Clinical patterns of postcholecystectomy syndrome

Open versus laparoscopic completion cholecystectomy in patients with previous open partial cholecystectomy: a retrospective comparative study

Background

Some patients report recurrence or persistence of their manifestations after cholecystectomy, and retained gallstones may be a relevant etiology for their complaint. Completion cholecystectomy is advised for these cases to alleviate their manifestations. No previous studies have compared the outcomes of open versus laparoscopic outcomes in these patients, especially in patients who had initial open partial procedures. That is why we performed this study to report the perioperative outcomes of the two approaches in such patients.

Methodology

This is a retrospective analysis of 80 patients who had a completion cholecystectomy in the authors' center (40 open and 40 laparoscopic cases) after initial open partial cholecystectomy.

Results

The duration elapsed since the primary procedure had an average of 18 months in the open group and 21 months in the laparoscopic group. Abdominal pain and dyspepsia were the most common presentations. Some patients had stump cholecystitis or jaundice. The intraoperative assessment revealed either the residual gallbladder or a long cystic duct stump. Laparoscopy yielded shorter operative time, earlier oral intake, and shorter hospitalization periods compared to the open approach (P<0.05). The latter was associated with a 20% wound infection rate that was never encountered after laparoscopy (P =0.003).

Conclusion

Previous open partial cholecystectomy does not hinder subsequent laparoscopic completion cholecystectomy. Additionally, laparoscopy is associated with better perioperative outcomes than the open approach.

Routine upper gastro-intestinal tract endoscopy before elective cholecystectomy for symptomatic gallstones-justified

Gallstones are common in Western countries and increasing in developing countries through adoption of western lifestyle. Gallstones may cause life-threatening complications, including acute cholecystitis, acute cholangitis, and acute pancreatitis. Cholecystectomy is the treatment of choice for symptomatic gallstones. Presentation of symptomatic gallstones may be indistinguishable from that of other upper gastro-intestinal tract (UGI) pathologies. Some surgeons routinely perform preoperative UGI endoscopy to diagnose and treat concomitant UGI pathology. A prospective cross-sectional observational study was undertaken at University of Pretoria teaching hospitals to evaluate this practice. Patients aged 18 years and older, with symptomatic gallstones but did not satisfy Tokyo guidelines for acute cholecystitis were recruited. UGI endoscopy was performed before cholecystectomy. There were 124 patients, 110 (88.7%) females and 14 (11.3%) males, mean age 44.0 (13.2) (range: 22-78) years. Most common symptoms were right upper quadrant (RUQ) pain (87%), epigastric pain (59.7%), nausea (58.1%) and vomiting (47.9%). Clinically, 80% had RUQ tenderness and 52.4% epigastric tenderness. UGI endoscopy found 35.4% pathology, 28.2% were active, and comprised acute gastritis (27.4%), peptic ulcers (4.8%), duodenitis (3.2%) and oesophagitis (2.4%). Twelve patients had more than one pathology. This warranted treatment before elective cholecystectomy and justifies the practice of routine preoperative UGI endoscopy.

Effect of simethicone for the management of early abdominal distension after laparoscopic cholecystectomy: a multicenter retrospective propensity score matching study

OBJECTIVE

To investigate whether simethicone expediates the remission of abdominal distension after laparoscopic cholecystectomy (LC).

METHODS

This retrospective study involved LC patients who either received perioperative simethicone treatment or not. Propensity score matching (PSM) was employed to minimize bias. The primary endpoint was the remission rate of abdominal distension within 24 h after LC. Univariable and multivariable logistic regression analyses were conducted to identify independent risk factors affecting the early remission of abdominal distension after LC. Subsequently, a prediction model was established and validated.

RESULTS

A total of 1,286 patients were divided into simethicone (n = 811) and non-simethicone groups (n = 475) as 2:1 PSM. The patients receiving simethicone had better remission rates of abdominal distension at both 24 h and 48 h after LC (49.2% vs. 34.7%, 83.9% vs. 74.8%, respectively), along with shorter time to the first flatus (14.6 ± 11.1 h vs. 17.2 ± 9.1 h, P < 0.001) compared to those without. Multiple logistic regression identified gallstone (OR = 0.33, P = 0.001), cholecystic polyp (OR = 0.53, P = 0.050), preoperative abdominal distention (OR = 0.63, P = 0.002) and simethicone use (OR = 1.89, P < 0.001) as independent factors contributing to the early remission of abdominal distension following LC. The prognosis model developed for predicting remission rates of abdominal distension within 24 h after LC yielded an area under the curve of 0.643 and internal validation a value of 0.644.

CONCLUSIONS

Simethicone administration significantly enhanced the early remission of post-LC abdominal distension, particularly for patients who had gallstones, cholecystic polyp, prolonged anesthesia or preoperative abdominal distention.

Prevalence and predictors of postcholecystectomy syndrome in Nepalese patients after 1 week of laparoscopic cholecystectomy: a cross-sectional study

Postcholecystectomy syndrome (PCS) is persistent distressing symptoms which develops following a laparoscopic cholecystectomy (LC); in cases when the condition is severe, readmission may be necessary. However, research on the prevalence of PCS and potential factors associated with PCS in Nepalese patients is still limited. An observational point-prevalence, correlational predictive cross-sectional study was conducted to determine the prevalence of PCS and examine what predicting factors including preoperative anxiety, preoperative dyspepsia, smoking, alcohol consumption, and duration of preoperative symptoms are associated with PCS. A total of 127 eligible Nepalese patients who came for follow-up after 1 week of LC at outpatient department of surgery in one single university hospital, Kathmandu, Nepal, were recruited. A set of questionnaires consisting participants' information record form, Hospital Anxiety and Depression Scale (HADS), Leeds Dyspepsia Questionnaires (LDQ), Fagerstrom Test for Nicotine Dependence (FTND), and Alcohol Use Disorder Identification Test (AUDIT) was administered for data collection. The associations between influential factors and PCS were analyzed using Binary logistic regression. 43.3% of participants reported PCS after 1 week of surgery. The findings from logistic regression analysis affirmed that the patients with preoperative anxiety (OR = 6.38, 95%CI = 2.07-19.67, p < 0.01) and moderate to severe dyspepsia (OR = 4.01, 95%CI = 1.34-12.02, p < 0.05) held the likelihood to report PCS 6.38 and 4.01 times, respectively, greater than others. The implications from study results are that screening of anxiety and patients' tailored interventions to reduce anxiety should be implemented preoperatively. An appropriate health education about persistence of PCS and self-management should be provided to those postoperative patients.

Demography, Spectrum, and Characteristics of Symptoms Associated With Post-operative Relief After Cholecystectomy

Background Cholecystectomy is one of the most commonly performed surgical procedures, and it is indicated for symptomatic gallstone disease. Symptoms of gallstone disease vary; many patients complain of the persistence of symptoms post-operatively. Hence, it is imperative to know the characteristics of symptoms that predict post-operative resolution. Methodology A prospective cross-sectional study was performed at a tertiary care centre. Patient demography and pre-operative symptoms were noted. Post-operative persistence or relief of symptoms was also documented. The occurrence of any new symptoms was noted. Data were collected at three and six months after surgery. Results Pain was the most common (85%) symptom. The mean frequency of pain was 2.45 per year (range 0-10). The mean duration of pain was 39.7 minutes (range 15-90 minutes). The right hypochondrium (39%) and the epigastric region (42%), along with 8% of patients who experienced pain in both places, were the most frequent locations of pain. The radiation of pain to the right-side scapula is present in 48% of patients. The pain persisted after one-week follow-up in 28 (34%) of patients, 26 (22%) at the end of one month, and 18 (21%) at the end of six months. Dyspepsia was unresolved in 25%, 20%, and 13% of individuals after one week, one month, and six months, respectively. Upper abdominal discomfort was still persistent in 29%, 26%, and 24% of study subjects at the time of follow-up periods, respectively. Similar persistence is found in symptoms of post-prandial fullness and nausea, where unresolved complaints of post-prandial fullness were present in 18%, 13%, and 10% of patients, respectively, and 26%, 14%, and 10% of patients complained of nausea. Conclusion The persistence of symptoms such as upper abdominal discomfort, dyspepsia, post-prandial fullness, and nausea is present, which gradually decreases in severity and presentation over the course of time after the surgical procedure. Some symptoms present after surgery, such as flatulence. Such persistent symptoms might lead to a decreased outcome in terms of patient satisfaction. Patients with atypical pain or dyspepsia need to be counselled pre-operatively regarding the poor resolution of such symptoms.

Do not get stumped: multimodality imaging findings of early and late post-cholecystectomy complications

Cholecystectomy is the most performed intra-abdominal surgical procedure in the US, with 1.2 million performed annually, and is predominantly performed laparoscopically. Although largely safe, laparoscopic cholecystectomy results in higher rates of abdominal symptoms consisting of abdominal pain and dyspepsia, which may persist or recur, collectively known as post-cholecystectomy syndrome. This article aims to (1) provide an overview of post-cholecystectomy syndrome with an emphasis on biliary complications and emergent imaging findings, (2) illustrate the spectrum of imaging findings of early and late post-cholecystectomy complications, (3) enumerate the role of various imaging modalities in evaluating post-cholecystectomy complications and address the role of selective trans-catheter coil embolization in managing bile leaks, and (4) discuss pearls and pitfalls in imaging following cholecystectomy. While common first-line imaging modalities for post-cholecystectomy complications include CT and sonography, ERCP and MRCP can delineate the biliary tree with greater detail. Scintigraphy has a higher sensitivity and specificity than CT or sonography for diagnosing bile leak and may preclude the need for ERCP. Post-operative complications include biliary duct injury or leak, biliary obstruction, remnant gallbladder/cystic duct stones and inflammation, biliary dyskinesia, papillary stenosis, and vascular injury. Subtle cases resulting in lethal outcomes, such as hemorrhage from the gallbladder bed without major vessel injury, have also been described. Cases presented will include biliary complications such as post-cholecystectomy stump cholecystitis, nonbiliary complications such as subcapsular hematoma, and normal post-surgical findings such as oxidized regenerated cellulose. Post-operative biliary complications can cause significant morbidity and mortality, and thus familiarity with the expected post-surgical appearance of the gallbladder fossa and biliary tract, as well as understanding the spectrum of complications and associated multimodality imaging findings, are essential for emergency radiologists and those practicing in the acute care setting to direct appropriate patient management. Furthermore, many of the postoperative complications can be managed by noninvasive percutaneous interventional procedures, from drain placement to cystic artery and cystic duct stump embolization.

Surgical management of cystic duct stump calculi causing post-cholecystectomy syndrome: A prospective study

Aim

Remnant cystic duct stump calculi are an uncommon but important cause of 'post-cholecystectomy syndrome'. High index of suspicion is needed to diagnose this condition in a symptomatic post-cholecystectomy patient. We present our experience with the surgical management of this condition.

Patients and Methods

This prospective study included 19 patients with residual gallstone disease who underwent completion cholecystectomy between August 2016 and October 2021. Investigations included abdominal ultrasound and magnetic resonance cholangiopancreatography. The demographic, clinical, surgical and early post-operative variables of these patients were prospectively maintained and analysed.

Results

The study included 14 women and 5 men. The mean age was 42.1 years (range, 14-80 years). The median duration between index surgery and completion cholecystectomy was 36 months (range, 2-178 months) (interquartile range, 105 months). The follow-up duration was 2 months. The initial surgery was open cholecystectomy in 17 and laparoscopic cholecystectomy in 2 patients. All patients with residual stump stone presented with pain, while 10 out of 19 patients complained of dyspepsia. Completion cholecystectomy could be performed laparoscopically in 16 cases, whereas 3 patients underwent open surgery. The mean operative time was 80 min (range, 55-140 min), and the mean blood loss was 100 ml (range, 50-160 ml). The mean hospital stay was 3 days (range, 2-10 days). No post-operative mortality or major morbidity was recorded in any of our patients.

Conclusion

Laparoscopic excision of the cystic duct stump is feasible and safe even after previous open cholecystectomy. It is increasingly becoming the treatment of choice where expertise is available.

Length of the Remnant Cystic Duct and Bile Duct Stone Recurrence: a Case‒Control Study

BACKGROUND

Since the introduction of the Critical View of Safety approach in laparoscopic cholecystectomy, exposure of the common bile duct, and common hepatic duct is not recommended, therefore, the length of the cystic duct remnant is no longer controlled. The aim of this case‒control study is to evaluate the relationship between the length of the cystic duct remnant and the risk for bile duct stone recurrence after cholecystectomy.

METHODS

All MRIs with dedicated sequences of the biliary tract taken between 2010 and 2020 from patients who underwent prior cholecystectomy were reviewed. The length of the cystic duct remnant was measured and compared between the patients with and without bile duct stones using multivariate logistic regression analysis.

RESULTS

A total of 362 patients were included in this study, 23.5% of whom had bile duct stones on MRI. The cystic duct remnant was significantly longer in the patients with stones than in the control group (median 31 mm versus 18 mm, P < 0.001). In the MRIs performed > 2 years after cholecystectomy, the cystic duct remnant was also significantly longer in the patients with bile duct stones (median 32 mm versus 21 mm, P < 0.001). A cystic duct remnant ≥ 15 mm in length increased the odds of stones (OR = 2.3, P = 0.001). Overall, the odds of bile duct stones increased with an increasing cystic duct remnant length (≥ 45 mm, OR = 5.0, P < 0.001).

CONCLUSIONS

An excessive cystic duct remnant length increases the odds of recurrent bile duct stones after cholecystectomy.

Síndrome post-colecistectomía: análisis de una cohorte prospectiva

Introducción. El síndrome post-colecistectomía fue descrito hace más de 70 años y se define como la presencia de síntomas gastrointestinales que pueden persistir después de la colecistectomía o aparecer como nuevos síntomas. Este síndrome, poco conocido, puede manifestarse desde pocos meses hasta varios años luego de la cirugía y ocurre entre 5 % y 40 % de los pacientes. Método. Estudio de cohorte prospectiva, que incluyó pacientes a quienes se les realizó colecistectomía laparoscópica en tres unidades quirúrgicas de Bogotá, D.C., Colombia, durante un período de ocho meses, con seguimientos periódicos durante dos años. El síndrome post-colecistectomía se definió como la presencia de al menos un síntoma gastrointestinal a partir del primer mes de la cirugía. Resultados. Se incluyeron 380 pacientes de los cuales 183 (48,2 %) desarrollaron el síndrome. La edad tuvo diferencia estadísticamente significativa entre aquellos que lo desarrollaron y los que no (p=0,024). La diarrea fue el único síntoma preoperatorio asociado al desarrollo del síndrome. El síndrome post-colecistectomía se encontró en el 42,1 % de los pacientes al primer mes de seguimiento y en el 17,4 % al segundo año. Conclusiones. El síndrome post-colecistectomía ocurre en un porcentaje importante de pacientes. En concordancia con la literatura, se encontró que la diarrea prequirúrgica es un factor de riesgo independiente para el desarrollo del síndrome. Se recomienda un adecuado seguimiento de los pacientes después de una colecistectomía.

Prevalence and Factors Associated With Post-Cholecystectomy Syndrome in Saudi Arabia

OBJECTIVES

Post-cholecystectomy syndrome (PCS) refers to the continuation or recurrence of biliary colic and any other gastrointestinal symptoms present prior to cholecystectomy. Given that PCS is rare and underestimated in Saudi Arabia, this study aimed to determine the prevalence of PCS among Saudis.

METHODS

This cross-sectional study included randomly gathered subjects who self-administered the validated European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire from September 6 to October 7, 2022.

RESULTS

A total of 518 participants who underwent cholecystectomies were included; most were female (73.6%), 153 (29.5%) were 19 to 25 years old, and the vast majority were Saudi Arabian (91.1%). The average preoperative weight was 71 ± 20.7 kg (range 20 to 258), and the mean current weight was 69 ± 19.4 kg (range 30 to 257). About 137 (26.4%) had a chronic disease, most frequently hypertension (37.2%). In the past week, most participants experienced some trouble doing strenuous activities (42.9%), slight pain (37.6%), fatigue (32.2%), insomnia (37.5%), and weakness (38.2%). There were no significant associations between age, nationality, or residence with the QLQ-C30 score (P-value = 0.152, 0.262, 0.071, respectively). A significant association was observed between gender and QLQ-C30 score (P-value < 0.001), with females scoring higher than their male counterparts. Females also reported having a higher quality of life than males.

CONCLUSIONS

The prevalence of PCS was higher than reported elsewhere.

Post-cholecystectomy syndrome: A cohort study from a single private tertiary center

Objectives

Although post-cholecystectomy syndrome (PCS) is a well-recognized complication, there are few reports arising from KSA. The effect of sleeve gastrectomy or endoscopic retrograde cholangiopancreatography (ERCP) stenting on the development of PCS is unknown. We aimed to measure the possible factors affecting the development of PCS, such as symptom duration, comorbidities, previous bariatric surgery, ERCP stent insertion, surgical intervention, conversion to open surgery and complication rate.

Methods

This was a prospective cohort and observational study conducted at a single, private tertiary center. We included 167 patients who underwent surgery for gallbladder disease between October 2019 and June 2020. The patients were classified into two groups according to their PCS status (PCS+ vs. PCS-).

Results

Thirty-nine patients were PCS+ (23.3%). There was no significant difference between the two groups with regards to age, gender, BMI, ASA score, smoking, comorbidities, duration of symptoms, previous bariatric surgery, ERCP, stent insertion or sphincterotomy. Chronic cholecystitis was the predominant histopathology in 83% (139/167) of patients. The most frequent causes of PCS included biliary system dysfunction, bile salt-induced diarrhea, gastritis, gastroesophageal reflux disease, and retained stones. Overall, 71.8% (28/39) of patients had incident PCS; the remaining patients had persistent PCS.

Conclusions

PCS is a neglected complication that was observed in 25% of patients mainly in the first year. Surgeon awareness can assist with patient diagnosis, preoperative selection and education. Furthermore, the history of ERCP stenting, sphincterotomy, or sleeve gastrectomy seems to be unrelated to PCS development.

Cholecystectomy for asymptomatic gallstones: Markov decision tree analysis

Gallstones are a common public health problem, especially in developed countries. There are an increasing number of patients who are diagnosed with gallstones due to increasing awareness and liberal use of imaging, with 22.6%-80% of gallstone patients being asymptomatic at the time of diagnosis. Despite being asymptomatic, this group of patients are still at life-long risk of developing symptoms and complications such as acute cholangitis and acute biliary pancreatitis. Hence, while early prophylactic cholecystectomy may have some benefits in selected groups of patients, the current standard practice is to recommend cholecystectomy only after symptoms or complications occur. After reviewing the current evidence about the natural course of asymptomatic gallstones, complications of cholecystectomy, quality of life outcomes, and economic outcomes, we recommend that the option of cholecystectomy should be discussed with all asymptomatic gallstone patients. Disclosure of material information is essential for patients to make an informed choice for prophylactic cholecystectomy. It is for the patient to decide on watchful waiting or prophylactic cholecystectomy, and not for the medical community to make a blanket policy of watchful waiting for asymptomatic gallstone patients. For patients with high-risk profiles, it is clinically justifiable to advocate cholecystectomy to minimize the likelihood of morbidity due to complications.

It's time for a minimum synoptic operation template in patients undergoing laparoscopic cholecystectomy: a systematic review

BACKGROUND

Despite the call to enhance accuracy and value of operation records few international recommended minimal standards for operative notes documentation have been described. This study undertook a systematic review of existing operative reporting systems for laparoscopic cholecystectomy (LC) to fashion a comprehensive, synoptic operative reporting template for the future.

METHODS

A search for all relevant articles was conducted using PubMed version of Medline, Scopus and Web of Science databases in June 2021, for publications from January 1st 2011 to October 25th 2021, using the keywords: laparoscopic cholecystectomy AND operation notes OR operative notes OR proforma OR documentation OR report OR narrative OR audio-visual OR synoptic OR digital. Two reviewers (NOC, GMC) independently assessed each published study using a MINORS score of ≥ 16 for comparative and ≥ 10 for non-comparative for inclusion. This systematic review followed PRISMA guidelines and was registered with PROSPERO. Synoptic operative templates from published data were assimilated into one "ideal" laparoscopic operative report template following international input from the World Society of Emergency Surgery board.

RESULTS

A total of 3567 articles were reviewed. Following MINORS grading 25 studies were selected spanning 14 countries and 4 continents. Twenty-two studies were prospective. A holistic overview of the operative procedure documentation was reported in 6/25 studies and a further 19 papers dealt with selective surgical aspects of LC. A unique synoptic LC operative reporting template was developed and translated into Chinese/Mandarin, French and Arabic.

CONCLUSION

This systematic review identified a paucity of publications dealing with operative reporting of LC. The proposed new template may be integrated digitally with hospitals' medical systems and include additional narrative text and audio-visual data. The template may help define new OR (operating room) recording standards and impact on care for patients undergoing LC.

Global Prevalence and Impact of Rumination Syndrome

BACKGROUND & AIMS

Rumination syndrome is a Disorder of Gut-Brain Interaction (DGBI) of unknown etiology. We aimed to assess its global prevalence and potential associations with other medical conditions.

METHODS

Data were collected via the Internet in 26 countries. Subjects were evenly distributed by country, sex, and age groups and were invited for a "health survey" using the Rome IV diagnostic questionnaire and a supplementary questionnaire addressing factors potentially associated with DGBI.

RESULTS

In all, 54,127 subjects completed the survey (51% male; mean age, 44.3 years). The overall prevalence of rumination syndrome was 3.1% (95% confidence interval [CI], 3.0-3.3%). It was highest in Brazil (5.5% CI, 4.5-6.5) and lowest in Singapore (1.7% CI, 1.1-2.2). The mean age of people with rumination syndrome was 44.5 years (standard deviation, 15.6) and it was more common in females (54.5% vs 45.5%). Factors independently associated with rumination syndrome were depression (odds ratio [OR], 1.46), anxiety (OR, 1.8), body mass index (OR, 1.04), and female sex (OR, 1.19). Subjects with multiple DGBI were at increased risk of having rumination syndrome, with the highest risk in subjects with 4 gastrointestinal regions with DGBI (OR, 15.9 compared with none). Quality of life (QoL) was lower in subjects with rumination syndrome compared with the rest of the cohort (PROMIS-10 score: physical QoL mean 12.9 vs 14.5; mental QoL mean 12.0 vs 13.6).

CONCLUSIONS

The prevalence of rumination syndrome is higher than reported in most previous population studies and is likely underdiagnosed in clinical practice. Awareness of rumination syndrome should be raised among clinicians to improve care for these patients.

Dyspepsia and Gut Microbiota in Female Patients with Postcholecystectomy Syndrome

BACKGROUND

Gallstone disease (GSD) represents one of the most frequent digestive disorders, highly reported in female gender. The purpose of the study was to explore the clinical and gut microbiota particularities of female patients with postcholecystectomy syndrome (PCS) and the possible relationship between gut dysbiosis (DB) and abdominal complaints.

PATIENTS AND METHODS

In total, 129 female participants: 104 outpatients divided into two equal groups, 52 PCS (+), 52 PCS (-) and 25 healthy controls were consecutively enrolled in this observational study. Patients underwent clinical examination with assessment of pain, bloating, transit disturbances, abdominal ultrasound/computer tomography/magnetic resonance imaging/endoscopic retrograde cholangiopancreatography, upper and lower digestive endoscopies. Laboratory work-ups and stool microbiology assessments were performed for all study participants (patients and controls). Stool microorganisms were identified by matrix-assisted laser desorption ionization - time-of-flight- mass spectrometry and in patients with DB also by next-generation sequencing.

RESULTS

Older age, complicated gallstones disease, associated conditions like diabetes mellitus/impaired glucose tolerance and irritable bowel syndrome were significantly present in PCS (+) group, as well as sedentary lifestyle and diets characterized by a low fiber intake (p<0.0001). PCS (+) patients displayed significant differences related to the incidence and severity of overall gut microbiota DB, decreased H index of biodiversity and the unbalanced Firmicutes/Bacteroidetes (F/B) ratios by comparison to the PCS (-) group (p<0.0001). Strong positive correlations of the severity of overall DB with bloating and the intestinal habit disorders, as well as of F/B ratios to all abdominal symptoms were noted.

CONCLUSION

PCS in female patients was associated with older age, sedentary lifestyle, specific dietary habits, history of complicated gallstone disease, diabetes mellitus/impaired glucose tolerance and irritable bowel syndrome, as well as gut microbiota particularities. Overall DB and unbalanced F/B ratios were strongly correlated to abdominal complaints.

Improvement of the algorithm for diagnostics of postcholecystectomy syndrome taking into account functional and organic changes in the area of the large duodenal nipple

The aim. Improving the algorithm for diagnosing patients with postcholecystectomy syndrome (PCS), taking into account functional and organic changes in the major duodenal papilla (MDP). Materials and methods. 208 patients with PCS were examined. Laparoscopic cholecystectomy (CE) was performed in 172 patients in history, open CE was performed in 36 patients. 47 patients had obstructive jaundice, 84 had signs of biliary hypertension without an increase in bilirubin, 77 had no signs of biliary hypertension and an increase in bilirubin. The following instrumental research methods were used: abdominal organs ultrasound examination (AO USE), duodenoscopy, endoscopic retrograde cholangiopancreatography (ERCP), computed tomography (CT). In the main group, to study the morphofunctional changes in MDP, duodenoscopy with parietal impedancemetry, ultrasound of the hepatobiliary zone with a choleretic load were used. Results. In the main group, 34 patients underwent ultrasound of the hepatobiliary zone and Vater's nipple area with a choleretic breakfast according to Boyden according to the method of Grigoriev P.Ya. in our modification, 21 patients had an expansion of the choledochus by 2 mm. At the same time, taking meverin led to a decrease in the diameter of the choledochus, which indicated functional changes in the MDP. In 13 patients, the expansion of the choledochus, observed when taking a choleretic breakfast, persisted with the use of antispasmodics, which indicated the presence of an organic pathology of MDP. Duodenoscopy with impedancemetry was performed in 41 patients: 20 patients had 760–820 Ohm, which indicated the presence of functional changes, 12 patients had inflammatory changes in the MDP and 703–760 Ohm were detected, 9 patients with cicatricial fibrous changes had indicators impedance measurement 640–703 Ohm. The use of ultrasound with a choleretic breakfast and duodenoscopy with parietal impedancemetry in patients of the main group made it possible to identify functional and organic (inflammatory, fibrous) changes in the MDP, which made it possible to develop a therapeutic algorithm using both conservative therapy and the use of various options for transpapillary endoscopic interventions. Conclusions. Conducting an in-depth diagnosis of morpho-functional changes in MDP using parietal impedancemetry of MDP and ultrasound of the hepatobiliary zone with choleretic load allows us to identify both functional and morphological changes in MDP, which makes it possible to develop a therapeutic algorithm using drug therapy and transpapillary endoscopic techniques.

Risk Factors for Early Recurrence of Gallstones in Patients Undergoing Laparoscopy Combined With Choledochoscopic Lithotomy: A Single-Center Prospective Study

Objective: For patients with gallstones, laparoscopy combined with choledochoscopic lithotomy is a therapeutic surgical option for preservation rather than the removal of the gallbladder. However, postoperative recurrence of gallstones is a key concern for both patients and surgeons. This prospective study was performed to investigate the risk factors for early postoperative recurrence of gallstones.

Methods: The clinical data of 466 patients were collected. Each patient was followed up for up to 2 years. The first follow-up visit occurred 4 months after the operation, and a follow-up visit was carried out every 6 months thereafter. The main goal of each visit was to confirm the presence or absence of gallbladder stones. The factors associated with gallstone recurrence were analyzed by univariate analysis and Cox regression.

Results: In total, 466 eligible patients were included in the study, and 438 patients (180 men and 258 women) completed the 2-year postoperative follow-up. The follow-up rate was 94.0%. Recurrence of gallstones was detected in 5.71% (25/438) of the patients. Univariate analysis revealed five risk factors for the recurrence of gallstones. Multivariate Cox regression analysis showed that multiple gallstones, a gallbladder wall thickness of ≥4 mm, and a family history of gallbladder stones were the three predictive factors for postoperative recurrence of gallstones (P < 0.05).

Conclusion: The overall 2-year recurrence rate of gallstones after the operation was 5.71%. Multiple gallstones, a gallbladder wall thickness of ≥4 mm, and a family history of gallstones were the three risk factors associated with early postoperative recurrence of gallstones.

Laparoscopic remnant cholecystectomy for calculi in the remnant gallbladder following subtotal-cholecystectomy: a report of two cases

Two cases of laparoscopic remnant cholecystectomy using near-infrared fluorescence cholangiography (NIFC) for remnant gallbladder calculi following subtotal-cholecystectomy are reported. Case 1: a 36-year-old woman was referred to our hospital with acute abdomen. Computed tomography showed remnant gallbladder calculi, with detected no other findings as the cause of the abdominal pain. For intraoperative exploration of the biliary anatomy, 0.25 mg/kg of indocyanine green (ICG) was administered intravenously the day before the operation. NIFC clearly showed the common bile duct and enabled safe laparoscopic remnant cholecystectomy. She was free from symptoms after the operation. Case 2: a 40-year-old woman was referred to our hospital with epigastralgia due to remnant gallbladder calculi after open cholecystectomy. ICG was administered intravenously the day before the operation. Severe adhesions were observed in the upper abdominal cavity and there was tight adherence of the duodenum to the remnant gallbladder. NIFC showed a clear margin that appeared to be the margin between the duodenum and remnant gallbladder. However, dissection of the margin observed by NIFC caused perforation of the duodenum. The clear margin seen with NIFC was likely due to visualization of the gallbladder through the duodenum. Although NIFC is a useful modality for confirming the intraoperative biliary anatomy, it is important not to rely too heavily on NIFC alone, which may lead to misinterpretation of the anatomy.

Post-cholecystectomy syndrome: a retrospective study analysing the associated demographics, aetiology, and healthcare utilization

Background

Post-cholecystectomy syndrome (PCS) is a group of heterogeneous signs and symptoms, predominately consisting of right upper quadrant abdominal pain, dyspepsia, and/or jaundice, manifesting after undergoing a cholecystectomy. According to some studies, as many as 40% of post-cholecystectomy patients are in fact, affected by this syndrome. This study aims to determine the demographics, aetiology, average length of hospital stay, and health care burden associated with PCS.

Methods

We queried the National Inpatient Sample (NIS) database to determine inpatient admissions of PCS between 2011 and 2014 using the ICD-9 primary diagnosis code 576.0.

Results

From 2011 to 2014, the number of inpatient admissions with a principal diagnosis of PCS totally 275. The average length of hospital stay was 4.28±4.28, 3.42±2.73, 3.74±1.84, and 3.79±2.78 days in 2011, 2012, 2013, and 2014, respectively. The total yearly charges were $32,079±$24,697, $27,019±$22,633, $34,898.21±$24,408, and $35,204±$32,951 in 2011, 2012, 2013, and 2014, respectively. Notably, the primary cause of PCS in our patient sample between the year 2011 and 2014, was biliary duct dysfunction, followed by Peptic ulcer disease.

Conclusions

In conclusion, there is a strong need to examine for and treat the underlying aetiology when approaching a post-cholecystectomy patient. We found that longer hospital stays, were associated with a greater health care burden, and visa versa. Furthermore, our findings help identify at-risk populations which can contribute to improving surveillance of this costly disease.

MRI evaluation of bile duct injuries and other post-cholecystectomy complications

Laparoscopic cholecystectomy is one of the most common procedures performed each year and can be associated with various post-operative complications. Imaging is integral to diagnosis and management of patients with suspected cholecystectomy complications, and a thorough understanding of normal and abnormal biliary anatomy, risk factors for biliary injury, and the spectrum of adverse events is crucial for interpretation of imaging studies. Magnetic resonance cholangiography (MRC) enhanced with hepatobiliary contrast agent is useful in delineating biliary anatomy and pathology following cholecystectomy. In this article, we provide a protocol for contrast-enhanced MR imaging of the biliary tree. We also review the classification and imaging manifestations of post-cholecystectomy bile duct injuries in addition to other complications such as bilomas, retained/dropped gallstones, and vascular injuries.

The Impact of Cholecystectomy on Long-Term Disease Outcomes and Quality of Life in Patients with Crohn's Disease

BACKGROUND

Cholecystectomy (CCY) is one of the most frequently performed abdominal surgeries. However, the impact of CCY in clinical settings with altered gastrointestinal physiology and anatomy, such as Crohn's disease (CD), has not been fully characterized. We sought to investigate clinical outcomes, disease severity, and quality of life of CD patients after CCY.

METHODS

We utilized a prospective, longitudinal registry of consented CD patients followed at a tertiary center. Crohn's disease patients that had or had not undergone CCY formed the 2 study groups. The absence or presence of gallbladder was confirmed with abdominal CT scans obtained during routine care. Multiyear clinical, biochemical, and histologic data were collected and analyzed.

RESULTS

Among 834 CD patients, 151 (18%) had undergone CCY. History of CCY was associated with higher disease activity (median Harvey-Bradshaw index; P < 0.001), more years with anemia (P = 0.048), lower albumin (P = 0.001), worse quality of life (mean Short Inflammatory Bowel Disease Questionnaire; P < 0.001), chronic abdominal pain (P < 0.001), higher risk for incident colonic dysplasia (P = 0.011), higher rates of annual hospital admissions (P = 0.004), and opioid use (P < 0.001). In multivariate analysis, CCY remained associated with higher disease activity (P < 0.001), lower albumin (P = 0.008), lower quality of life (P < 0.001), and more hospital admissions (P = 0.008), whereas CD patients with diseased ileum had higher risk for colonic dysplasia (P = 0.031).

CONCLUSIONS

CCY in CD patients was associated with multiple markers of disease activity and worse quality of life during multiyear follow up. This data suggests that CCY in CD patients may adversely impact the long-term clinical course.

Factors related to residual gallbladder calculi formation using computed tomography and magnetic resonance imaging combined with clinical data

Objective

We aimed to investigate risk factors related to remnant gallbladder (RGB) stones.

Methods

This retrospective study included 73 patients with RGB, in groups with and without RGB calculi. Univariate analyses were used to identify nine variables associated with RGB calculi: sex, age, body mass index (BMI), time to detection, surgical method, length of RGB, angle of RGB and common hepatic duct (CHD), choledocholithiasis, and remnant cholecystitis. Multivariate logistic regression was performed to assess independent predictors of RGB stones. A receiver operating characteristic (ROC) curve was used to estimate model accuracy and determine cut-off values of independent predictors.

Results

We enrolled 73 patients, 33 with and 40 without RGB stones. Univariate analyses showed that age, BMI, time to detection, length of RGB, angle of RGB and CHD were predictors for RGB calculi. Multivariate analyses indicated that time to detection, length of RGB, and angle of RGB and CHD were independent predictors for RGB calculi. The area under the ROC curve of the model was 0.940. Cut-off values of the three indicators were 1.5 years, 2.25 cm, and 22.5°, respectively.

Conclusion

Time to detection, length of RGB, and angle of RGB and CHD were independent predictors of RGB calculi.

Acupuncture for the Postcholecystectomy Syndrome: A Systematic Review and Meta-Analysis

Background

Postcholecystectomy syndrome (PCS) has become a common postoperative syndrome that requires systematic and comprehensive therapy to achieve adequate clinical control. Acupuncture and related therapies have shown clinical effects for PCS in many studies. However, systematic reviews/meta-analyses (SRs/MAs) for them are lacking.

Objective

To evaluate the efficacy and safety of acupuncture in the treatment of PCS using randomized controlled trials (RCTs).

Methods

Potentially eligible studies were searched in the following electronic databases up to 1 February 2020: PubMed, Embase, Cochrane Library, Web of Science (WoS), Chinese databases (Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), WanFang Database (WF), and China Science and Technology Journal Database (VIP)), and other sources (WHO ICTRP, ChiCTR, Clinical Trials, and Grey Literature Database). The RevMan 5.3 was employed for analyses. The Cochrane Collaboration' risk of bias tool was used to assess the risk of bias (ROB). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of the evidence.

Results

A total of 14 RCTs with 1593 participants were included in this SR. MA showed that acupuncture in combination with conventional medicine (CM) did not show statistical differences in reduction in pain. However, acupuncture in combination with CM significantly reduced the incidence of postoperative nausea and vomiting (PONV) (RR, 0.71; 95% CI, 0.55–0.92) and improved gastrointestinal function recovery compared to the CM group. Acupuncture combined with traditional Chinese medicine and CM, and acupuncture as monotherapy may improve gastrointestinal function recovery with acceptable adverse events.

Conclusion

Acupuncture may be an effective and safe treatment for PCS. However, this study lacks conclusive evidence due to poor quality evidence, limited data, and clinical heterogeneity of acupuncture methods in the included studies.

Increased Risk of Acute Pancreatitis with Codeine Use in Patients with a History of Cholecystectomy

BACKGROUND

Codeine has a spasmodic effect on sphincter of Oddi and is suspected to cause acute pancreatitis in patients with a history of cholecystectomy.

AIMS

To assess the association between codeine use and acute pancreatitis in patients with a previous cholecystectomy.

METHODS

We conducted a retrospective nested case-control study using the 2005-2015 MarketScan^® Commercial Claims and Encounters Database. The cohort included patients aged 18-64; cohort entry began 365 days after cholecystectomy. Odds ratios (ORs) and 95% CIs for acute pancreatitis hospitalization were estimated comparing use of codeine with non-use of codeine. In a secondary analysis, use of codeine was compared with an active comparator: use of non-steroidal anti-inflammatory drugs (NSAIDs).

RESULTS

Of the 664,083 patients included in the cohort, 1707 patients were hospitalized for acute pancreatitis (incidence 1.1 per 1000 person-years) and were matched to 17,063 controls. Compared with non-use of codeine, use of codeine was associated with an increased risk of acute pancreatitis (OR 2.67; 95% CI 1.63, 4.36), particularly elevated in the first 15 days of codeine use (OR 5.37; 95% CI 2.70, 10.68). Compared with use of NSAIDs, use of codeine was also associated with an increased risk of acute pancreatitis (OR 2.64; 95% CI 1.54, 4.52).

CONCLUSION

Codeine is associated with an increased risk of acute pancreatitis in patients who have previously undergone cholecystectomy; greater clinician awareness of this association is needed.

Late postcholecystectomy Mirizzi syndrome due to a sessile gall bladder remnant calculus managed by laparoscopic completion cholecystectomy: a feasible surgical option

Postcholecystectomy Mirizzi syndrome (PCMS) is an uncommon entity that can occur due to cystic duct stump calculus, gall bladder remnant calculus or migrated surgical clip. It can be classified into early PCMS or late PCMS. It is often misdiagnosed and the management depends on the site of impaction of stone or clip. Endoscopy can be performed for cystic duct stump calculus. However, surgery is the treatment for remnant gall bladder calculus. Role of laparoscopic management is controversial. We present here a case of a 48-year-old woman with late PCMS due to an impacted calculus in a sessile gall bladder remnant following a subtotal cholecystectomy, managed with laparoscopic completion cholecystectomy, review the literature, provide tips for safe laparoscopy for PCMS and summarise our algorithmic approach to the management of the postcholecystectomy syndrome.

Acupuncture for the postcholecystectomy syndrome: Protocol for a systematic review and meta-analysis

BACKGROUND

Postcholecystectomy syndrome (PCS) is a term used to describe the persistence of biliary colic or right upper quadrant abdominal pain with a variety of postoperative gastrointestinal symptoms. Acupuncture and related treatments have shown clinical effects for PCS in many studies. But the systematic reviews and meta-analyses for them are lacking. We aim to evaluate the efficacy and safety of acupuncture on the treatment of PCS.

METHODS

We will search 8 electronic databases, including the Web of Science, PubMed, Cochrane Library, Embase, and 4 Chinese databases (CBM, Wanfang, VIP, and CNKI databases), and additional sources (WHO ICTRP, ChiCTR, Clinical Trials, Grey Literature Database), for potentially eligible studies. Literature retrieval, screening, and data extraction will be conducted by 2 researchers independently. In case of disagreement, a 3rd party shall be consulted to assist judgment. We will use RevmanV.5.3 to perform a fixed effect meta-analysis on the data of clinical homogeneity studies, and evidence's level will be assessed through the method for GRADE.

RESULTS

This systematic review and meta-analysis will put a high-quality synthesis of the efficacy and safety of acupuncture treatment in PCS.

CONCLUSION

The conclusion of this systematic review will provide evidence to assess acupuncture therapy is an efficacy and safe intervention to treat and control PCS.
