Abstract
Introduction
Obstructive jaundice is associated with high morbidity and mortality. Obstructive jaundice is not a definitive diagnosis. Detailed evaluation to establish the etiology of the cholestasis and cause of obstruction is crucial to avoid secondary pathologic changes and to plan different surgical techniques to intervene at an early stage.
Materials and Methods
A cross-sectional study was conducted among 50 cases of surgical obstructive jaundice at Shri Ram Murti Smarak Institute of Medical Sciences (SRMSIMS), Bareilly.
Results
The mean age of this study population was 48.44 ± 8.2 years, and 48% (24) patients had obstructive jaundice of benign etiology, whereas 52% (26) had malignant etiology. Among males, the common presentation was choledocholithiasis in benign disease and carcinoma of the gallbladder among malignancy. In females also, disease presentation was similar to that of males. Percutaneous transhepatic biliary drainage (PTBD) was the most common method of biliary decompression in malignant group. For biliary decompression in patients of benign etiology, common bile duct (CBD) exploration with T-tube drainage was done in most cases.
Conclusion
Obstructive jaundice has different etiologic spectrum in both males and females. Irrespective of etiology, common presentation was pain (94% of the cases). Most patients with malignant etiology presented with palpable lump. PTBD was the most common method of biliary decompression in malignant group. CBD exploration with T-tube drainage has higher values of decrease in serum bilirubin, serum bilirubin (indirect), serum alkaline phosphatase, and albumin.

Introduction
Jaundice (derived from French word “Jaune” for yellow) or icterus (Latin word for “Jaundice”) means yellowish staining of the skin, sclera, and mucous membranes due to deposition of bilirubin (a yellow orange bile pigment) in these tissues.1,2 Jaundice was once called the morbus regius (the regal disease) in the belief that only the touch of a king could cure it. Jaundice can be classified into pre- or posthepatic. The causes of posthepatic jaundice (obstructive or surgical cholestasis) are more relevant to surgeons. Patients with obstructive jaundice have very high morbidity and mortality; early diagnosis of the cause of obstruction is very important, especially in malignant cases, as resection is only possible at an early stage. Obstructive jaundice is not a definitive diagnosis, and early evaluation to establish the etiology of the cholestasis is crucial to avoid secondary pathologic changes (e.g., secondary biliary cirrhosis) if obstruction is not relieved.3 Obstructive jaundice is the most common type with which the surgeon has to deal. It has its origins in the liver and is due to gradual or sudden, partial or complete, temporary or permanent obstruction, either within or without the ducts to the flow of bile. Complete or partial obstruction may result from tumor formation at the papilla of Vater, in the common bile duct (CBD), in the head of pancreas, or it may be due to stone formation and stricture of papilla of Vater, stricture of CBD, or hepatic duct.4,5 While it is possible for small stones to pass through the papilla of Vater, larger ones will lodge at this point, with increased obstruction as the result of inflammation caused by their presence. Biliary obstruction results in hepatocyte disfunction and release of enzymes into circulation such as transaminases, alkaline phosphatase (ALP), bilirubin, etc.6,7 Estimation of serum albumin in obstructive jaundice indicates the synthetic function of the liver. Increased nitric oxide production in hepatocytes is involved in liver dysfunction following obstructive jaundice. Obstructive jaundice damages critical functions in the liver. However, the mechanisms involved in hepatic dysfunction are obscure. Nitric oxide is implicated in liver injury under various pathologic conditions. Derangement of liver functions in obstructive jaundice has been known to influence surgical outcome.8,9 The pattern and time frame of liver function recovery in patients with surgical obstructive jaundice undergoing a bilioenteric anastomosis has not been comprehensively defined in human beings. Liver function tests by themselves do not contribute to etiology or the lesions leading to surgical obstructive jaundice, and other radiologic and endoscopic investigations are necessary before surgical treatment. None of the liver function test enables the surgeon to accurately assess the functional capacity of the liver while investigations recommended should be performed in a standardized manner. Obstructive jaundice poses diagnostic challenge to general surgeon practicing in resource-limited countries. This study is conducted to understand the clinical profile and different management techniques of surgical obstructive jaundice cases.
Materials and Methods
Study Design
This is a cross-sectional, descriptive study.
Study Setting
This study was conducted at Shri Ram Murti Smarak Institute of Medical Sciences (SRMSIMS), Bareilly, a tertiary care teaching hospital.

aPruritus/clay-colored stools/high-colored urine.
Most patients, irrespective of etiology, presented with pain (94%), followed by pruritus (40%); 30% of patients, mostly of malignant etiology, presented with palpable lump, and 54% of patients with carcinoma of the gallbladder presented with palpable mass, thus supporting Courvoisier's law. Scratch marks were seen in equal percentage of patients among the benign and malignant conditions (►Table 4).

Percutaneous transhepatic biliary drainage (PTBD) was the most common method of biliary decompression in malignant group as most patients came in advanced malignant stage. PTBD was done as palliative procedure in 17 cases. Whipple's operation was done in five cases (carcinoma head of pancreas, periampullary carcinoma, and cases of cholangiocarcinoma). Hepaticojejunostomy and choledochoduodenostomy was done in one case each. For biliary decompression in patients of benign etiology, CBD exploration with T-tube drainage was done in 20 cases. Four patients were referred for endoscopic retrograde cholangiopancreatography (ERCP) or stenting.
Biochemical Findings in Percutaneous Transhepatic Biliary Drainage versus Common Bile Duct Exploration of Management
Serum bilirubin: There was significant decrease in serum bilirubin (direct) after PTBD. In nearly 88.23% of patients, the decrease in serum bilirubin was in between 10 and 50% of the initial preoperative value. In 5.8% of patients, fall in bilirubin was greater than 50%. In biliary decompression following CBD exploration with T-tube drainage there, 75% patients had decrease in serum bilirubin between 10 and 50%. In 15% of patients, the decrease in serum bilirubin was more than 50%.
Serum bilirubin (indirect): Following biliary decompression after PTBD, the fall in serum bilirubin (indirect) was between 10 and 50% in 64.7% of patients. In 35% of patients, the fall in serum bilirubin indirect was more than 50%. After CBD exploration with T-tube drainage, the decrease in serum bilirubin indirect was between 10 and 50% in 25% of patients. In 55% of patients, the fall in serum bilirubin was more than 50% of initial value.

SGOT: After PTBD in 35% of patients, the decrease in SGOT was between 10 and 50%. In 52% of patients, there was increase in SGOT. After CBD exploration in 45% of patients, the fall in SGOT level was between 10 and 50%. In 35% of patients, there was increase in SGOT.
Serum ALP showed a significant decrease after PTBD. In 88.23% of patients, the fall in ALP was between 10 and 50%. In 11.26% of patients, decrease in value more than 50% was shown. Following CBD exploration with T-tube drainage, 65% of patients showed fall in value between 10 and 50%. In 50% of patients, the decrease in value was greater than 50%.
PT: In 76.47% of patients, the decrease in PT was between 10 and 50%. In 5.8% of patients, the decrease in value was greater than 50% following PTBD. After CBD exploration with T-tube drainage in 25% of patients, there was increase in value after biliary decompression.
Albumin: In 70.58% of patients, there was increase in albumin level between 10 and 50%. In 5.8% of patients, there was decrease in value after PTBD. After CBD exploration in 40% of patients, there was decrease in albumin level between 10 and 40% of patients. In 10% of patients, there was decrease in the serum albumin.
Discussion
This study results were in consensus with most studies where malignant causes were the common reason for surgical obstructive jaundice, except the study conducted by Huis et al where most (74%) cases were due to benign causes13 (►Tables 5and6).

| This study | 2 | 57.6 | 19.8 | 7.06 | 38 |
Abbreviations: CAGB, carcinoma of gallbladder; CAPN, carcinoma of pancreas.
This study findings were similar to the study conducted by Sharma et al, whereas as per studies conducted by Siddique et al and Huis et al, choledocholithiasis is the common etiology.
CBD exploration with T-tube drainage has higher values of decrease in serum bilirubin, serum bilirubin (indirect), serum ALP, and albumin when compared with the initial values in relation to biliary decompression after PTBD.
Conclusion
Obstructive jaundice has different etiologic spectrum in both males and females. Benign causes are seen at comparatively younger age group as compared with malignant causes. Gallbladder carcinoma was the most common malignant etiology, whereas choledocholithiasis was the most common benign cause. Irrespective of etiology, common presentation is pain (94%), followed by pruritus (40%). Most patients with malignant etiology presented with palpable lump. PTBD was the most common method of biliary decompression in malignant group. CBD exploration with T-tube drainage has higher values of decrease in serum bilirubin, serum bilirubin (indirect), serum ALP, and albumin.
Note
Recommendations: Obstructive jaundice is a clinical diagnosis that requires both clinical and diagnostic workup to elucidate the precise etiology–a multidisciplinary approach that requires the better outcome.
