Q) Length of Esophagus
The esophageal length is anatomically defined as the distance between the cricoid cartilage and the gastric
orifice. It ranges in adults from 22 to 28 cm (24 ± 5 SD), 3 to 6 cm of which are located in the abdomen.
The shortest distance between the cricoid cartilage and the celiac axis is the orthotopic route in the posterior mediastinum, being 30 cm. The retrosternal (32 cm) and the subcutaneous route (34 cm) proved to be

Q. Best predictor in the GCS
A. Eye opening
B. Motor response
C. Verbal response
23) B, Motor response
Motor score is the best predictor of neurological outcome.
The m component of the GCS, is not only linearly related to survival, but preserves almost all the predictive power of the GCS
Q) Out of the following which will require Spinal immobilization most?
a. 22 yr Female had a high-speed motor vehicle collision who complains of backpain and no
b.16 yr male jumped from 6ft landed on both foot denies back pain and weakness
C. Gunshot injury
D. Abdominal injury
Answer is free
Spinal cord injuries are a common cause of morbidity and expenditure. Mortality is associated with cervical injuries but not lower spinal cord injuries.
Motor vehicle accidents are the most common cause and gunshot injuries the least common for spinal cord injuries.
Mechanism of injury
- Blunt trauma - Direct impingement, Ischemia, compression or bleeding
- Penetrating - Laceration of spinal cord
Chance fracture - is a type of spinal cord fracture in which there is transverse fracture of all vertebral elements
1 Complete immobilisation
2. Management of associated neurogenic shock ( due to loss of sympathetic tone) with vasopressors and fluids

Q) All are true about tropical pancreatitis except?
a. Associated with Tapioca.
b. Patients have large stones with fibrosis.
d) Onset of disease at 50 years
Answer d - Free. See here for other questions and this question
Onset 50 years
Tropical pancreatitis is an idiopathic disease which begins in teens. It has a high association with diabetes and Pancreatic duct calculi. It is common in South India, Asia, Africa and central America
These patients have increased risk of cancer
It is associated with SPINK 1 mutation
Q) Adverse factor for spontaneous fistula closure:
a) Tract <1cm
b)Transferrin > 200
c) Location in esophagus
d) First surgery done in the same institution
a) Tract less than 1 cm
Spontaneous fistula closure
Short-turnover protein (prealbumin, retinol-binding protein, transferrin) levels should be measured at least weekly to assess the adequacy of protein delivery. An ongoing catabolic state will adversely affect short-turnover protein levels, even with maximal protein delivery.
Failure of an enterocutaneous fistula to close spontaneously is associated with acronym FRIENDS):
the presence of a foreign body within the tract or adjacent to it, previous radiation exposure of the site, ongoing inflammation (most commonly from Crohn disease) or infection that contributes to a catabolic state, epithelialization of the fistula tract (particularly if the fistula tract is less than 2 cm long), neoplasm, distal intestinal obstruction, and pharmacologic doses of steroids.
Fistulas associated with a concurrent pancreatic fistula also have a low rate of spontaneous closure, as do those occurring in the presence of malnutrition or adjacent infection.
In general, anatomic locations that are favorable for closure are the oropharynx, esophagus, duodenal stump, pancreas, biliary tree, and jejunum.
Q Least useful investigation in a pt with recurrent LGI bleed, multiple upper and lower GI endoscopies negative
b) Double balloon enteroscopy
c) Capsule endoscopy
d) Push endoscopy
Free for all
Investigations in lower GI bleed should be specific and less time consuming
Small bowel enteroclysis, which uses a tube to infuse barium, methylcellulose, and air directly into the small bowel, yields better images than simple small bowel follow-through. Because the yield has been reported to be very low and the test is poorly tolerated, it is now rarely used.
Capsule endoscopy uses a small capsule with a video camera. capsule endoscopy is an excellent tool for the patient who is hemodynamically stable but continues to bleed, with reported success rates as high as 90% in identifying a small bowel pathology.
The hemodynamically stable patient should undergo small bowel enteroscopy. Usually performed with a pediatric colonoscope, it is referred to as push endoscopy. It can reach about 50 to 70 cm past the ligament of Treitz in most cases and permits endoscopic management of some lesions. Overall, push enteroscopy is successful in 40% of patients .
Double-balloon endoscopy is another technique gaining in popularity. Although technically difficult, this approach is capable of providing a complete examination of the small bowel. In expert hands, double-balloon enteroscopy can identify a bleeding source in 77% of cases with occult bleeding, with the yield increasing to over 85% if the endoscopy is per-formed within 1 month of an overt bleeding episode.The advantage of this technique is that as well as visualization, biopsies can be performed and therapeutic interventions undertaken.
To conclude investigations in lower GI bleed have to be specific and have high sensitivity also.
Q After esophagectomy ICD draining 800 – 1000ml chyle 5-7 days post operatively. Next management
a) NPO, TPN
b) Enteral feeding with medium chain
c) Re explore and suture the defect
Once the diagnosis is made, one should ensure the pleural space is completely evacuated; if needed, drainage is done by a chest tube or a radiologically directed catheter placement.
Feedings are stopped and total parenteral nutrition (TPN) is started. The amount of chest tube output is then monitored for several days in order to make a decision about the possible need for reoperation. Small leaks can seal with nonoperative therapy. Large initial daily outputs (typically greater than 1 L/day) often fail nonoperative therapy and require reoperation. An absolute amount of drainage for prediction of failure is unknown and one should consider also if there is a gradual reduction in daily output to continue with conservative therapy.
If the drainage is less than 500 mL per day and slowly decreasing, continued conservative therapy is frequently successful. Continued volumes more than 1 L after 2 days of TPN is a good indication of the need for reoperation. In general, it is better to be more rather than less aggressive in returning to the operation theater with a chylothorax. It was more common after THE and was associated with longer intensive care unit (ICU) and hospital stays. There was no difference in mortality between those with and without a chylothorax.
Patients with initial drainage exceeding 2 L within 2 days of starting conservative treatment all required reoperation.
Q) Newest treatment for anal incontinence?
a. Sacral nerve stimulation
b. Artificial sphincter.
c. Repair of sphincter
d. Gluteus maximus graft
Sacral nerve stimulation is the newest modality in treatment for anal incontinence. In it electrodes are placed via the sacral foramina. The nerve supply of anal sphincter is similar to lower extremity so their stimulation can lead to contraction of various foot muscles.
Others are all older methods

Q ) Modified Nissen's Fundoplication
a) 2700 anterior wrap around esophagus
b) 2400 wrap
c) 3600 wrap over > 52 Fr for 1 – 2 cm
d) 600 wrap over 42 Fr for 4 cm
Nissen fundoplication is complete 360 degree but has high incidence of gas bloat. To counter this modification done to wrap over 52 F tube for 1-2 cm
Belsey - Left thoracotomy, mobilization of distal esophagus and stomach, hiatus opened from above, fundus is brought 270 degrees around distal esophagus. Then the whole assembly is brought down and crura is repaired.
Hill procedure - No fundoplication is done
Toupet is anterior fundoplication either 240 degree or 270 degree.
Q) True about foreign body in esophagus
a) Sharp objects should be operated and not retrieved
b) Lead batteries should be removed
c) Most common impacted foreign bodies are dentures
d) Contrast examination of esophagus should be done before endoscopy
Sharp objects can be removed over overtubes and not always require surgery. Lead batteries can corrode and decay in the stomach or intestine and should always be removed. Most common impacted foreign bodies are food boluses above a pathological narrowing and require endoscopic break up
Contrast examination is not always required and might complicate things

Q) According to Siewert classification tumors at GE junction are
a) Type I
b) Type II
c) Type III
d) Type IV
Answer (free for all)
Type I Lower (centre located within between 1-5cm above the anatomic OGJ)
Type II Real GE junction (within 1cm above and 2cm below the OGJ)
Type III (2-5cm below OGJ)
This classification has only 3 subtypes
According to the Siewert-Stein classification,
Type I tumour 25% approx
Type II - Most common 49%
Type III was present in 25%
This classification helps in deciding the operative management and unified pre op classificationT
Types of Surgery
Type I cancer--depending of the size of the tumour--distal 2/3 oesophagectomy with the resection of the proximal lesser curve of the stomach or total gastrectomy or THE
In patients with types II and III cancers total gastrectomy
Q) Which is the strongest layer of the intestine?
c) Muscularis propria
d) Muscularis mucosa
b) Submucosa is the strongest and most important layer for intestinal anastomosis. It has fibroblasts that will ultimately release collagen and hold the anastomosis together. This layer should be fully incorporated in the anastomosis.
Inverted Vs everted anastomosis of intestine debate has been log going on but now many prefer inverted because mucosa is exposed to mucosa and eventually degrades joining the two submuoca together to cause healing by primary intention.
