A single centre case series of gallstone sigmoid ileus management

Like a Rolling (Gall)Stone: Optimal Treatment of Gallstone Obstruction of the Sigmoid Colon

BACKGROUND

Sigmoid gallstone ileus is a rare complication of cholelithiasis, accounting for 1-4% of all cases of large-bowel obstruction. This is a highly morbid, and often fatal, condition due to its challenging diagnosis and late presentation.

CASE PRESENTATION

We report a case of a 90-year-old woman admitted to Emergency Department with abdominal pain and large-bowel obstruction due to a 6 cm gallstone lodged in a diverticulum of the proximal sigmoid colon as a consequence of a cholecysto-colonic fistula. Colonoscopy was deferred due to gallstone size carrying a high possibility of failure. The patient underwent urgent laparotomy with gallstone removal via colotomy. The cholecystocolonic fistula was left untreated. The post-operative course was uneventful; the patient was discharged on 6th post-operative day.

CONCLUSION

A multidisciplinary discussion between endoscopists and surgeons is often needed to choose the best therapeutic option, especially in high-risk patients.

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.

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.

Successful Treatment of Cholecysto-Antral Fistula: A Case Report

Cholecysto-antral fistula and gallstone ileus are rare complications of a common disease, gallbladder stone (GBS). This fistula is developed as a prolonged complication of cholelithiasis in which the gallbladder adheres to the adjacent antrum, and a stone erodes through the wall. Among the variety of cholecystoenteric fistulae, the cholecystoduodenal fistula occurs more commonly than the cholesysto-antral fistula. In this scientific study, we present a 98-year-old male patient who came to ER with a complaint of abdominal pain, vomiting, and constipation for five days. He was vitally stable and had normal laboratory results. The plain abdominal X-ray showed dilated loops with excessive gases. His computed tomography (CT) abdomen with contrast showed small bowel obstruction secondary to an impacted gallstone at the distal jejunum, fistulous communication between the gall bladder and the antrum, and pneumobilia. Our management included endoscopic retrieval of a single gallstone from the second part of the duodenum followed by open surgical enterolithotomy, partial cholecystectomy, and closing of the fistula. Despite our case sharing many aspects with the available literature, our case, to our knowledge, is the first case of ileus gallstone occurring in a 98-year-old patient. Cholecysto-antral fistula has not been widely published in the literature. The offending gallstone presented along with the radiological Mercedes Benz sign which does not present in all cases of GBS. Typically, the obstructing GBS stops at the terminal ileum, but in our case, it was dislodged in the distal jejunum with no previous biliary symptoms. Finally, we were able to remove another single GBS from the second part of the duodenum during the preoperative upper endoscopy. The clinical diagnosis may be missed due to the vague presentation of symptoms; hence imaging, especially of the CT abdomen is crucial in establishing the diagnosis, moreover, performing an upper endoscopy could have diagnostic and therapeutic benefits. In cases like this, the main surgical intervention should be to address the bowel obstruction, and cholecystectomy with fistula closure may be added if the patient's condition is stable with minimal inflammation and adhesion.

Rare case of gallbladder mucocele causing gastric outlet obstruction treated with cholecystectomy

INTRODUCTION

Gallstone(s) impacted at the distal small bowel causing intestinal obstruction as a result of cholecystoenteric fistula is a well-known, albeit uncommon surgical condition. The rare Bouveret's Syndrome, which refers to the proximal impaction of gallstone(s) in the duodenum or pylorus resulting in the gastric outlet obstruction (GOO), has also been described in the literature. However, gallbladder mucocele with extrinsic compression of the duodenum and/or pylorus causing GOO is a separate entity that is extremely rare.

PRESENTATION OF CASE

A patient who presented with loss of appetite and weight, with intermittent vomiting over a course of eight months was found to have GOO secondary to extrinsic duodenal compression from a large gallbladder mucocele. Surgical intervention in the form of cholecystectomy was performed, and the patient's symptoms resolved post-operatively.

DISCUSSION

We describe an extremely rare case of GOO, which can be easily corrected with cholecystectomy. Removal of the gallbladder removes the root cause of the issue, and should be first line therapy unless the patient is unfit for surgery.

CONCLUSION

This extremely rare cause of GOO should be recognized, and treated promptly with surgery if possible.

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.

Clinical and radiological diagnosis of gallstone ileus: a mini review

Gallstone ileus is a rare cause of bowel obstruction, which mainly affects the elderly population. The associated mortality is estimated to be up to 30%. The presentation of gallstone ileus is notoriously non-specific, and this often contributes to the delay in diagnosis. The diagnosis of gallstone ileus relies on a radiological approach, and herein we discuss the benefits and drawbacks of the use of different modalities of radiological imaging: plain abdominal films, computed tomography, magnetic resonance imaging, and ultrasound scanning. Based on our case experience and review of the literature, the authors conclude that although an effective first-line tool, plain abdominal films are not adequate for diagnosing gallstone ileus. In fact, the gold standard in an acutely unwell patient is computed tomography.

A systematic review of gallstone sigmoid ileus management

INTRODUCTION

Gallstone sigmoid ileus is a rare although serious complication of cholelithiasis resulting in large bowel obstruction. The condition accounts for 4% of all gallstone ileus patients. There are no recognized management guidelines currently. Management strategies range from minimally invasive endoscopy and lithotripsy to substantial surgery. We aim to identify trends when managing patients with gallstone sigmoid ileus to help improve outcomes.

METHODS

Literature searches of EMBASE, Medline and by hand were conducted. All English language papers published from 2000 to 2017(Oct) were included. The terms 'gallstone', 'sigmoid', 'colon', 'ileus', 'coleus' and 'large bowel obstruction' were used.

RESULTS

38 papers included, male:female ratio was 8:30. Average age was 81.11 (SD ± 7.59). Average length of preceding symptoms was 5.31days (+/-SD3.16). 20/38 (59%) had diverticulosis. 89% of patients had significant comorbidities documented. 34/38 patients underwent computerized tomography. 31 stones were located within sigmoid colon, 4 at rectosigmoid junction and 2 within descending colon. Average impacted gallstone size was 4.14 cm (2.3-7 cm range). 23/38 (61%) patients' initial management was conservative or with endoscopy ± lithotripsy. Conservative management successfully treated 26% of patients. 28/38 (74%) patients ultimately underwent surgical intervention. 5/38 patients died post-operatively. Patients treated non-operatively had shorter hospital stays (4:12.3days) although not significant (p-value = 0.0056).

CONCLUSIONS

There is no management consensus from the literature. Current evidence highlights endoscopy and lithotripsy as practical firstline strategies. However, surgical intervention should not be delayed if non-operative measures fail or in emergency. Given the complexity of such patients, less invasive timesaving surgery appears practical, avoiding bowel resection and associated complications.

ATP binding cassette and cholecystokinin A receptor genetic variations in gallstone susceptibility

AIM

It was aimed to assess the association of four polymorphisms and relative haplotypes in the ATP binding cassettes and cholecystokinin A receptor (rs6720173, rs11887534, rs4148217, rs1800857) with the risk of gallstone.

BACKGROUND

Gallstone is a multifactorial disease. Besides high penetrance genes, low or moderate penetrance polymorphisms may increase susceptibility to gallstone.

METHODS

200 gallstone patients and 251 healthy controls were analyzed in a case-control association model. Genotyping was carried out by restriction fragment length polymorphism. Randomly 10% of samples underwent for direct sequencing to confirm results.

RESULTS

Heterozygote variant of rs11887534 demonstrated protective effect on the risk of gallstone susceptibility in males (P=0.013; OR=0.125; CI95%=0.048-0.325). In contrast, C/C genotype associated with gallstone susceptibility in females (P=0.004; OR=5.555 CI95%=1.975-10.632). Moreover, rs1800857 showed association only in females (P=0.019; OR=0.283; CI95%=0.099-0.811). Haplotype analysis for rs1800857 showed GC, CC and CA association with gallstone.

CONCLUSION

The most imperative polymorphisms of contributing genes to gallstone were analyzed in this study and rs11887534 and rs1800857 appeared to be associated with gallstone, which is expected to be further verified in a larger cohort in the future.
