(e.g., vagina, bladder) incorporated into the staple line and make sure the proximal
purse string remains intact (Fig.18.2c). Once the stapler is red and extracted, the
anastomotic doughnuts should be inspected for completeness. A complete doughnut
is intact circumferentially and includes all layers of the bowel wall– mucosa, muscularis, and serosa. The nal step in creating a secure anastomosis involves assessing
that the anastomosis is airtight and intact, which will be discussed below.

End toSide Anastomosis
An end to side anastomosis is variation of an end to end that does not require the
placement of a purse string. It can be used for any level of rectal anastomosis. For
this technique, the colon is divided sharply, and the colotomy is opened. The anvil
is passed into the lumen via the end colotomy (Fig. 18.3a). The spike is then
brought out through the antimesenteric wall roughly 3–4 cm proximal to the
colotomy and secured in position with a clamp (Fig.18.3b). The colotomy is then
re-approximated with Allis clamps and closed with a ring of linear stapler
(Fig.18.3c). It is critical to ensure that the anvil is brought out through the colonic

wall proximal enough to ensure that the linear staple line is not incorporated into
the circular staple line and that there is enough tissue (>2cm) between the circular
and linear staples lines to maintain perfusion to this bridge of tissue. Once the
placement of the anvil is complete, the anastomosis is created using the same
technique as described above.

Colonic J Pouch
Proctectomy with reconstruction has a very profound impact on a patient’s bowel
function. Therefore, surgeons have developed several reservoir or neorectum procedures for anastomosis within 5cm of the anal verge. Utilization of a reservoir above
5cm often results in increased difculties with evacuation. Options for reconstruction after proctectomy include a straight colorectal anastomosis (described under
end to end anastomosis), colonic J pouch, transverse coloplasty, and the Baker anastomosis (described under end to side anastomosis). Functionally, the colonic J
pouch has better immediate outcome, but after 2years all of the types of reconstruction have similar functional outcomes [4]. Using a reservoir for an anastomosis
above 5cm may result in difculties with evacuation. Anastomosis at the pelvic
oor will require division of the inferior mesenteric artery at its origin, division of
the inferior mesenteric vein at the inferior boarder of the pancreas, and complete
mobilization of the splenic exure to ensure adequate length for the proximal colon
to reach the pelvic oor. For the best functional outcomes, it is recommended that
soft, pliable descending colon be used for the anastomosis. Utilization of stiff,
thickened sigmoid colon will result in decreased compliance of the neorectum and
may increase the chances of developing low anterior resection syndrome.
A colonic J pouch is constructed to be 5cm in length. A larger reservoir is associated with evacuation difculties. The colon is divided with a linear stapler, and
staple line may be oversewn to prevent a leak at the tip of the J.A colotomy is made
on the antimesenteric border 5cm proximal to the transecting staple line (Fig.18.4a).
One fork of the stapler is passed up the proximal limb, and the other fork is passed
up the distal limb. The stapler is then reassembled, and the bowel wall is rotated so
that the stapler will re down the antimesenteric boarder of the colon (Fig.18.4b).
It is important to ensure that all epiploic appendages are excluded from the staple
line. Once the stapler is removed, a handsewn purse string in a Connell fashion is
placed at the colotomy. The EEA stapling anvil is placed into the colotomy, and
purse string is cinched down (Fig.18.4c). The anastomosis is then created by passing the stapling device transanally and deploying the spike through the rectal stump.
The anvil is then connected to the stapling cartridge ensuring proper orientation of
the left colon. As the stapler is cinched down, the anterior tissues (prostate and bladder in a male and the vagina in a female) must be elevated and conrmed to be free
of the EEA staple line before ring. Given the complexity of J pouch and the low
anastomosis, most surgeons would recommend proximal diversion.
Transverse Coloplasty
A transverse coloplasty is an acceptable alternative to a colonic J pouch when the
pouch will not t into the pelvis. Reasons that a J pouch will not t into the pelvis
include a bulky mesentery and or a narrow pelvis. Construction of the coloplasty
begins with sharp division of the proximal colon, placement of a purse string, and

securing of an EEA stapling anvil. On the antimesenteric border of the colon and
4cm proximal to the anvil, an 8cm colotomy is created and extended proximally
(Fig.18.5a) The longitudinal colotomy is then closed in a transverse direction in a
handsewn fashion (Fig.18.5b). A 3-0 monolament suture is for the rst layer.
Beginning at one of the corners, a running Connell stitch is used to close the colotomy, and the second layer of imbricating Lembert stitches are placed to reinforce
the suture line (Fig.18.5c). With the coloplasty completed, an end to end anastomosis is completed as previously described.
Baker’s Anastomosis
This is the same anastomosis as that described in the end to side technique. When
constructed as an anastomosis at 5cm or less from the anal verge, functional outcome falls in between that for a colonic J pouch and a transverse coloplasty.
Anastomotic Assessment
Once the anastomosis is created, it must be appropriately assessed to ensure that it
is intact. Proper assessment has three components: (1) inspection of the anastomotic
doughnuts, (2) air leak testing, and (3) direct intraluminal visualization of the

18 Laparoscopic Left andSigmoid Colectomy: Options forColonic andColorectal…
anastomosis. The proximal and distal anastomotic doughnuts should be intact circumferentially with all three layers of the bowel. The management of incomplete
doughnuts is addressed below. Inspection of the anastomosis itself can occur with
either rigid proctoscopy or exible endoscopy. With either technique, the pelvis is
lled with normal saline, and the bowel is manually occluded proximal to the anastomosis. The endoscope is then introduced transanally into the rectum, air is insufated to distend the anastomosis, and the pelvis is examined for the presences of air
bubbles. The management of an anastomosis that is leaking air bubbles is described
below. During or after the air leak test, the endoscope is used to directly evaluate the
anastomosis. The anastomosis is examined for completeness, bleeding, and perfusion. For more details on techniques to assess the integrity and perfusion of leftsided anastomoses, please refer to Chap. 29 on minimizing colorectal anastomotic
leaks.

Pitfalls andTroubleshooting
Unable toPass Stapler totheTop oftheRectal Stump
The longer the rectal stump, the more difcult it can be to get the EEA stapler to
navigate past all of the rectal folds and get the stapler head ush against the transverse staple line. Adhesions or scarring of rectum may make it difcult in which
case further mobilization of the rectum will be benecial. This may require mobilization below the peritoneal reection. The upper rectal folds or a narrowed upper
rectum may also prevent passage of the stapler. The use of EEA sizers may help
atten out the folds or dilate a narrowed rectum because of their oval shape, and this
will help to facilitate the passage of the at or square face of the stapler head. If this
is unsuccessful, then the rectum needs to be divided again at the level to where the
stapler can easily be passed.
Rectal Stump Blowout
A disruption of the transverse staple line on the rectum can be one of the most frustrating situations because it often happens at the end of a long case. Poor tissue
quality, thickened rectum, and traumatic rupture from passing the stapler are all
causes of the rectal staple line falling apart. If this occurs in the upper rectum, it is
easily rectied by dividing the rectum a few centimeters below the previous staple
line. If this is due to a thicken rectum, it may be helpful to use a longer staple height
when stapling across the rectum or dividing the rectum a level where it is the softest.
When the disruption of the staple line occurs in the rectum below the peritoneal
reection, salvaging the rectum becomes much more complicated. The rst step is
to mobilize the rectum to the pelvic oor circumferentially. This will maximize the
chances that another stapler can be red across the rectum. If you are unable to restaple the rectum laparoscopically, conversion with a suprapubic incision is

282
M. G. Mutch
warranted. This will allow the rectal stump to be grasped with clamps and re-stapled
with an open linear stapler. If it is not possible to staple across the rectal stump,
there are two remaining options. The rst option is a handsewn purse string on the
rectal stump. All of the staples must rst be removed. The purse string can be placed
intraabdominally from an open or laparoscopic approach. With the use of a 2-0
monolament suture, a purse string is sewn in a full-thickness Connell fashion. This
can be particularly challenging because of limitations of the laparoscopic instrumentation, and because visualization from an open approach is poor at best. A second option is to place the purse string transanally. With the patient in the lithotomy
position, the legs are frog-legged in the stirrups to expose the anus. The anus in then
everted with Lone Star retractor. An operating anoscopy is passed into the anal
canal, and the purse string is then placed in the same fashion as above. In either the
transabdominal or transanal technique, the stapler is inserted into the rectum, and
the spike is deployed before the purse string is cinched down. The purse string is
then tied around the spike of the stapler, ensuring that the rectal wall is securely and
circumferentially drawn into the stapler. The ultimate fallback for when the rectal
stump cannot be salvaged is a mucosectomy with a handsewn coloanal anastomosis.
This will work for all the described types of reconstruction. Once again, the patient
is placed in high lithotomy position to expose the anal canal. The anal canal is
everted with a Lone Star retractor. If the top of rectal stump is visible and easily
accessed, the staple line is excised, and the anastomosis is created. Otherwise, a
mucosal incision is made circumferentially 1–2cm above the dentate line. The submucosal plane is developed and dissected in a cephalad fashion, and eventually the
dissection becomes full thickness resecting the rest of the rectal stump. The idea is
to preserve as much of the internal sphincter as possible. With the dissection completed, the rst sutures are placed in the rectum at the 12, 3, 6, and 9 o’clock positions. The sutures are placed from inside the lumen to the outside, and the needles
are left on the suture. Next the proximal colon is grasped transanally and delivered
into the anal canal. The sutures are then sutured to the proximal colon in an outside
to inside fashion, so the knots for each suture are inside the lumen. Each quadrant is
then completed with full-thickness, interrupted sutures.
Positive Air Leak Test oftheAnastomosis
The assessment of the anastomosis entails inspection of the anastomotic doughnuts
and air leak testing of the anastomosis as described above. As a result, there are four
different scenarios that can arise (Fig.18.6): (1) complete doughnuts with an airtight anastomosis, (2) complete doughnuts with air leaking from the anastomosis,
(3) incomplete doughnuts with an airtight anastomosis, and (4) incomplete doughnuts with air leaking from the anastomosis. Each component of the scenarios
impacts the management of the anastomosis. The ideal is intact doughnuts with an
airtight anastomosis. However, if the doughnuts are incomplete or there is an air
leak at the anastomosis, this will require further management. The presence of complete doughnuts with an air leaking from the anastomosis is managed based on the

size of the air bubbles leaking and the source can be clearly visualized. Small
“champagne” bubbles for the anterior half of the anastomosis that can be visualized
can be managed by placing Lembert stitches across the anastomosis. The placement
of multiple stitches along the anastomosis is recommended as a single suture is not
adequate. If the small “champagne”-type bubbles cannot be seen, consider proximal
diversion or revision of the anastomosis by taking it down and recreating it. If the
bubbles are large with an obvious defect in the staple line, this needs to be managed
with revision of the anastomosis. However, if the anastomosis is low and can be
accessed transanally, the anastomosis can be repaired transanally with proximal
diversion. When the doughnuts are incomplete with an airtight anastomosis, this
anastomosis should be protected with proximal diversion, or it should be revised
because it cannot be guaranteed that the anastomosis is full thickness. For an anastomosis with incomplete doughnuts and leaking air, it should be taken down and
re-created as proximal diversion alone is unlikely to be sufcient. For more details
on techniques to manage intraoperative air leak and other anastomotic complications, please refer to Chap. 30 on how to salvage the failed anastomosis.
Staple Line Bleeding
With routine use of endoscopic assessment of the anastomosis, it is easy to identify
and manage bleeding from the anastomosis. It is important to use CO2 insufation
so the colon and rectum do not remain distended. If a site of bleeding is identied,
it can be managed with endoscopic clips or injection with epinephrine or coagulated. Caution with epinephrine is needed as to not over-inject, causing issues with
local perfusion and with caution with electrocoagulation as not to cause extensive
thermal injury to the anastomotic tissue. If transanal or endoscopic attempts at controlling the bleeding fails, direct suture ligation of anastomotic bleeding can be

284
achieved using a transanal endoscopic platform (TEM/TAMIS), assuming the anastomosis can be reached.
M. G. Mutch
Inadequate Reach oftheColonic Conduit
Ensuring the proximal colon has adequate reach for a well-perfused and tensionfree anastomosis is critical to ensure proper healing. The rst steps to provide adequate length for the colon to reach the top of the rectal stump include high ligation
of the inferior mesenteric artery at its origin, ligation of the inferior mesenteric vein
adjacent to the ligament of Treitz near the inferior border of the pancreas, and full
mobilization of the splenic exure with division of the attachment to the inferior
border of the pancreas to the midline. If there is still inadequate length to reach the
rectal stump, then additional maneuvers will be required, which will be presented in
a step-wise progression. First, complete mobilization of the transverse colon from
the omentum and the attachments within the lesser sac especially the stomach. This
mobilization should extend to the hepatic exure. Second, the colon may be brought
down the right side of the abdomen and passed through a window on the small
bowel side of the ileocolic pedicle. This is an avascular window, and by bringing the
colon through this window, it is the shortest path and prevents the colon from coursing over the terminal ileum (Fig.18.7). Third, the middle colic vessels can be ligated
in a sequential fashion. If the colon maintains perfusion from one of the remaining
branches of the middle colic vessels, bringing the colon down the right side as
described above is often adequate to reach into the pelvis. Finally, if perfusion to the
distal colon or there is still not enough length, then resection of the distal portion of
the colon to a point where the prefusion to the remaining colon is depend upon the
ileocolic pedicle will be needed. To get adequate length, complete mobilization of
the right colon and the proximal colon can be brought into the pelvic either via the
window in the ileal mesentery described above or with the use of Deloyer’s technique. The Deloyer’s technique involves complete mobilization of the right colon
and its mesentery off the retroperitoneum. The proximal colon is then rotated counterclockwise 180, so the colon is brought down the patient’s right side, and the
cecum ends up in the right upper quadrant (Fig.18.8a, b).
Outcomes
Anastomotic Leak
An anastomotic leak is one of the most dreaded complications associated with
colorectal resections. Its occurrence has signicant impact on the patient’s recovery, bowel function, cancer-related outcomes, and may ultimately result in a permanent stoma. These are multifactorial events, and the literature is full of reports
detailing potential risk factors. The literature has several limitations that impact
our ability to accurately identify true and consistent risk factors such as
