Laparoscopic Cholecystectomy
1. The hepatocystic triangle is cleared of peritoneum, fat and fibrous tissue. The hepatocystic triangle is defined as the triangle formed by the cystic duct, the common hepatic duct, and inferior edge of the liver. The common bile duct and common hepatic duct do not have to be exposed.
2. The lower one third of the gallbladder is separated from the liver to expose the cystic plate. The cystic plate is also known as liver bed of the gallbladder and lies in the gallbladder fossa.
3. Two and only two structures should be seen entering the gallbladder.

Myocardial infarction (Heart Attack)
Heart
muscle is the hardest working muscle of the body which pumps approximately 4-5
litre of blood ever minute during rest. Only coronary arteries supply blood to
heart muscle. Blood flowing through the chambers of the heart is not useful for
the heart muscle.
Heart attack or Myocardial infarction (MI) is the irreversible necrosis (death) of heart muscle secondary
to prolonged ischemia (lack of oxygen supply). This usually is the result of a
blockage in one or more of the coronary arteries. During last 30 years, large
decline of MI incidence in developed countries and alarming increase in
developing countries like India.
Etiology
Atherosclerosis: Atherosclerosis
is a condition in which there is gradual plaque build-up within artery walls,
resulting in narrowing of artery. Atherosclerosis is the disease primarily
responsible for most acute coronary syndrome (ACS) cases.
Coronary artery disease (CAD) or Coronary heart disease (CHD): when atherosclerosis occurs in coronary arteries, heart does
not get sufficient blood, the condition called coronary artery disease or
coronary heart disease.
Non-modifiable risk factors:
Ø Age: Men are at a higher risk of heart attack after age 45 and women
after age 55.
Ø Family history: A positive
family history of MI in first-degree male relative aged 45 years or younger and
first-degree female relative aged 55 years or younger.
Ø Male-pattern baldness.
Modifiable risk factors:
Ø Smoking or other tobacco use.
Ø Bad cholesterol (LDL), is one of the leading causes of a
blockage in the arteries.
Ø Saturated fats may
also contribute to the build-up of plaque in the coronary arteries. Saturated
fats are found mostly in meat and dairy products, including beef, butter, and
cheese.
Ø Trans fat contributes to clogging of arteries. Trans fat is usually
artificially produced and can be found in a variety of processed foods.
Ø Diabetes mellitus: High blood sugar levels can damage blood vessels and
eventually lead to coronary artery disease.
Ø Hypertension: High blood pressure damages arteries and accelerates the
build-up of plaque.
Ø Obesity (abdominal obesity)
Ø Psychosocial stress
Ø Sedentary lifestyle and/or lack of exercise
Ø Reduced consumption of fruits and vegetables
Ø Poor oral hygiene
Ø Type A personality
Ø Elevated homocysteine levels
Symptoms
Ø Chest pain: The typical chest pain of acute MI usually is
intense and unremitting for 30-60 minutes. It is retrosternal and often
radiates up to the neck, shoulder, and jaws, and down to the left arm. The
chest pain is also perceived as squeezing, aching, burning, or even sharp.
Ø There may have prodromal symptoms of fatigue, chest discomfort,
or malaise in the days preceding the event; alternatively, typical ST-elevation
MI (STEMI) may occur suddenly without warning.
Ø Profuse sweating.
Ø Shortness of breath.
Ø Anxiety, commonly described as a sense of impending doom.
Ø Light headedness, with or without syncope.
Ø Coughing, wheezing, and the production of frothy sputum may occur.
Ø Nausea, with or without vomiting.
Ø In some patients, the symptom is epigastric, with a feeling of
indigestion or of fullness and gas.
Ø Many Myocardial infarctions are either "silent" or are
not clinically recognized by patients, families, and health care providers.
Signs
Ø Tachycardia: The patient’s heart rate is often increased.
Ø Irregular Pulse.
Ø Blood Pressure: BP initially elevated because of peripheral arterial
vasoconstriction. Later, with right ventricular MI or severe left ventricular
dysfunction, there is hypotension (fall in BP) and cardiogenic shock can be
seen.
Ø Tachypnoea: The respiratory rate may be increased in response to
pulmonary congestion or anxiety.
Investigations
Ø Electrocardiography (ECG):
o ECG is most important tool in the initial evaluation. ST-segment elevation greater than 1 mm in
two anatomically contiguous leads or presence of new Q waves.
o Intermediate-probability: ST-segment
depression or T-wave inversion.
o Low-probability: Normal ECG findings or
nonspecific findings on ECGs do not exclude the possibility of MI.
Ø Cardiac biomarkers/enzymes:
o Cardiac troponin should be measured at presentation in suspected MI.
o Troponin is a contractile protein that is not normally found in serum;
it is released only when myocardial necrosis occurs.
o Serum levels increase within 3-12 hours from the onset of chest pain,
peak at 24-48 hours, and return to baseline over 5-14 days.
o Serial measurement of cardiac troponins after the initial level is normal
at presentation, 3 to 6 hours after symptom onset, is recommended.
Ø
Cardiac
imaging:
o
Coronary angiography in individual
with highly probable or confirmed acute MI can be used to definitively diagnose
or rule out coronary artery disease.
o
Multi-detector computed
tomography (MDCT) coronary angiography may be considered as an alternative to
invasive angiography to exclude ACS when cardiac troponin and/or ECG results
are inconclusive.
Prognosis
Ø Acute myocardial infarction is associated with a 30% mortality
rate; about 50% of the deaths occur prior to arrival at the hospital.
Ø Approximately half of all patients with an MI are re-hospitalized
within 1 year of their index event.
Ø Better prognosis is associated with:
o Successful early reperfusion (ST-elevation MI goals: patient
arrival to fibrinolysis infusion within 30 minutes or percutaneous coronary
intervention within 90 minutes.
o Preserved left ventricular function.
o Short-term and long-term treatment with beta-blockers, aspirin,
and ACE inhibitors.
Ø Poorer prognosis is associated with the following factors:
o Advanced age.
o Diabetes mellitus.
o Previous cerebrovascular disease or peripheral vascular disease.
o Delayed or unsuccessful reperfusion.
o Poorly preserved left ventricular function.
o Evidence of congestive heart failure.
o Involvement of electrocardiograph (ECG) lead aVR.
o Depression.
Management
Prehospital care
Ø Intravenous access,
Ø Supplemental oxygen if SaO2 is less than 90% on
pulse oximetry.
Ø Aspirin: Aspirin preferably chewable
should be given in a dose of at least 162 to 325 mg
for fibrinolytic therapy, unless there is a clear history of aspirin
allergy.
Ø Nitroglycerin: Nitroglycerin 0.4
mg tablet sublingually or by spray should be given
as it relaxes venous system reducing workload of the heart thereby help in chest
pain. If relief is experienced within 5 minutes of the first Nitroglycerin dose,
repeated doses can be given every 5 minutes for a maximum of 3 doses total.
Ø Nitroglycerin should be avoided in
hypotension or bradycardia.
Ø Telemetry and prehospital ECG, if available
Ø Adequate
analgesia: Morphine in initial dose of morphine of 2 to 4 mg as an IV bolus can
be given, repeated every 5 to 10 minutes until the pain is relieved.
Ø The
use of NSAIDs should be avoided as these are associated with adverse
cardiovascular events.
Emergency department and inpatient care:
Ø The
first goal for healthcare professionals in management of acute myocardial
infarction (MI) is to diagnose the condition in a very rapid manner.
Ø Resuscitation
of the patient.
Ø Initial
therapy is directed toward restoration of perfusion as soon as possible to
salvage as much of the jeopardized myocardium as possible. This may be
accomplished through medical or mechanical means, such as percutaneous coronary
intervention (PCI), or coronary artery bypass graft (CABG) surgery.
Ø Angioplasty (Percutaneous coronary
intervention): A thin, flexible tube with a balloon on
the end is threaded through a blood vessel to the blocked coronary artery.
Then, the balloon is inflated to push the plaque against the wall of the
artery. This widens the inside of the artery, restoring blood flow. Also a
stent may be put in the artery to help keep it open.
Ø Coronary artery bypass
grafting (CABG): It is a surgery in which
arteries or veins are taken from other areas of body and sewn in place to go around
the blocked coronary arteries. This provides a new route for blood flow to the
heart muscle.
Lifestyle modifications
Ø Dietary changes: A low-fat and low-salt diet with dietary counseling,
Ø Quit Smoking
Ø Regular exercise: The recommended frequency of regular exercise training is three or more times a week, for at least 30 minutes per session.
Ø Possible goal numbers for your risk factors include:
o Blood
pressure lower than 140/90 mm Hg
o Waist
circumference lower than 35” for women and 40” for men
o Body
mass index (BMI) between 18.5 and 24.9
o Blood
cholesterol under 180 mg/dL
o Fasting
Blood glucose under 100 mg/dl

Multiple Myeloma
Life Expectancy
of Newly diagnosed Multiple Myeloma patient:
My family’s
experience
Whenever a person, who in most
instance otherwise looks healthy, diagnosed Multiple Myeloma, the first fearful question comes to mind is how long he/she will survive. Same question also came
in my Brother’s mind who was just 48 when he was diagnosed for Multiple
Myeloma. He was just having low backache, no other symptoms.
I sat by his side and he asked me:
Bhaiya (Brother), everything is finished? As the articles on internet he read showed
that he would not survive for more than 9 months. It was painful for both of us
but being a doctor, I assured him that don’t go on what is written on net and
we will fight and I will not let him go.
He was thoroughly investigated and the
treatment started under the guidance of one of the finest Oncologist for
Multiple Myeloma at AIIMS, Delhi. First chemotherapy and later autologous Stem
Cell transplant, everything was going as planned. My brother was obese, moderate alcoholic and occasional smoker. He stopped these intoxications and
started light exercise to reduce weight. He stuck to a healthy diet as
prescribed to him.
Later, the symptoms gradually started
subsiding, Hb% improving and so was other parameters. Every one of us including
my brother started feeling relaxed, though we know that there will be
relapse someday. We all forgot that the literature says life expectancy
in current situation is 3 to 5 years. Gradually his daily routine started to what
it was before the disease including diet, exercise and other habits.
Do
we have to relax at this stage?
I still curse myself that being a doctor;
it was my responsibility to tell my brother (who was not a medical
professional) that the disease is still there in his body and that we cannot afford
to relax. It was my duty to realize him that on first occasion his body able to
bear the brunt of disease but next time when there will be relapse, the same
body might not be in a stage to bear the injury. So this should be the time
when we should be more focused to prepare a body system which is much
fitter.
Since there is no cure of Multiple
Myeloma till date, we should accept that the disease will take its own course.
There may be complete remission followed by early or delayed relapse. We should
be more focused especially in remission phase on how we can prepare our body to
fight the relapse.
If
the patient has to live longer, if he has to erase the 3 years survival
destiny, he has to continue all those instruction more stringently during
remission phase, which was advised to him when he was first diagnosed the
disease. Few of these are:
1. No Alcohol: Better would be no addiction including
smoking, chewing tobacco or Gutkha besides forgetting alcohol.
2. No Obesity: Gradual but
continuous reducing the weight with balanced diet and continuous exercise. It
would be better if the patient do exercise under medical supervision as he has
weak bones which are more prone to get damaged. The exercise should gradually
be increased over a period.
3. Strict diet Plan: A healthy diet
keeping more of fruits, vegetables, proteins and less of carbohydrates, sugar,
packed / processed foods.
4. Develop Muscle Mass: I believe that
the patient should gradually develop his/her muscles, especially of extremities /
weight bearing areas.
5. No shortcut treatment: There are many advertisements in which it is claimed that they can cure the patient. You may get many such examples. But
believe me, all of them are fake and I am telling you from my personal
experience.
Lastly,
just leave the medical part on physician treating you but much more important
is how you prepare your body against the disease.

Multiple myeloma
Who left us for heaven on 22-11-2016 due to
Plasma cell Leukemia, a complication of
Multiple Myeloma
Multiple Myeloma (Plasma Cell Myeloma)
Multiple
Myeloma is a cancer of Plasma cells. Plasma cells are white blood cells that
secrete large volumes of antibodies. Plasma cells originate in the bone marrow
and are transported by the blood plasma and the lymphatic system. There is
abnormal plasma cell production and a subsequent overabundance of monoclonal M
protein which causes kidney problems and thickening of blood, also cause
formation of mass in the bone marrow or soft tissue. When only one mass is
present, it is referred as Plasmacytoma. When more than one mass is present, it
is referred as Multiple Myeloma. Multiple Myeloma usually occurs in elderly and
is more common in men.
Cause:
Ø Unknown
Ø Drinking alcohol and obesity are risk factors.
Each increase of body mass index by 5 is supposed to increase the risk by 11%.
Ø Familial predisposition to myeloma exists.
Survival:
Ø Without treatment, survival is supposed to be
around 7 months.
Ø With current treatments, survival is usually 4
to 5 years.
Ø Above mentioned survival periods are shocking
for a newly diagnosed MM person but I would like to share my personal
experience of the reality I believe the reason of such short life expectancy in
my next note "Life Expectancy of
Newly diagnosed Multiple Myeloma patient: My family's experience"
Symptoms:
1.
Bone pain:
The diagnosis is incidental in 30% of cases, discovered during routine blood
screening done for unrelated problems. 70% of patients have bone pain at
presentation. Sudden pain, usually worse with movement and at night due to a
broken bone in the spine, ribs, or elsewhere. Local bone damage and
osteoporosis (general thinning of the bone)
2.
Anemia:
Persistent tiredness and fatigue due to anemia. Anemia is because normal red
blood cells are crowd by myeloma plasma cells.
3.
Kidney damage or failure: High Blood calcium level result in kidney
damage, causing weight loss, nausea, thirst, muscle weakness, and mental
confusion.
4.
Recurrent unexplained infections: Like pneumonia, sinus, or urinary infection
5.
Swelling over
body, shortness of breath or evidence of heart or kidney failure.
6.
Bleeding:
Bleeding resulting from thrombocytopenia. Bleeding from nose (Epistaxis) may be
a presenting symptom.
Lab test findings:
1.
Decrease Hb%,
WBCs, Platelets
2.
Increased Bl.
Calcium, Bl. Creatinine, Protein level in the blood and/or urine. A 24-hour
urine collection for quantification of the Bence Jones protein (ie, lambda
light chains), protein, and creatinine clearance is required.
3.
M-SPIKE: Presence
of monoclonal protein in the blood and/or urine. The M-SPIKE is produced by the
cancerous myeloma cells present in the bone marrow. In general, the amount of
M-SPIKE reflects the amount of myeloma.
4.
Lytic bone
lesions or osteoporosis. A conventional complete plain skeletal survey usually
depicts lytic lesions.
5.
C-reactive
protein (CRP) is useful for prognosis.
6.
Bone marrow
aspirate and biopsy: To calculate the % of plasma cells,
7.
The Kappa/Lambda
Ratio:
a. When the level of either kappa or lambda is
very high and the other chain is normal or low, then the ratio is abnormal and
indicates that the myeloma is active.
b. When the levels of both kappa and lambda light
chains are increased, the ratio may be within the normal range, it generally
indicates a disease other than myeloma, such as poor kidney function.
c. When the kappa and lambda levels are both
within the normal range but the ratio abnormal, then there may be a persistent
low level of active myeloma with excess production of the abnormal light
chains.
d. A normal kappa/lambda ratio after treatment is
a particularly good remission and is termed a stringent complete response.
Normalization of the kappa/lambda ratio correlates with possible longer
remissions.
MGUS-
monoclonal gammopathy of undetermined significance: This is predominantly a
benign condition. The risk of developing active myeloma is very low: 1%/year.
Thus, after 20 years, 80% of patients have not developed active myeloma. MGUS
Diagnostic Criteria: All Three Required:
Ø Serum monoclonal protein and/or urine
monoclonal protein level low.
Ø Monoclonal bone marrow plasma cells < 10%.
Normal Serum Calcium, Hemoglobin and Serum Creatinine level.
Ø No bone lesions on full skeletal X-ray survey
and/or other imaging if performed.
Smoldering myeloma (low risk): Very similar to MGUS. Approximately 50% of
patients will develop myeloma within 18-24 months. Smoldering or Indolent
Myeloma Diagnostic Criteria: All Three Required:
Ø Monoclonal protein present in the serum and/or
urine
Ø Monoclonal plasma cells present in the bone
marrow and/or a tissue biopsy.
Ø Not meeting criteria for MGUS, multiple
myeloma, or solitary plasmacytoma of bone or soft tissue.
Plasma Cell
Leukemia: A dreaded complication of Multiple Myeloma. The survival rate of
these patients with present available treatment modalities are very poor.
Treatment:
1. Currently No Cure for MM.
2. Autologous stem cell transplantation,
radiation and surgical care in certain cases, have helped to lessen the
occurrence and severity of adverse effects of this disease.
3. Chemotherapy and immunosuppression: Several
drug therapies are valuable in the treatment of symptomatic MM.
a. Thalidomide, either as a single agent or in
combination with steroids.
b. Lenalidomide plus dexamethasone
c. Bortezomib plus melphalan
d. VAD (vincristine, doxorubicin and
dexamethasone)
e. Melphalan plus prednisone
4. Adjunctive therapy may also include:
a. Erythropoietin
b. Surgical intervention
c. Plasmapheresis
5. Autologous
Stem Cell Transplant: The first step
before starting therapy in MM is to determine whether a patient is a candidate
for an autologous stem cell transplant. Eligibility depends primarily on the
patient’s age and comorbidities. Typically an age of 65 years is used as a
cut-off point for transplant eligibility. Using the patient’s own bone marrow
or peripheral blood stem cells facilitates more intense therapy for MM. After
harvesting the stem cells from the patient, physicians can use otherwise lethal
doses of total body irradiation and chemotherapy and then “rescue” the patient
by reinfusing the harvested cells.
6. Physical
Activity: Patients should be encouraged to be
physically active to the extent appropriate for their individual bone status.
Physical activity may help maintain bone strength.
7. Black Cumin
seed oil: Thymoquinone, an extract of black
cumin seed oil is shown to be effective suppressor of tumour cell survival,
proliferation and angiogenesis in patient of Multiple Myeloma in one study.
Warning: The purpose
of this article is to create awareness for the disease mentioned above. The
reader of this article should exercise all precautions before following any information
provided above and it is advised that you consult your own physician or other
medical professional. The responsibility lies solely with the reader and not
