Lymph nodes in neck

by

Q) Most common site for lymph node spread is ? (head and neck Onco) 

a) Tongue

b) Lip

c) NAsopharynx

d) Glottis

Ans c

 Primary sites within the pharynx (i.e., nasopharynx, oropharynx, and hypopharynx) and supraglottic larynx  are particularly high risk.

The oral cavity has an intermediate risk,

whereas the glottic larynx, nasal cavity, and paranasal sinuses are low risk. Other predictors of risk of metastases are higher T stage and thickness (in case of oral cavity cancers).

Bladder Cancer

by

Q) What is the most suitable treatment option for non muscle-invasive bladder cancer with the risk of recurrences?

A)Cystectomy

B)Intravesical chemotherapy

C)Transurethral resection and adjuvant intravesical chemotherapy

D)Palliative therapy

Answer-C(Schwartz-1654)

Patients with non–muscle-invasive bladder cancer (confined to the bladder mucosa or submucosa) can be managed with transurethral resection alone and adjuvant intravesical (instilled into the bladder) chemotherapy/immunotherapy.

The use of these intravesical agents is critical since patients with non–muscle-invasive bladder cancer are at risk for tumour recurrence and progression.

Sugiura Procedure

by

Q)   What is not true regarding Sugiura's procedure for Portal Hypertension ?

a)  It is a transesophageal variceal ligation

b) Splenectomy is done

c) Vagotomy is done 
d) Pyloroplasty is done
Sugiura procedure is the non shunting procedure for EV bleeding, which was first proposed by Sugiura and Futagawa in 1973 []. However, because of its complexity and high postoperative morbidity and mortality, this procedure has not been widely accepted in Western countries 

a

Non shunt operations are done for bleeding esophageal varices in emergency for poor risk patients when sclerotherapy or other conservative methods fail.
Sugiura's is a devascularization procedure described in 1973
It has two parts
Thoracic and abdominal which may be simultaneous or staged.
The Left posterolateral thoracotomy is done.
The longitudinal periesophageal azygous collateral veins and thoracic vagus is preserved. 
The esophagus is transected at level of diaphragm. This completely  devascularizes the esophagus.
The cut mucosa and anterior muscle layer is approximated.
Then the abdominal approach is done and abdominal esophagus, cardia of stomach is devascularized. Short gastric vessels are ligated, selective vagotomy is done, pyloroplasty is done, splenectomy completes the procedure.
Transgastric varix ligation was done previous to this procedure as described by Tanner  but not transesophageal. Hence 'a' is the answer.
The modified Sugiura procedure can be performed through a one-stage transabdominal approach via the midline incision or extension of a left subcostal incision with the exposure of an L shape.
The procedure starts with splenectomy for improvement of the exposure followed by gastric and esophageal devascularization and finally the esophageal transaction using a mechanical stapler through a short gastrotomy.
The Sugiura operation contains five componential procedures and esophagogastric devascularization is the only remaining part in the many different versions of the modified Sugiura operation.

Hormones released from duodenum

by

 

 

 

Q. Which of the following hormones are not released in the duodenum?
a) Gastrin
b) Motilin
c) Somatostatin
d) Pancreatic YY
Correct Answer: d) Pancreatic YY

  • Gastrin – secreted mainly by G-cells in the stomach, and in small amounts from the duodenum.
  • Motilin – secreted by M cells in the duodenum and jejunum.
  • Somatostatin – secreted by D-cells throughout the GI tract, including the duodenum.
  • Pancreatic YY (PYY) – secreted by L-cells in the ileum and colon, not in the duodenum.

Bevacizumab

by
Bevacizumab MCQ
Q) Not true about use of Bevacizumab
a) It is a humanized monoclonal antibody against VEGF A
b) Bevacizumab is a first-line treatment in metastatic nonsquamous non-small cell lung cancer.
c) Bevacizumab is a first-line or second-line therapy for metastatic colorectal cancer
d) Its major advantage is that it has replaced combination chemotherapy
Correct Answer: d) Its major advantage is that it has replaced combination chemotherapy
Explanation: a) True – Bevacizumab is a humanized monoclonal antibody targeting vascular endothelial growth factor A (VEGF-A), thereby inhibiting angiogenesis. b) True – Bevacizumab is used as first-line treatment in combination with chemotherapy for metastatic nonsquamous non-small cell lung cancer (NSCLC). c) True – Bevacizumab is used as first-line and second-line therapy in combination with chemotherapy for metastatic colorectal cancer. d) Not true – Bevacizumab is not a replacement for combination chemotherapy. Instead, it is used in combination with standard chemotherapy regimens to improve efficacy. It is not used as a monotherapy in most settings.

a) Stage II
b) Stage IIIA
c) Stage IIIB
d) Stage IV (M1)
Correct Answer: c) Stage IIIB
Explanation: Primary tumor (T) TX: primary tumor cannot be assessed T0: no evidence of primary tumor Tis: carcinoma in situ (Bowen disease, high-grade squamous intraepithelial lesion [HSIL], anal intraepithelial neoplasia II-III [AIN II-III]) T1: tumor 2 cm or less in greatest dimension T2: tumor >2 cm but <5 cm in greatest dimension T3: tumor >5 cm in greatest dimension T4: tumor of any size invades adjacent organ(s), e.g. vagina, urethra, bladder (Note: direct invasion of the rectal wall, perirectal skin, subcutaneous tissue, or the sphincter muscle(s) is not classified as T4) Regional lymph nodes (N) Nx: regional lymph nodes cannot be assessed N0: no regional lymph node metastasis N1: metastasis in regional lymph nodes N1a: metastases in inguinal, mesorectal, and/or internal iliac lymph nodes N1b: metastases in external iliac lymph nodes N1c: metastases in external iliac and in inguinal, mesorectal, and/or internal iliac lymph nodes Distant metastasis (M) Mx: distant metastasis cannot be assessed M0: no distant metastasis M1: distant metastasis (Note: involvement of para-aortic or more distant lymph nodes is considered M1) AJCC Staging: Stage 0: Tis N0 M0 Stage I: T1 N0 M0 Stage II: T2, T3 N0 M0 Stage IIIA: T1, T2, T3 N1 M0 Stage IIIB: T4 N0/N1 OR T1, T2, T3 with N1b or N1c Stage IV: Any T, any N, M1

Healing by Primary Intention

by

Q)What is  false regarding the healing by  primary intention? ( # Gen surgery Wound Healing) 

A)Wound edges opposed.

B)Normal healing.

C)Usually done for dirty wounds

D)Minimal scar.

Answer-C

Primary intention,

Healing by primary intention is also known as healing by the first intention this occurs when there is an opposition of the wound edges

Secondary Intention

Healing occurs when the wound edges are not opposed immediately, which may be necessary for contaminated or untidy wounds.

Primary intention,

  • Would edges opposed
  • Normal healing.
  • Minimal scar.

Secondary intention,

  • Would leave open.
  • Heals by granulation, contraction and epithelialisation.
  • Increased inflammation and proliferation.
  • Poor scar.

Intestinal Tuberculosis

by
False about Intestinal TB - MCQ

Q) Which of the following statements about intestinal tuberculosis is false?

1. Hyperplastic type commonly causes colonic strictures
2. Raised inflammatory markers, anemia, and positive sputum culture support the diagnosis
3. Barium meal follow-through may show a pulled-up cecum
4. Interferon-gamma release assay is diagnostic

Answer: A) Strictures are of the small bowel, not the colon

Explanation:

Intestinal tuberculosis occurs in two main forms:

1. Ulcerative type – Characterized by transverse ulcers with undermined edges, and the serosa is studded with tubercles. This represents a more severe form of the disease.

2. Hyperplastic type – Involves hyperplasia and thickening of the terminal ileum. It leads to narrowing of the lumen, stricture formation, and fibrosis of the terminal ileum, not the colon.

Other key points:

  • Raised inflammatory markers and anemia are commonly seen.
  • Interferon-gamma release assays help in detecting subclinical infection but are not diagnostic.
  • Barium meal follow-through typically shows a pulled-up or subhepatic cecum.

d) Group 4

More question at www.mcqsurgery.com/hydatid

WHO Informal Working Group on Echinococcosis (WHO-IWGE) classification

Group 1: Active group – cysts larger than 2 cm and often fertile.
Group 2: Transition group – cysts starting to degenerate and entering a transitional stage because of host resistance or treatment, but may contain viable protoscolices.
Group 3: Inactive group – degenerated, partially or totally calcified cysts; unlikely to contain viable protoscolices.
