ROLE OF PRE-OPERATIVE UPPER GASTRO-INTESTINAL ENDOSCOPY IN SYMPTOMATIC PATIENTS UNDERGOING ELECTIVE LAPAROSCOPIC CHOLECYSTECTOMY FOR GALL BLADDER STONE DISEASE.

BACKGROUND

Gallbladder stone disease is one of the most common problems encountered in surgical practice. Gallbladder calculi constitute a significant health problem in developed countries, affecting 10% to 15% of the adult population [1]. In Asia, the prevalence of gallstone disease is 5-10% of population especially among older individuals and females. The number of surgeries for Gallbladder stone disease has risen markedly in developed countries since 1950. The introduction of laparoscopic cholecystectomy in 1989 further increased the cholecystectomy rate. [1]

The diagnosis of gallbladder stone disease has steadily increased because of the common access to sonography. The vast majority of cholecystectomies are performed for gallbladder calculi with cholesterol stones accounting for nearly 75% of all gallstones. [2]

Gallstones are common the majority will be asymptomatic: up to 80% will never experience biliary colic or complications such as acute cholecystitis, cholangitis, or pancreatitis. [3] Hence, most gallbladder calculi are clinically "silent" an incidental finding often uncovered during abdominal sonography being performed for another reason. Since most gallbladder calculi are asymptomatic, it is essential to define exactly which symptoms are caused by gallbladder calculi: true biliary colic and/or complications, versus vague abdominal complaints including dyspeptic symptoms. The importance for clarifying what constitutes true biliary colic is to better predict relief following surgery.

Cholecystectomy proved successful in treating the patients of biliary colic and cholecystitis in 80-95% of patients with calculi. When calculi were not present, the presence of symptoms was as high as 40%. [4] The persistence of abdominal symptoms even after cholecystectomy is highly discouraging for surgeons. Coexistence of concurrent upper gastrointestinal problems in gallbladder calculi patients may have attributed to the post cholecystectomy syndrome. [5]

Post-cholecystectomy syndrome (PCS) consists of a group of upper gastro-intestinal symptoms that recur and/or persist. After cholecystectomy. It is defined. as early if occurring in the post-operative period and late if it manifests after months or years. Although this term. Is used widely, it is not completely accurate as it includes a large number of disorders, both biliary and extra-biliary in origin, that may be unrelated to surgery for cholelithiasis. [6]

To identify the cause of right upper abdominal pain, oesophagogastroduodenoscopy (Upper GI endoscopy) is important to identify the diseases of upper gastrointestinal tract. As it evaluates the mucosa for signs of disease from the esophagus through the duodenum & allows direct visualization of the ampulla Of Vater. [7]

These upper gastrointestinal symptoms have been. related to gallbladder calculi but causal relationship has not been established yet. Evaluation of gall stone disease is an immense challenge as to ascertain whether gallstones are responsible for symptoms or just an incidental finding and acid peptic disease of the stomach or the duodenum, reflux disease or hiatus hernia may be the true cause of pain.

Thus, this study tries to seek the importance of upper gastro intestinal endoscopy to reveal the association between gastrointestinal symptoms and diseases with gallbladder calculi to establish a plan of treatment which is one of the most common problems faced by the current surgeon, for the complete cure of all patients.

METHODS

This is a hospital based one year, observational, cross-sectional, hospital based, study conducted in KLES Dr. Prabhakar Kore Hospital. The study was conducted between January 2017 to December 2017.

Source of Data

All symptomatic patients getting admitted to the surgery wards, in KLES Dr. Prabhakar Kore Hospital with ultrasonographically proven Gall Bladder Stone Disease, who merit surgery.

Inclusion Criteria

All symptomatic patients having GB stone disease proven by ultrasonography who merit surgery.

Exclusion Criteria

* Acute abdomen.

* CBD stones.

* Obstructive jaundice.

* Cholangitis.

* GB stone pancreatitis.

* GB neoplasm.

* Previous GB or pancreatic surgery.

Rationale for Sample Size

A study carried out by Mohamed Toum Musa M Ibrahim [8] et al has observed that the pathological findings with upper GI endoscopy for all those diagnosed with Gall bladder stone disease was 60%.

In our study expecting similar results with 95% confidence levels and 20% of relative precision in the result, the study requires a minimum of 66 subjects.

n= (Za)A2[pXq]/d^2

n= 2^2[60X40]/12^2

n= 9600/144

n= 66.

This prospective study was conducted on the patients meeting the inclusion criteria, for patients attending the general surgery OPD at KLES Dr. Prabhakar Kore Hospital.

After clinical assessment, and ultrasonography, patients will be admitted and subjected to UGI scopy and a biopsy would be taken if necessary.

Institutional approval was taken for the study. Verbal and written informed consent were taken from each participant. The data collected from the patients includes personal information, presenting symptoms--typical (Biliary colic)/atypical (Vague upper abdominal symptoms), investigations including ultrasonography, Upper GI endoscopy findings biopsy reports if present.

UGE was performed in the endoscopy room 1-2. days prior to operation. The presence of ulcer and inflammation of gastric mucous membrane will be subjected to histopathological examination. The clinical symptoms will be categorized as typical or atypical based on the characters mentioned above. The endoscopic findings were divided as normal, inflammatory, erosions, ulcers and others including carcinomas. Similar categorizations were applied for histopathological findings as well.

Statistical Analysis

The statistical analysis will be performed using SPSS version 22. The findings of the study were cross tabulated using the SPSS 22 software and was analyzed using the Chi square test to obtain the p value, and the association was considered significant if the p-value between the two variables was <0.05.

RESULTS

A total of 66 patients were included in the study from January 2017 to December 2017, their ages ranged from 16 to 81 years with a mean age of 45.8 +/- 16.5. There was a total of 28 males and 38 females in the study.

The subject's symptomatology was divided into, Typical biliary colic, which is constant and increases in severity over the first half hour or so and typically lasts 1 to 5 hours. It is located in the epigastrium or right upper abdomen and frequently radiates to the right upper back or between the scapulae, and Atypical biliary symptoms, here the pain may be located primarily in the back or the left upper or lower right quadrant. Out of the 66 subjects 30 had typical symptoms and 36 had atypical symptoms.

DISCUSSION

Upper gastro intestinal endoscopy has been recommended pre operatively in patients undergoing elective laparoscopic cholecystectomy for gall bladder stone disease by Thybusch et al., [9] Sosada et al. [10] and many others to diagnose the coexistent UGI lesions in these patients, which otherwise went unnoticed and led to persistence of the patient's symptoms post-surgery.

A total of 66 patients were included in the study, the age of the patients ranged from 16-81 years, and most of the patients belonged to the 46-60 age group, the mean age of the patients was 45.8 years, which is comparable to other studies (40.6). [11]

Among the 66 study subjects 36.4% (n=24), were found to have positive UGI scopy findings, out of which 29.2% (n=7) had typical biliary colic and 70.8% (n=17) had atypical biliary symptoms.

In comparison with this 63.6% (n=42) of the study subjects had normal UGI scopy findings, out of which 54.8% (n=23) had typical biliary colic and 45.2% (n=19) had atypical biliary colic.

Inferring that the chances of yielding a positive UGI scopy is higher in patients with atypical biliary symptoms.

Female preponderance was noted in the study with 57.6% (n=38) females and 42.4% (n=28) males, with a male to female ratio of 1:1.3, which is strongly supported by many studies. Rashid et al. [12] also published similar results with male to female ratio 1:4.

This study has shown that majority of the patients 54.5% (n=36) presented with atypical biliary symptoms, as compared to patients who presented with typical biliary colic, (45.5%, n=30).

This study found that 36.4% (n=24) of the study subjects had positive UGI-scopy findings, which is statistically significant with a p value of 0.045.

This result is supported by

* Study performed by Diettrich et al. [13] also suggested 31/100 patients had abnormalities on UGI-SCOPY.

* Schwenk et al. [14] suggested that 30.2% (345 patients) had pathological findings.

* Rassek et al. [15] recommends that investigation of the upper gastrointestinal tract must precede an elective cholecystectomy, as his study showed that 44% of patients had positive UGI-SCOPY findings.

It has been observed from this study that the prevalence of typical biliary colic is higher among the young (16-30 years) as compared to atypical symptoms i.e., 73.3% and 26.7% respectively, while on the other hand atypical biliary symptoms is more common in the older age group (61-75 years) than typical biliary colic i.e. 69.2% and 30.8% respectively.

Among the 66 study subjects, 39.5% and 60.5% of the females had typical and atypical biliary symptoms respectively, whereas 53.5% and 46.5% of males had typical and atypical symptoms respectively. But the sex wise distribution of symptoms was almost equal and not statistically significant with a p value of 0.256.

Among the 66 study subjects 36.4% (n=24), were found to have positive UGI scopy findings, out of which 29.2% (n=7) had typical biliary colic and 70.8% (n=17) had atypical biliary symptoms. In comparison with this 63.6% (n=42) of the study subjects had normal UGI scopy findings, out of which 54.8% (n=23) had typical biliary colic and 45.2% (n=19) had atypical biliary colic. Inferring that the chances of yielding a positive UGI scopy is higher in patients with atypical biliary symptoms. In a similar study by Mohamad Mozafar and his colleague's et al. [16] they found that, among the 178 patients with atypical pain, 148 (83%) had abnormal findings in UGIScopy.

In another study Faisal et. al. [17] concluded that 77.2% of their patients with typical symptoms had positive UGI-Scopy findings.

Karmacharya A et al [18] have observed that normal UGI findings are seen in patients with typical pain reinforcing the fact that patients with typical abdominal pain has less likelihood of presenting with coexisting upper gastrointestinal lesion as evidenced in other studies.

Sosada et al. [10] observed in his study gastric ulcer in 179 (6.4%), duodenal ulcer in 127 (4.5%), gastritis in 375 (26.3%), polyps in 143 (5.1%) and cancer in 3 (.1%) patients. Similarly in this study UGI-scopy showed lax cardia and fundal gastritis in 7 (10.6%), chronic diffuse erosive gastritis in 1 (1.5%), lax cardia and grade b esophagitis in 5 (7.8%), scattered gastric erosions in fundus and antrum in 2 (3.0%), periampullary diverticulum in second part of duodenum in 1 (1.5%), lax cardia with fundal gastritis and grade a esophagitis in 3 (4.5%), diffuse chronic gastritis in 2 (3.0%), lax cardia with bile reflux esophagitis and duodenitis in 1 (1.5%), lax cardia and hiatus hernia in 1 (1.5%), bile reflux gastritis in 1 (1.5%).

CONCLUSIONS

Increased access to ultrasound for patients presenting with pain abdomen, has led to an increase in the diagnosis of cholelithiasis, as its symptomatology overlaps many upper GI lesions, the incidental finding of gall stones on ultrasound may mask the co-existing UGI lesions.

In this study, UGI lesions were found in 36.4% of the patients. Hence treating either one of them will lead to persistence of symptoms post treatment.

Thus, we recommend an UGI-Scopy pre-operatively for patients undergoing elective laparoscopic cholecystectomy for gallbladder stone disease for adequate diagnosis and treatment of the co-existing UGI lesions if present and reduce the incidence of post-operative persistence of symptoms.
