Gallstone ileus: One-stage surgery in an elderly patient: One-stage surgery in gallstone ileus

Gallstone Ileus as an Infrequent Cause of Bowel Obstruction: A Review of Small Cohort

Introduction Gallstone ileus is an uncommon cause of small bowel obstruction; it is a rare complication of calculus chronic cholecystitis which leads to cholecystoenteric fistula and impaction of gallstone in the gastrointestinal tract leading to mechanical bowel obstruction. Our aim is to report the natural history and management of this rare condition in a teaching hospital. Materials and methods It is a retrospective study, where 10 years of data related to the management of intestinal obstruction secondary to gallstone ileus was collected. The cohort included 10 patients, whose demographic data, clinical findings, and management outcomes were evaluated. Results Majority of patients were female (90%, n=9) with a median of 83 years (range 61-96) although 90% of the population were above 70 years. Presenting complaints were mostly pain and vomiting. The onset of symptoms was between two and seven days. The site of obstruction was mostly the ileum (n=9) with the exception of one case in the sigmoid proximal to a benign stricture, and the size of the stone ranged from 2.5 to 4 cm. Moreover, most of the patients had a previous history of gallstone (n=7) with one post-cholecystectomy status. The laboratory investigations in 50% of patients had deranged liver function test (LFT) and acute kidney injury (AKI), and 60% had raised inflammatory markers, namely, white blood cells (WBC) and C-reactive protein (CRP). Intervention as enterolithotomy was the preferred approach (n=8 (two laparoscopic, six open surgery)), and two patients were managed conservatively. The mean postoperative length of stay was 10 days in the open approach and five days in the laparoscopic approach, respectively. Conclusions Elderly female patients are more prone to have gallstone ileus particularly with a past medical history of gallstones, and the preferred management option is enterolithotomy which could be open or laparoscopic depending on the expertise of the surgeon.

Gallstone Ileus: A Rare Cause of Mechanical Bowel Obstruction

A gallstone ileus is a rare cause of mechanical bowel obstruction, accounting for 1% to 4% of all cases. Twenty-five percent of the patients are 65 years of age or older and often present previous significant medical conditions. The authors report the case of an 87-year-old male patient, admitted with the diagnosis of community-acquired pneumonia, who later developed frequent episodes of biliary vomiting, intermittent constipation, and abdominal distension. Abdominal imaging (ultrasound and computed tomography (CT)) showed evidence of a localized inflammatory process in a small bowel loop but excluded vesicular lithiasis. After a failure in the medical approach with antibiotics, an exploratory laparotomy was performed, identifying the intestinal occlusion area, followed by an enterolithotomy at the specific area, and extraction of a 4 cm stone of acellular material. Posteriorly, the patient was treated for three weeks with a carbapenem and physical rehabilitation was promptly initiated with full recovery of his previous status. Gallstone ileus is a very challenging diagnosis and surgery is the treatment of choice. In elderly patients, it is important to promote prompt physical rehabilitation to prevent prolonged bed rest.

Spontaneous resolution of gallstone ileus followed by imaging: A case report and a literature review

Gallstone ileus (GI) is a rare cause of acute abdomen in an emergency setting and a rare complication of cholelithiasis in the elderly, with a female prevalence. Radiologists play a key role in the diagnosis and management of this condition and, with a multimodal approach, diagnostic accuracy usually increases. Spontaneous resolution of GI has previously been reported for stones smaller than 2 cm. Gallstones usually require surgical management; however, in patients with comorbidities and at high risk of surgical complications, a conservative approach may be considered. Herein, we report the case of an 84-year-old woman who came to the emergency department with an acute abdomen pain caused by a GI, with a 2.6 cm gallstone that was revealed on computed tomography and which was followed by diagnostic imaging with spontaneous resolution.

The Diagnosis and Management of Recurrent Gallstone Ileus: A Case Report

Gallstone ileus is one of the rare and insidious causes of small bowel obstruction, which should always be kept in mind by clinicians, especially when encountering older people with a history of gallstones disease. The high mortality and morbidity rate associated with the condition can be mostly attributed to delayed or misdiagnosis. Imaging modalities, particularly CT scans, play an important role in correct and timely diagnosis. We present the case of a 65-year-old man with a two-year history of colicky biliary pain, who had severe abdominal pain with obstructive symptoms for five days before admission. The diagnosis of gallstone ileus is made using CT scan findings. Enterolithotomy alone was performed three days later. A second, smaller migrated gallstone was also found, which excreted spontaneously. After 20 days, the patient achieved full recovery and was discharged.

FORECASTING THE DEVELOPMENT OF PURULENT-INFLAMMATORY POSTOPERATIVE COMPLICATIONS IN PATIENTS WITH OBSTRUCTIVE BOWEL OBSTRUCTION

OBJECTIVE

The aim: The purpose of the study is to improve the results of treatment of patients with acute intestinal obstruction of tumor origin by developing individualized surgical tactics considering the level of cryoglobulins.

PATIENTS AND METHODS

Materials and methods: 96 patients with ileus of tumor origin were studied. The mean age of patients was 54.7 ± 5.9 years. 30 patients were diagnosed with colorectal cancer, 35 patients - with sigmoid cancer, 13 patients - with cecum and ascending colon, 11 patients - with transverse colon cancer, and 7 patients with descending colon cancer. Isolation of cryoglobulins from blood serum was performed by the method of A. E. Kalovidoris with modifications. The content of Ig A, Ig M, Ig G, total Ig E in the serum was investigated using enzyme-linked immunosorbent assay systems "Granum-Ukraine", the content of allergen-specific Ig E was investigated using enzyme-linked immunosorbent assay systems produced by "Microgen".

RESULTS

Results: As a result of treatment of 96 patients, it was found that the level of development of postoperative purulent complications was significantly influenced by the level of cryoglobulinemia and the volume of surgery (CMU, p <0.05). It was found that in patients with decompensated intestinal obstruction, the initial concentration of cryoglobulins was 16.4% higher than in the group with compensated intestinal obstruction (CMU, p <0,05).

CONCLUSION

Conclusions: Determination of cryoglobulinemia on admission of patients with acute obstructive ileus of tumor origin is a simple and effective method for predicting the development of purulent-inflammatory complications in the postoperative period and can influence the choice of treatment tactics.

Propensity score matching between conventional laparoscopic cholecystectomy and indocyanine green cholangiography-guided laparoscopic cholecystectomy: observational study

The injury of common bile duct (CBD) is one of the most common complications during laparoscopic cholecystectomy. Consequences of CBD injury are grave since CBD is the only pathway of bile from biliary tracts to duodenum. When CBD injury occurs, extra surgical procedures repairing CBD or reconstructing biliary tracts have to be performed on patients, which increase expenses of patients and physical trauma. A total of 238 patients undergoing laparoscopic cholecystectomy (LC) in Zhuhai People's Hospital from July 2020 to April 2021 were enrolled in this observational study, including 126 patients undergoing conventional LC and 112 patients undergoing ICG angiography-guided LC. Method of propensity score matching was used to balance the preoperative data of patients in the two groups. For both groups, the "Critical View of Safety" (CVS) was introduced. For the ICG group, the CBD, cystic duct (CD), and gallbladder were identified using near-infrared (NIR) ray. Intraoperative blood loss, operation time, postoperative hospitalization time, and the incidence rate of intraoperative complications were compared between the two groups. ICG angiography in LC shows safe and effective outcomes. The intraoperative blood loss, operation duration, postoperative hospitalization time, and complication incidence rate of the ICG group are significantly lower than those of the conventional group. ICG angiography in LC was a useful and effective method to identify the CBD and prevent intraoperative complications. Registration at Chinese Clinical Trial Registry, No: ChiCTR1900024594.

Bowel obstruction secondary to gallstone ileus within an inguinoscrotal hernia: a rare diagnosis in an elderly patient

Gallstone ileus and obstructed inguinal hernias are respectively, rare and common causes of small bowel obstruction. There are no published cases of these pathologies occurring simultaneously. Here, we describe a unique case of an elderly male patient presenting with a small bowel obstruction caused by these combined pathologies. Following an acute presentation with obstructive symptoms, a CT scan demonstrated small bowel obstruction due to a large gallstone lodged in the neck of an inguinoscrotal hernia with associated pneumobilia. The case may have been managed conservatively if it was not for the presence of the gallstone. Previous imaging had incidentally demonstrated gallstones in the gallbladder and a large uncomplicated right inguinoscrotal hernia. It is presumed that a cholecystoduodenal fistula formed and a gallstone then migrated downstream to lodge within the neck of the inguinoscrotal hernia. This case underscores the concept that even in the presence of an “obvious” cause of small bowel obstruction, such as an irreducible, large inguinoscrotal hernia, we must always maintain a healthy clinical skepticism and an open mind to other unexpected aetiologies, which may account for the clinical presentation that might impact subsequent management.

Gallstone ileus: a rare type of intestinal obstruction in Ghana

Gallstone ileus is an uncommon cause of intestinal obstruction in Ghana. A patient with gallstone ileus that was diagnosed intra-operatively after being treated conservatively as adhesive small bowel obstruction for ten days is reported to highlight the importance of the clinical information in this condition. A 60-year-old Chinese male with recurrent intestinal obstruction who was initially being managed at a primary healthcare facility was subsequently referred to a tertiary hospital on account of computer tomography diagnosis of an intraluminal object obstructing the bowel. He had hypokalaemia that was corrected before surgery. Intra-operatively, a 4.5cm in diameter gallstone was removed from the terminal ileum. Gallstone ileus is rare in Ghana. A high index of suspicion is required to avoid a delay in diagnosis due to the low incidence of cholelithiasis in Ghana.

Bouveret's syndrome: a strategic approach for management

An 81-year-old woman, diabetic and hypertensive, presented with nausea and intermittent vomiting. She had dysphagia and loss of appetite for over 6 weeks and significant weight loss over 3 weeks and was admitted in general surgery unit on emergency basis. Investigations revealed dilated stomach and a stone in first part of duodenum, with probable site of obstruction at level of first part of duodenum, secondary to a cholecystoduodenal fistula. With a preoperative diagnosis of Bouveret's syndrome, she underwent laparotomy and subtotal cholecystectomy. Postoperative recovery was delayed due to gastroparesis and delayed gastric emptying which resolved with conservative management. Successful management of this case required a multidisciplinary team approach. Early diagnosis was the key to management. Mode of treatment and management of Bouveret's syndrome should be tailored to suit patient's age, comorbidities and performance status.

Propensity score-matching analysis for single-site robotic cholecystectomy versus single-incision laparoscopic cholecystectomy: A retrospective cohort study

BACKGROUND

Although the single-site robotic cholecystectomy(SSRC) has been performed with expectation of overcoming the limitation of single-incision laparoscopic cholecystectomy(SILC), there exists a lack of comparison studies involving SILC and SSRC. This study aimed to analyze surgical outcomes of single-site robotic cholecystectomy and single-incision laparoscopic cholecystectomy by propensity score-matching analysis.

MATERIALS AND METHODS

From March 2009 to August 2015, 290 consecutive patients underwent SSRC or SILC at Severance Hospital, Seoul, Korea. Potential confounding factors for operative outcomes were adjusted by propensity score-matching analysis. One hundred four patients from each group were evaluated for perioperative outcomes and compared for a retrospective cohort study.

RESULTS

There was no difference in potential cofounders such as gender, age, body mass index (BMI), and perioperative cholecystitis-related symptoms between two groups after propensity score-matching. However, mean operation time was shorter (56.69 ± 13.65 vs. 101.57 ± 27.05 min; p < 0.001) and median bleeding amount during surgery was less (0 (0-50) vs. 0 (0-100) mL; p < 0.001) in the SILC group. There was no significant difference between the two groups regarding conversion to conventional multiport cholecystectomy. Bile leakage due to perforation of the gallbladder during surgery was more common in the SILC group (6.7% vs. 17.3%; p = 0.019). Moreover, bile spillage rate was significantly increased in conjunction with a higher BMI in the SILC group, whereas BMI did not affect the bile leakage rate in the SSRC group.

CONCLUSIONS

SSRC is not superior to SILC except regarding bile spillage incidence. However, the technical stability and clinically undetected advantages of SSRC are expected to prompt surgeons to perform this more reliable procedure.

Gallstone ileus managed with enterolithotomy

Although gallstone disease is classically associated with the inflammatory sequela of cholecystitis, other presentations include gallstone ileus, Mirizzi syndrome, Bouveret syndrome and gallstone ileus. Gallstone ileus occurs when a gallstone passes from a cholecystoduodenal fistula into the gastrointestinal tract and causes obstruction, usually at the ileocaecal valve. It represents an uncommon complication of cholelithiasis, accounting for 1%-4% of all cases of mechanical bowel obstruction and 25% of all cases in individuals aged >65 years. It has a female predilection. Clinical presentation depends on the site of the obstruction. Diagnosis can prove challenging with the diagnosis rendered in 50% of cases intraoperatively. The authors present the case of a 79-year-old woman with a 10-day history of abdominal pain, nausea, vomiting and episodes of loose stools. An abdominal radiograph showed mildly distended right small bowel loops. Further investigation with a CT of the abdomen and pelvis demonstrated small bowel obstruction secondary to a 3.3 cm calculus within the small bowel. She underwent a laparotomy and a 5.0×2.5 cm gallstone was evident, causing complete obstruction. An enterolithotomy was performed. Her postoperative course was complicated by Mobitz type II heart block requiring pacemaker insertion. This paper will provide an overview of the clinical presentation, investigations and management of gallstone ileus. It provides a cautionary reminder of considering gallstone ileus in the differential diagnosis in elderly patients presenting with bowel obstruction and a history of gallstone disease.

An emergency case of small bowel obstruction due to multiple gallstones in a limited resource setting

•

Gallstone ileus is a rare condition accounting for 5% of all intestinal obstruction cases in which the mortality rate is relatively high (25%).

•

Preoperative diagnosis is a major challenge because the symptoms are unspecific and diagnosis is often established intraoperatively.

•

Surgical treatment with enterolithotomy alone is recommended for geriatric patients with concomitant comorbidities.

•

Enterolithotomy alone might also be suitable in the case of emergency because of less clinical complications and comparable outcomes.

Introduction

Gallstone ileus is an uncommon intestinal obstruction caused by impaction of gallstones passing through the cholecysto-intestinal fistula. Diagnosis of gallstone ileus remains a major challenge because the symptoms and signs are unspecific and the recommended laboratory examinations are not always available particularly in limited health resource settings including in Indonesia. In addition, treatment of choice is still debatable involving enterolithotomy only with or without additional cholecystectomy and fistula repair in one or two-stage surgery.

Presented case

A 49 years old overweight Javanese woman presented in the emergency room with nausea, frequent vomiting, abdominal distension, and absence of defecation in the past 3 days before admission. Previous abdominal surgery and history of biliary disease were not reported during anamnesis. Plain abdominal X-rays revealed small bowel obstruction. Upon emergency laparotomy, the mechanical bowel obstruction was caused by multiple gallstones in the terminal ileum.

Discussion

Although the incidence of gallstone ileus is 5% of all intestinal obstruction cases, the mortality rate is around 25%. Diagnosis is often difficult and half of the cases are diagnosed intraoperatively. Surgical management is still controversial involving enterolithotomy with or without cholecystectomy and fistula repair in one or two stage procedure.

Conclusions

Although the incidence is rare, elaborating thorough anamnesis, physical and basic laboratory examinations in gastrointestinal obstruction should consider gallstone ileus as a potential differential diagnosis particularly in a patient with any risk factors of the biliary disease. Enterolithotomy only might be acceptable for any emergency case due to the equivalent clinical outcomes and relatively low complications.

Small bowel obstruction with multiple perforations post chestnut ingestion

Phytobezoars are a rare cause of small bowel obstruction (SBO), which consists of vegetable matter such as seeds, skins, fibres of fruit and vegetables that have solidified. We present the case of a 61-year-old man with no previous surgery who presented with central abdominal pain, nausea and vomiting. An abdominal CT scan demonstrated SBO with a transition point in the left anterior abdomen. He proceeded to a laparoscopy, which revealed multiple perforations throughout the small bowel, from the proximal jejunum to the terminal ileum. Laparotomy was performed, and undigested chestnuts were milked out through the largest perforation and the perforations were oversewn. While obstruction due to phytobezoars is rare, this case demonstrates the importance of considering small bowel trauma and perforation due to phytobezoars and highlights the need for close inspection of the entire gastrointestinal tract for complications in the setting of phytobezoar-related bowel obstruction.

Buried coin in the gastric mucosa

A 29-year-old man presented to the Accident and Emergency department with abdominal cramping following ingestion of a 50 p coin 2½ weeks prior to presentation. He had not observed it pass in his stools. An abdominal radiograph confirmed the presence of the 50 p coin in his stomach. Subsequently, he had an oesophagogastroduodenoscopy (OGD) performed with a failure to visualise the coin. 1½ weeks later, he returned to the department as he was still unable to observe its passing in his stools. A repeated abdominal radiograph and a CT of the abdomen and pelvis revealed that the coin was still in his stomach. A second OGD was performed once again with a failure to visualise the coin. It appeared that the coin had migrated into his gastric mucosa.

Stone in the distal jejunum presenting as small bowel obstruction: A case report

INTRODUCTION

Gallstone ileus is a rare presentation of cholelithiasis accounting for around 4% of cases of small bowel obstruction under 65 years of age but rises to 25% in those more than 65 years of age. Most gall stones, if impact in the bowel, are seen to lodge at the ileocecal valve as this is the most narrow part of the bowel.

PRESENTATION OF CASE

We present a case of small intestinal obstruction because of a gallstone stuck in the distal jejunum. Patient was explored and one-stage surgery was done i.e. cholecystectomy, enterotomy and stone retrieval, and fistula repair. Our patient had uneventful postoperative recovery and was discharged after a week.

DISCUSSION

Gallstone ileus is a rare entity presenting a significant diagnostic challenge to surgeons due to lack of specific findings. Moreover, the surgical management options to be adopted are diverse and depend upon the condition of the patient. Stable patients can be managed with two-stage procedures i.e. enterotomy and stone retrieval earlier with cholecystectomy in an elective setting. Our patient was managed with one-stage procedure i.e. cholecystectomy was done in the same setting and our patient did well.

CONCLUSION

Gallstone ileus needs to be kept in the differential diagnosis list of intestinal obstruction in middle aged patients even in the absence of history of gallstones as this may be the first presentation of gallstone disease.

Haemorrhagic cholecystitis: a rare entity not to be forgotten

Haemorrhagic cholecystitis is a rare entity of acute cholecystitis that carries a high morbidity and mortality rate if management is delayed. Its clinical course can mirror that of acute cholecystitis. Characteristic findings on ultrasound or CT scan are useful clues to early diagnosis. Urgent cholecystectomy is required prior to progressing to perforation of gallbladder. Most of the literature are case reports with causes associated with anticoagulation. Herein, we described a morbidly obese patient with poorly controlled diabetes presenting with non-specific right upper quadrant pain and was subsequently diagnosed with haemorrhagic cholecystitis. A review of the literature was also performed to summarise the potential clinical presentations, distinctive imaging findings and management options available for this rare condition.

Spontaneous gall bladder perforation with ischaemic bowel disease: a rare cause of acute abdomen with pneumoperitoneum in elderly

Perforation of the gall bladder can occur due to a complication of acute (in 3%-10%) or chronic cholecystitis, presenting with or without gallstones. Other causes include trauma, neoplasms, steroid therapy or vascular compromise. In 1934, Niemeier classified the condition into three types: type I, acute perforation into the free peritoneal cavity; type II, subacute perforation with abscess formation; and type III, chronic perforation with fistula formation between the gall bladder and another viscus with type I experiencing the highest mortality rate. In particular, there are very few cases of gall bladder perforation associated with ischaemic bowel disease. We present a case of type I gall bladder perforation in a 70-year-old woman, without any apparent comorbidities, presenting with acute abdomen consistent with perforated duodenal ulcer with pneumoperitoneum on a plain abdominal radiograph and contrast-enhanced CT with eventual discovery of fundal perforation and ischaemic small bowel at laparotomy.

Gall stone ileus: Unfamiliar cause of bowel obstruction. Case report and literature review

INTRODUCTION

Gallstone ileus is a rare sequela of cholelithiasis. The pathology occurs as a result of bilioenteric fistula due to erosion by the offending gallbladder stone. It is most commonly encountered in elderly females and CT imaging is diagnostic in the majority of cases. Surgical intervention aims to promptly relief the obstruction by removing the gallstone and dealing with the fistula. Morbidity and mortality are usually high since it usually occurs in elderly patients.

PRESENTATION OF CASE

An 88-year-old lady with multiple chronic medical problems and no history of biliary manifestation presented with acute small bowel obstruction. Abdominal CT imaging revealed a bilioenteric fistula and an impacted gallstone in the jejunum causing occlusion. Laparotomy was performed and the stone was removed via enterolithotomy. Manipulation of the cholecystoduodenal fistula was not attempted due to severe inflammatory adhesions. The patient had uneventiful postoperative course and remained symptom free on one year follow-up.

DISCUSSION AND CONCLUSION

Management of gallstone ileus is mainly surgical. Delay in detection and treatment of gallstone ileus may result in significant morbidity and mortality. The choice of surgical option is influenced by the preoperative medical status of the patient. A literature review generally supports the employment of enterolithotomy in high-risk patients and reserving cholecystectomy and resection of the fistula for less comorbid patients with feasible anatomy.

Intraoperative cholangiography during cholecystectomy in sequential treatment of cholecystocholedocholithiasis: To be, or not to be, that is the question A cohort study

BACKGROUND

Choledocholithiasis occurs in 10-15% of patients with cholecystolithiasis. Despite the existence of many therapeutic options for the treatment of cholecystocholedocholithiasis, a sequential treatment in which pre-operative ERCP is combined with intraoperative cholangiography (IOC) and laparoscopic cholecystectomy (LC), is the most commonly accepted strategy. However, use of IOC in the "splitting treatment" of cholecystocholedocholithiasis is controversial. The aim of the present study is to investigate the utility of IOC in detecting residual stones in patients undergoing LC in the sequential treatment of common biliary duct or gallbladder stones.

METHODS

Patients were recruited retrospectively among those who underwent IOC during LC, performed as second stage in the sequential treatment for cholecystocholedocholithiasis between 2010 and 2016. Demographic and clinical data were obtained from CPT codes at Ospedale Monaldi A.O.R.N dei Colli Naples, Italy. Data obtained from all pre-operative ERCP analyses were recorded, including cholangiogram findings and performance of sphincterotomy. Statistical analysis was carried out using the IBM SPSS Statistic 19.0 software package.

RESULTS

Between January 2010 and December 2016 575 patients (343 males, 242 females) underwent IOC during LC for symptomatic cholecystitis due to cholelithiasis. Among patients accrued for the study, 143 underwent preoperative ERCP for suspicion of common biliary duct stones. At the time of pre-operative ERCP, 123 were found to have common biliary duct stones while 20 (15%) presented negative ERCP. Complete removal of stones was accomplished in 119 patients. Among these patients, 13 had residual common biliary duct stones diagnosed by IOC (11%). Two patients underwent laparoscopic bile duct revision and, last, two patients were referred for ERCP at a later point. It is of note that all patients who presented residual stones by IOC had undergone pre-operative sphincterotomy.

CONCLUSION

This study demonstrates that IOC is particularly effective in detecting residual stones in patients undergoing LC in sequential treatment of common biliary duct and/or gallbladder stones, and may be used on a routine basis in the sequential treatment of cholecystocholedocholithiasis.

Gallstone ileus: monocentric experience looking for the adequate approach

Common complications of biliary lithiasis are cholecystitis, bile duct lithiasis, and acute biliary pancreatitis. Gallstone ileus is uncommon complications often requiring surgical approach. It is a mechanical bowel obstruction caused by a biliary calculus usually originating from a bilioenteric fistula. Because of the limited number of reported cases, the optimal surgical method of treatment has been the subject of ongoing debate. A retrospective, observational, descriptive study was conduct on patients diagnosed with non-neoplastic bowel occlusion. For each case of gallstone ileus, the following variables were revised: personal and clinical data, mean time of onset of symptoms, length of pre- and postoperative stay, imaging studies, biochemical tests, site of the bilioenteric fistula and occlusion, surgical strategy, postoperative course, follow-up, and mortality. Of the 290 cases of non-neoplastic bowel obstruction from 2008 to 2015, 11 (3.7%) were due to gallstone ileus. The majority of patients were elderly women (F 9/M 2) with high average age (82.4; 76-88) and significant comorbidities. Five cases of small-bowel occlusions were treated with solely enterolithotomy. For the remaining six cases, digestive resection and cholecystectomy were performed. Complications rate (20 vs. 80%) and postoperative stay (12.4 vs. 25.3 days) were lower in the group of enterolithotomy with respect to the group treated with other procedures. In-hospital mortality was nil. Gallstone ileus is an uncommon bowel occlusion affecting mainly the elderly female population. Enterotomy with stone extraction alone is associated with better outcomes than more invasive techniques.

Differentiation between gallbladder cancer with acute cholecystitis: Considerations for surgeons during emergency cholecystectomy, a cohort study

PURPOSE

Gallbladder cancer (GBCA) is an uncommon malignancy with vague and non-specific symptoms. GBCA is sometimes diagnosed after emergency cholecystectomy for acute cholecystitis. We investigated the differential diagnosis between GBCA with acute cholecystitis.

MATERIALS AND METHODS

Thirteen patients were diagnosed with GBCA after emergency cholecystectomy carried out for acute cholecystitis. A radiologist who was blinded to the final diagnoses retrospectively reviewed the computed tomography (CT) scans of the patients with GBCA and 25 patients with acute cholecystitis. We retrospectively reviewed the medical records of these patients and compared the clinical characteristics and CT findings between patients with GBCA and those with acute cholecystitis. We also investigated the prognostic factors in patients with GBCA who underwent emergency cholecystectomy.

RESULTS

Gallbladder (GB) stones were found more often in patients with acute cholecystitis (n = 17, 68%) than in patients with GBCA (n = 7, 53.8%) (p = 0.486). Patients with GBCA showed typical GB masses or focal enhanced wall thickening when compared to diffuse wall thickening in patients with acute cholecystitis. Some GBCA patients showed irregular mural thickening and GB enhancement. Differentiating carcinoma from acute cholecystitis might sometimes not possible, but the latter group of patients had significantly lower C-reactive protein (CRP) levels (p = 0.033) and less regional fat stranding (p = 0.047). Survival was significantly affected by aggressive tumor characteristics (lymphatic invasion [p = 0.025], depth of tumor invasion [p = 0.004]) or R0 resection (p = 0.013) rather than bile spillage (p = 0.112).

CONCLUSIONS

Surgeons deciding on emergency cholecystectomy for elderly patients with acute cholecystitis must suspect GBCA in patients with a low CRP level, irregular mural thickening or enhancement of GB without regional fat stranding.

Gallstone Ileus: Dilemma in the Management

Gallstone ileus is a mechanical intestinal obstruction caused due to impaction of a large gallstone within the bowel. The ideal treatment of gallstone ileus remains controversial, with the main dilemma being between a one-stage and a two-stage surgical procedure. A 69-year old male patient presented with gallstone ileus. A one-stage procedure with enterolithotomy and primary closure of duodenal fistula was done. His immediate postoperative recovery was uneventful, but after 3 weeks of surgery, he developed respiratory complications and expired of multi-organ failure. In gallstone ileus, patient presents with symptoms of intestinal obstruction. Enterolithotomy alone remains the most common operative method, but the definitive surgical management is still under research. An intraoperative dilemma between a one-stage or two-stage surgery is difficult to resolve in absence of clear guidelines. Hence, more studies are required to come to a consensus in deciding its definitive management.

Gallstone ileus: An overview of the literature

INTRODUCTION

Gallstone ileus represents 4% of the causes of bowel obstruction in the general population, but increases to 25% in patients above the age of 65 years. Gallstone ileus does not present with unique symptoms, making diagnosis difficult. Its management is surgical, but there is no consensus as to which of the different surgical techniques is the procedure of choice. At present, there is no recent review of this pathology.

AIM

To conduct an up-to-date review of this disease.

MATERIALS AND METHODS

Articles published within the time frame of 2000 to 2014 were found utilizing the PUBMED, EMBASE, and Cochrane Library search engines with the terms "gallstone ileus" plus "review" and the following filters: "review", "full text", and "humans".

RESULTS

The results of this review showed that gallstone ileus etiology was due to intestinal obstruction from a gallstone that migrated into the intestinal lumen through a bilioenteric fistula. The presence of 2 of the 3 Rigler's triad signs was considered diagnostic. Abdominal tomography was the imaging study of choice for gallstone ileus diagnosis and the surgical procedures for management were enterolithotomy, one-stage surgery, and two-stage surgery. Enterolithotomy had lower morbidity and mortality than the other 2 procedures.

CONCLUSIONS

The aim of gallstone ileus treatment is to release the obstruction, which is done through enterolithotomy. It is the recommended technique for gallstone ileus management because of its lower morbidity and mortality, compared with the other techniques.

Age-related differences pre-, intra-, and postcholecystectomy: A retrospective cohort study of 6,868 patients

BACKGROUND

Cholecystectomy (CCY) is increasingly performed in older individuals. We sought to examine age-related differences in pre-, intra-, and postoperative factors at a community hospital, using a very large, single-institution cholecystectomy database.

MATERIALS AND METHODS

A retrospective review of 6868 patients who underwent CCY from 2001 to 2013 was performed. ROC analysis identified the optimal age cutoff when complications reached a significant inflection point (<55 and ≥55 years). Multiple clinical features and outcomes were measured and compared by age. Logistic regression was used to examine how well a set of covariates predicted postoperative complications.

RESULTS

Older patients had significantly higher rates of comorbidities and underwent more extensive preoperative imaging. Intraoperatively, older patients had more blood loss, longer operative times, and more open operations. Postoperatively, older patients experienced more complications and had significantly different pathological findings. While holding age and gender constant, regression analyses showed that preoperative creatinine level, blood loss and history of previous operation were the strongest predictors of complications. The risk for developing complications increased by 2% per year of life.

CONCLUSION

Older patients have distinct pre-, intra-, and postoperative characteristics. Their care is more imaging- and cost-intensive. CCY in this population is associated with higher risks, likely due to a combination of comorbidities and age-related worsened physiological status. Pathologic findings are significantly different relative to younger patients. While removing the effect of age, preoperative creatinine levels, blood loss, and history of previous operation predict postoperative complications. Quantifying these differences may help to inform management decisions for older patients.

Bowel obstruction and perforation due to a large gallstone. A case report

•

Gallstone obstruction is a rare clinical entity presenting usually in elderly patients and is associated with a medical history of biliary symptoms.

•

CT examination uncovered all findings consisting Rigler’s triad, thus air in the gall bladder, bowel obstruction and a gallstone inside the bowel lumen. It also identified a cholecystoduodenal fistula.

•

Rupture of the small bowel occurred intraoperatively, and a large 3.2 cm gallstone was located in the terminal ileum, which was recovered.

•

Post-surgical recovery was uneventful with no further report of obstruction symptoms at 6 month follow up.

Introduction

Gallstone bowel obstruction is a rare form of mechanical ileus usually presenting in elderly patients, and is associated with chronic or acute cholecystitis episodes.

Case presentation

We present the case of an 80 year old female with abdominal pain, inability to defecate and recurrent episodes of diarrhea for the past 8 months. CT examination uncovered a cholecystoduodenal fistula along with gas in the gall bladder and the presence of a ≥2 cm gallstone inside the small bowel lumen causing obstruction. Patient was admitted to the operating room, where a 3.2 cm gallstone was located in the terminal ileus. A rupture was found in the antimesenteric part of a discolored small bowel segment, approximately 60 cm from the ileocaecal valve, through which the gallstone was recovered. The bowel regained its peristalsis, and the rupture was debrided and sutured. Patient was discharged uneventfully on the 6th postoperative day.

Discussion

Gallstone ileus is caused due to the impaction of a gallstone inside the bowel lumen. It usually passes through a fistula connecting the gallstone with the gastrointestinal tract. It can present with nonspecific or acute abdominal symptoms. CT usually confirms the diagnosis, while there are a number of treatment options; conservative, minimal invasive and surgical. Our patient was successfully relieved of the obstruction through recovery of the gallstone using open surgery, with no repair of the fistula.

Conclussion

Although rare, gallstones must be suspected as a possible cause of bowel obstruction, especially in elderly patients reporting biliary symptoms.

An Unusual Presentation of Gallstone Ileus: A Red-Herring or Missed Diagnosis

BACKGROUND

Gallstone ileus is a rare complication of chronic calcular cholecystitis and an uncommon etiological entity responsible for mechanical intestinal obstruction. The most common obstructed part is the narrow terminal ileum, whereas the jejunum is rarely affected. The gallstone is postulated to reach the small bowel by gradual erosion from the gall bladder, most commonly into the duodenum, forming a cholecysto-duodenal fistula.

CASE REPORT

Herein, we report a 72-year-old male who presented with intestinal obstruction of a 5-day duration, with a clinical diagnosis of an irreducible inguinal hernia. However, the patient continued to be symptomatic following an uncomplicated hernioplasty. A computerized tomography (CT) scan of the abdomen revealed a small bowel lesion, which intra-operatively was confirmed to be an impacted gallstone in the jejunum with a cholecysto-duodenal fistula.

CONCLUSIONS

Despite gallstone is uncommon cause of intestinal obstruction, a high index of suspicion with a careful CT scan interpretation is the key to the diagnosis, especially when there is a red-herring distracting the attention, like irreducible hernia in this case.

Karewsky syndrome: A case report and review of the literature

INTRODUCTION

Gallstone ileus can be a lethal disease, rarely suspected in the clinical scenario. It represents about 25% of all bowel obstruction cases in patients older than 65. There is a classification of gallstone ileus based on the onset time: acute, subacute and chronic (Karewsky syndrome). We describe the first reported case of chronic gallstone ileus.

CASE PRESENTATION

A 78-year-old female was admitted to the ER with a 15-day case of consistent bowel obstruction. The subject reported a five-year history of recurrent hospital admissions that resolved spontaneously after non-surgical management. Karewsky syndrome was diagnosed and managed with enterolithotomy. After five days of postoperative evolution the patient was discharged, and at six months follow up, no other hospital admission or relapse has been registered.

DISCUSSION

The gallstone ileus diagnosis demands a higher clinical suspicion, there is no biochemical marker, and an abdominal CT is ideal for imaging-based diagnosis. There is no consensus on the optimal surgical approach.

CONCLUSION

We describe the first case of Karewsky syndrome and a gastro-jejune and gastric-choledochus double fistula. We emphasize the importance of higher clinical suspicion for patients with bowel obstruction older than 65 years old and make evident that although there are not evidence-based guidelines for this treatment, enterolithotomy is a recommended approach.

Acute intestinal obstruction due to gallstone ileus

OBJECTIVE

To perform a systematic review of the history, available image exams and clinical approach to the diagnosis and treatment of gallstone ileus.

METHOD

Retrospective study in a university hospital including all cases of SBO treated over a period of 23 years. According to the surgical treatment the patients were divided into two groups: (1) enterolithotomy with cholecystectomy performed later (two-stage surgery); and (2) enterolithotomy, cholecystectomy and fistula closure (one-stage surgery).

RESULTS

Twelve patients were included in the study, including 11 females (91,6%), with a mean age of 72.2 years. All patients presented associated diseases, mainly arterial hypertension (75%). All except one patient had multiple SBO symptoms. Gallstone ileus diagnosis was achieved in six patients (50%) before laparotomy. There were 8 patients in group 1 and 4 in group 2, and the morbidity was, respectively, 33.3% and 8.3%. Overall mortality was 16.6% (one patient in each group).

CONCLUSIONS

Gallstone ileus should be suspected in the elderly with SBO symptoms. Early diagnosis can reduce post-operative complications. Treatment is urgent laparotomy, and surgical treatment must be individualized for each case. The majority of patients in this study were treated with enterolithotomy, with cholecystectomy being performed later in two symptomatic patients.

Metastatic breast cancer presenting as a gallstone ileus

Metastatic breast cancer to the small bowel (SB) presenting as gallstone ileus and resulting in SB obstruction has not been described previously. A 76-year-old woman with previous metastatic breast cancer to the axial spine and hips presented with abdominal pain and bilious vomiting. CT scanning revealed SB obstruction consistent with gallstone ileus. The patient underwent two segmental SB resections for distal ileal strictures mimicking what appeared to be macroscopic Crohn's disease. The entero-biliary fistula was undisturbed. Pathological analysis revealed the dual pathologies of gallstone ileus and metastatic carcinoma from a breast primary causing luminal SB obstruction. Improvements in staging and treatment modalities have contributed to the increased overall long-term survival for breast cancer, compelling clinicians to consider metastatic breast cancer as a differential diagnosis in women presenting with new onset of gastrointestinal symptoms in order that appropriate treatment be administered in a timely fashion.
