What and who ?
� Resection of rectosigmoid and formation of colostomy, closure of rectal stump
� In response to high mortality of abdominoperineal resection described in 1908 by Miles ¡ Operative mortality 38% APR compared to 8.8% HP
� First described by French surgeon Henri Albert Hartmann at the 30th congress of the French surgical association in 1921

Indications for a Hartmann’s procedure
� Initially developed for treatment of distal colonic adenocarcinoma
� Currently, for complicated perforated diverticulitis
![Page 4: LIVERPOOL HOSPITAL SURGICAL TEACHING MAY 4TH, 2015175days.com.au/wp-content/uploads/2015/05/Hartmanns.pdf · 2015-05-20 · LIVERPOOL HOSPITAL SURGICAL TEACHING MAY 4TH, 2015 Describe](https://reader031.vdocument.in/reader031/viewer/2022041005/5ea9be91b0ad757f324f7ee5/html5/thumbnails/4.jpg)
Hinchey’s classification of complicated diverticulitis
� Stage I - Diverticulitis with a paracolic abscess � Stage II - Diverticulitis with a more distant abscess
(pelvic or retroperitoneal) � Stage III - Diverticulitis with purulent peritonitis � Stage IV - Diverticulitis with fecal peritonitis

Preop stomal therapy r/v
� Appropriate marking of site can reduce postoperative problems such as leakage, fitting challenges, need for expensive custom pouches, skin irritation and clothing concerns.
� Poor placement can impact emotional well being. � Good placement enhances the likelihood of patient
independence in stoma care with early resumption of normal activities.

� Self retaining retractors ie bookwalter � Pack small bowel in right upper quadrant in warm, moist
sponge � Mobilize left colon, place moist sponge over left colon –
begin by dividing congenital sigmoid adhesions. Avoid traction on Spleen.
� Left colon is retracted anteromedially out of the wound to expose lateral peritoneal attachments
� Full thickness of the peritoneum is incised from sigmoid colon in a cephalad direction

Procedure - continued
� Sigmoid colon retracted medially to place V shaped mesocolon on a stretch
� Peritoneum at the apex is entered and the extrafascial plane between left mesocolon and Gerota’s fascia is developed
� Identify gonadal vessels and left ureter � Ureter seen as it crosses over the common iliac
vessels – confirm by demonstrating vermiculation with DeBakey forceps, non pulsatile ¡ Passes on the psoas major in the retroperitoneum

Procedure - continued
� Distally, a linear stapler or curved contour stapler can be used for the rectum

◆ Using forceps clamps and 3-0 silk ligatures, incise the colonic mesentery from the colos-tomy site at a suffi cient distance so that the two ends of the severed colon can be retracted through the abdominal wall.
◆ Grasp the skin at the site chosen for colostomy, usually just lateral to the rectus abdominis muscle in the right or left lower quadrants, retract the skin, and incise with scalpel or elec-trocautery, creating a circular opening (Figure 54-3).
◆ Use electrocautery to make a cruciate incision through the abdominal wall and perito-neum (Figure 54-4).
◆ Manually insert at least two fi ngers through the colostomy site.

Procedure - continued
� With cutting diathermy or scalpel, make cruciate incision through fascia without cutting through muscle
� Using straight Mayo scissors, separate muscle fibres by spreading blades
� Use retractor to keep the fibers separated and make cruciate incision in posterior sheath with cutting diathermy
� Preserve inferior epigastric vessels � Defect should allow two fingers to go through � Babcock on stapled edge, pull colon through (check
orientation, ensure no twists) 3cm above skin

◆ Complete any further procedures within the abdomen, irrigate copiously, and then close the midline abdominal incision.
◆ Cover the midline wound with antiseptic-impregnated gauze.
◆ Use electrocautery to excise the stapled end of the colon, leaving 2 cm exteriorized from the abdominal wall. Use 4-0 Vicryl sutures or judicious electrocautery to secure hemosta-sis along the bowel end (Figure 54-7).

C H A P T E R 54 • Diverting End Colostomy with Mucous Fistula or Hartmann’s Pouch 625
◆ Use several 3-0 Vicryl sutures in simple, interrupted fashion to circumferentially secure edges of the colostomy to skin (Figures 54-8 and 54-9).
◆ If you have a concern that the distal colonic segment is obstructed, creating a closed-loop obstruction, exteriorize the distal colonic segment in the same manner as the end colos-tomy, which creates a mucous fi stula.
Sutures loop through skin,bowel wall close to edge, then out of edge to invertcolon wall only slightlyover skin surface
