Colorectal Surgery Observership colon and rectal surgery, from staging to follow-up, in Istanbul

Watch how the general surgery team stages and plans colorectal cancer, chooses between minimally invasive and open resection, decides on anastomosis or stoma and manages colorectal emergencies — as a non-sterile observer on its lists where scheduled.

What can an observer follow in Colorectal Surgery?

What you see depends on the department's clinical calendar during your placement; the list below describes the department's usual scope, not a guaranteed programme.

Rectal cancer MRI review where colorectal cases reach the department's tumour boards: mesorectal fascia, extramural venous invasion, nodal status and neoadjuvant decisions
Colorectal resections by minimally invasive and open approaches, followed from outside the sterile field where scheduled
Anastomosis or stoma: how defunctioning and end stomas are decided, and stoma care planning before and after surgery
Emergency colorectal surgery as it arises during your attendance hours: obstruction, perforation and complicated diverticulitis
Pre-operative assessment, anaesthetic review and the enhanced-recovery pathway as it applies to bowel resection
Post-operative ward rounds — recognising anastomotic leak and ileus — and the department's morbidity and mortality meeting
Robotic colorectal resection only where the department performs it during your dates — confirmed after review

How is a colorectal operation chosen before the patient reaches theatre?

Rectal cancer shows how much of colorectal surgery is decided before the operation. High-resolution MRI defines the tumour's relationship to the mesorectal fascia, extramural venous invasion and nodal involvement, and these findings determine whether a patient proceeds directly to total mesorectal excision or receives radiotherapy, chemoradiotherapy or total neoadjuvant therapy beforehand. Where treatment produces a clinical complete response, selected patients may enter a watch-and-wait pathway rather than undergo resection. Colon cancer follows a simpler but parallel logic, with CT staging and a tumour board recommendation preceding surgery. Observers hear this reasoning where colorectal cases are on the agenda of the department's tumour boards.

In theatre, the choices concern approach and reconstruction. Minimally invasive resection is now standard for many elective cases, with open surgery kept for situations where it serves the patient better. Whether to restore continuity, protect a low anastomosis with a defunctioning ileostomy or create an end stoma depends on the tumour's level, the patient's fitness and the condition of the bowel. Stoma decisions are discussed with the patient beforehand, and stoma care planning is part of the pathway rather than an afterthought. Observers follow these choices from the theatre and the surgical clinic.

Emergency colorectal surgery compresses these decisions into hours. With a perforated diverticulum or an obstructing cancer, the operative choice often lies between resection with primary anastomosis, with or without a covering stoma, and a Hartmann's procedure, weighed against physiology and contamination; some obstructing cancers are first decompressed with a stent or a stoma. After elective and emergency surgery alike, the team watches for anastomotic leak, a complication that can transform a patient's recovery, and decides when imaging or a return to theatre is needed. The department's morbidity and mortality meeting revisits these calls, which makes it a valuable session for an observer.

How this page differs

Within general surgery, this focus isolates colon and rectal work, from staging to stoma care. Liver, pancreatic and biliary resection — including liver metastases from colorectal cancer — belongs to the HPB surgery focus, and colonoscopy, polypectomy and endoscopic resection sit with gastroenterology.

Who applies, and which route fits?

Clinical Observership

Graduates and junior surgeons considering a colorectal career who want to follow the pathway from MRI staging to stoma care and follow-up; clinical-year students gain a clear view of perioperative care.

Clinical Fellowship

General or colorectal surgeons with a specialist qualification who list colorectal surgery as their interest; the department decides how the attachment is allocated across its lists, with colon and rectal cases weighted where possible.

What an observer does not do

Both routes are strictly observational: observers attend theatre and clinic without patient contact, do not scrub or assist, and are not assessed on any procedure.

Anorectal work — haemorrhoids, fistula and pilonidal disease — is not named in the department's published scope; raise it during the review if it matters to you.
Theatre is followed as a non-sterile observer; there is no handling of instruments, specimens or stoma appliances.
Emergency cases are followed as they arise during attendance hours; no number of rectal resections, emergencies or specific operations can be promised.
No operative logbook credit or competence statement; the host hospital's certificate records attendance or completion.

Start	Rotations typically begin on a Monday; dates are agreed individually	Start date planned around the date you request and the department's capacity

Before you apply

The programme is delivered in English and every applicant evidences their level with an official document.
Fees and terms are confirmed in writing after the eligibility review; they are not published on this page.
Apply three to six months ahead: departments accept only one or two observers at a time and files are reviewed in order.
State your focus in the objectives of your application. Allocation follows the department's lists during your dates.

What do candidates ask about Colorectal Surgery?

Can I request minimally invasive colorectal exposure?

Yes. Minimally invasive colorectal resection is named in the general surgery department's scope, so it can be named in your objectives and weighted in your allocation where the theatre schedule permits. Which operations fall in your dates depends on the theatre programme, and open surgery remains part of the same lists. Robotic colorectal surgery is a different matter: it does not appear in the published scope and is followed only where the department performs it during your dates — confirmed after review. A placement follows the department, not one surgeon.

Will the placement include multidisciplinary meetings?

Yes. Observers attend the general surgery department's tumour boards and its morbidity and mortality meeting as part of the placement. Where colorectal cancers are on the agenda during your dates, you follow how MRI and CT staging, histology and the patient's fitness are brought together to decide between surgery, neoadjuvant treatment or, for selected rectal cancers, a non-operative approach. Observers are briefed in English by the supervising team and keep anonymised notes, without presenting patients or voting on management.

Does the placement cover colorectal liver metastases?

Partly. Sequencing bowel and liver surgery for synchronous metastases is a joint decision, so the colorectal team's part of that discussion falls within this focus. The liver resection itself belongs to the hepatopancreatobiliary surgery focus within the same general surgery department. If both matter to you, state them in your objectives; because both sit in one department, the allocation can reflect your interests where the schedule allows, but neither type of case can be promised in a given window.

Will I follow surgery for inflammatory bowel disease?

Possibly. Surgery for ulcerative colitis or Crohn's disease is not named separately in the general surgery scope, although colorectal resections are, and the gastroenterology department runs its own inflammatory bowel disease clinic. Operations such as colectomy for acute severe colitis or ileocaecal resection for Crohn's disease are therefore followed where they fall on the colorectal lists during your dates. Surgical decisions in inflammatory bowel disease are usually shared between surgeons and gastroenterologists, which is worth stating in your objectives if this is your interest.
