A systematic review 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 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.

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.

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.

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.

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.

The Regularity of the Site of Impaction in Recurrent Gallstone Ileus: A Systematic Review and Meta-Analysis of Reported Cases

Objective

Due to the rarity of recurrent gallstone ileus (RGSI), its epidemiological and clinical features are elusive. With a focus on mortality and the site of impaction, this study consolidates the key clinical characteristics of index GSI (IGSI) and RGSI.

Methods

A meta-analysis of cases reported on RGSI was performed. Risk factors for mortality and site of impaction were examined, and a subgroup analysis was performed for age, sex, and site of impaction (jejunum, ileum, or others).

Results

In the final analysis, 50 (56 individual cases) studies were included. The paired data for the site of impaction was available for 45 patients. Women accounted for 87.3% of all RGSI cases included in the pooled analysis. The median age (interquartile range, IQR) of the patients was 70 (63-76) years, and the median time of recurrence (IQR) was 20.5 (8.5-95.5) days. The overall mortality rate was 11.8%, without correlation between the mortality rate and age, the time of recurrence, or the site of impaction. The region in which the stone was found in RGSI and IGSI was similar in most cases (p=0.002). Logistic regression also revealed a higher probability of stone impaction in the ileum in RGSI if it was the site of impaction in IGSI. In most cases, enterolithotomy was the preferred method.

Conclusions

A high index of suspicion for RGSI should be maintained for older women with a history of GSI. The region where the stone was impacted during IGSI should be investigated first in such patients.

Fibroid expulsion: a unique presentation of mechanical small bowel obstruction 11 years after uterine artery embolization: a case report

Background

Uterine artery embolization in the treatment of uterine leiomyoma has been rarely associated with dislodgement and expulsion of infarcted uterine fibroids through the vagina, peritoneum, or bowel wall, predominantly occurring within 6 months of uterine artery embolization.

Case presentation

We present the case of a 54-year-old African American woman who underwent uterine artery embolization 11 years prior and developed mechanical small bowel obstruction from the migration of fibroid through a uteroenteric fistula with ultimate impaction within the distal small bowel lumen. Small bowel resection and hysterectomy were curative.

Conclusions

Uteroenteric fistula with small bowel obstruction due to fibroid expulsion may present as a delayed finding after uterine artery embolization and requires heightened awareness.

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.

The Tumbling Bullet: Subacute Intestinal Obstruction due to a Retained Bullet

A 29-year-old female presented with multiple gunshot wounds to the back and bilateral lower extremities. The patient underwent an exploratory laparotomy with small-bowel resection of two segments with primary stapled anastomosis and partial nephrectomy. The postoperative course showed prolonged intermittent bowel obstruction secondary to the bullet, which lodged in the distal ileum. The patient eventually passed the bullet; it, however, led to a delay in recovery.

Gallstone ileus: a review

Background Gallstone ileus is an important complication of cholecystolithiasis. In general, surgery is the treatment of choice for such cases, but clinicians face difficulty in the selection of an appropriate approach. Closure of a cholecystoenteric fistula can be achieved through one-stage or two-stage operation. Two-stage operation has a lower mortality rate than a one-stage procedure, but persistence of the cholecystoenteric fistula is associated with the risk of carcinogenesis and recurrence of gallstone ileus.

Objective This study reviews the different surgical approaches according to the impaction site of the gallstone, using data of previous studies by our group and clinical reports in the literature.

Conclusions First, for cases involving impaction at the duodenum, the cholecystoenteric fistula can be repaired in the same surgical field, and one-stage operation obtains favourable outcome; hence, one-stage operation is considered as treatment of choice. Second, for cases involving impaction at the small intestine, natural closure of the cholecystoenteric fistula or low mortality is expected; hence, two-stage operation may be performed, possibly using minimally invasive laparoscopy. Third, for cases involving impaction at the colon, natural closure of the cholecystocolonic fistula is unlikely, and patients have a high risk of reflux cholangitis due to faecal fluid; hence, one-stage operation is considered as treatment of choice.

Cholecystocolonic fistula with a giant colonic gallstone: the mainstay of treatment in an acute setting

A cholecystoenteric fistula (CEF) is a rare complication of cholelithiasis with cholecystitis. Cholecystocolonic fistulas (CCFs) account for 8–26.5% of all CEFs. CCFs can cause colonic bleeding, obstruction or perforation, with such complications being mainly reported in the narrower sigmoid colon. Colonic biliary ileus, or obstruction due to the colonic gallstone impaction, is extremely rare in the proximal colon and its best management is yet to be elucidated. We present the case of a 73-year-old male patient with multiple comorbidities and previous abdominal surgeries who presented with hematochezia and intestinal obstructive symptoms. Imaging revealed a giant 5 × 7 cm² gallstone in the proximal transverse colon. Laparotomy and stone extraction via colotomy were performed. Complicated proximal colonic gallstones are exceedingly rare with several operative and non-operative treatments already described. A time-saving surgery in a patient with serious comorbidities is reasonable when compared to a more extensive procedure including enterolithotomy, cholecystecomy and fistula closure.
