy to remove the impacting gallstone. The cholecystoduodenal fistula was left undisturbed due to the significant risk of duodenal injury. The patient had an uneventful postoperative recovery.

Conclusion

Gallstone ileus almost always requires surgical management. However, performing an interval biliary surgery is based on the clinical judgment of the surgeon. In our case, the patient's clinical status determined the treatment in which an enterotomy with stone extraction alone was largely sufficient, and has supported the literature. Gallstone ileus is an important differential diagnosis in elderly patients with gallstone disease, untreated or undiagnosed, presenting with features of small bowel obstruction.

•

Gallstone ileus is a rare cause of small bowel obstruction, commonly in the elderly.

•

Cholelithiasis, untreated or undiagnosed, may result in a cholecystoduodenal fistula and gallstone ileus.

•

CT scan is the preferred imaging modality and characteristic radiological findings aid in early diagnosis.

•

An enterotomy with stone extraction is sufficient in comorbid patients without intruding on the cholecystoduodenal fistula.

Clinical outcome of gallstone ileus; a single-centre experience of case series and review of the literature

BACKGROUND

Gallstone ileus (GI) is a rare entity which is seen in 0.5% of patients with cholelithiasis. In this study, we aimed to share our clinical approach to GI, to present our long-term results and to draw clinicians' attention to this rare entity.

MATERIALS AND METHODS

This study included 11 patients with GI whose medical records were evaluated retrospectively.

RESULTS

Majority of the 11 patients were female (63.7%, n:7) and the mean age was 71.9 ± 14.10 (range: 50-91). Most common presenting complaints were vomiting (n: 9) and abdominal pain (n: 9). The mean interval from the onset of symptoms to the hospital admission was 3.8 ± 0.75 (range 3-5) days. Rigler triad in abdominal computed tomography (CT) was detected in all cases. Enterolithotomy, one-step procedure and conservative treatment were performed in five (45.4%), four (36.3%) and two (18.1%) patients, respectively. Enterolithotomy group was found to have higher risk according to American Society of Anesthesiologists (ASA) classification, shorter operation time and less intraoperative blood loss.

CONCLUSION

Although enterolithotomy is the first choice for patients with GI, one-step procedure should be kept in mind as a more advantageous technique in low-risk patients.

Gallstone Ileus in Octogenarians: Is Cholecystectomy Really Needed?

Gallstone ileus is an uncommon complication of cholelithiasis and occurs when a gallstone migrates through a cholecystoenteric fistula and impacts within the gastrointestinal tract. Surgical intervention remains the treatment of choice, which consists of a full-thickness incision of the visceral wall and removal of the impacted gallstone. In this paper we present the treatment approach of 6 cases of gallstone ileus in octogenarians. In our cohort, intestinal obstruction was resolved through an enterotomy or gastrotomy and lithotomy/stone extraction in every patient. No cholecystectomies were undertaken. Despite the fact that gallstone ileus is diagnosed in small percent of patients suffering from gallstone disease, it accounts for a large proportion of intestine obstruction in patients older than 65 years old. Since accurate diagnosis and timely intervention are vital, providers should be familiar with the diagnostic approach and the treatment of this clinical entity.

Colonic Gallstone Ileus: Treatment Challenges

Intestinal obstruction at the level of the colon is rarely caused by a gallstone. Colonic gallstone is more frequently observed in elderly patients and is associated with high mortality due to treatment challenges. Management with less invasive approaches, including mechanical lithotripsy and endoscopy has been evolving. However, the outcomes are variable, and surgery remains the main cornerstone of treatment. We present a case of an 89-year-old male with gallstone ileus at the level of the sigmoid colon in whom treatment with endoscopy was not successful. We performed an extensive review of the literature to understand the most common presentation, diagnostic modalities, and treatment approach of the sporadic reported cases of colonic gallstone ileus.

Totally laparoscopic resolution of gallstone ileus: A case report

INTRODUCTION

Gallstone ileus is an uncommon complication of long-term cholelithiasis. Emergent operations for gallstone ileus are associated with high postoperative morbidity. When feasible, the minimally invasive approach might help to improve the postoperative outcomes.

PRESENTATION OF CASE

A 63-year-old female was admitted for abdominal pain and vomiting. Computed tomography (CT) scan showed a cholecystoduodenal fistula and a 5 × 3 cm gallstone in the jejunum causing obstruction. An emergent laparoscopy was performed, and a gallstone was found inside the jejunum 40 cm distal to the ligament of Treitz. The 5 cm gallstone was extracted through an antimesenteric enterotomy. The jejunum was then closed transversally using interrupted sutures. The postoperative course was uneventful, and the patient was discharged on postoperative day 3.

DISCUSSION

Surgery is the mainstream treatment for gallstone ileus. Multiple operations and surgical approaches have been described: enterolithotomy (EL), one-stage surgery (EL, cholecystectomy, and fistula closure), bowel resection, and two-stage surgery (EL and delayed cholecystectomy with fistula closure). The choice of the procedure depends on the patient's characteristics, comorbidities, and experience of the surgical team.

CONCLUSION

In the emergency setting, a simple enterolithotomy with primary closure seems to be the optimal approach to solve the intestinal obstruction with low postoperative morbidity. The laparoscopic approach to gallstone ileus results in additional benefits for patients' recovery.
