Overview: GastrostomyOverview: Gastrostomy
• The delivery of health care has changed over the past two decades
• More aggressive approach to the placement of tube gastrostomies • Earlier return to home• Transfer to chronic care facility
• Obvious benefits of enteral feeding over parenteral nutrition
Overview: GastrostomyOverview: Gastrostomy
• Open surgical gastrostomies have been supplanted by closed procedures• These procedures are generally safe and effective• Complications are frequent
• Surgeon must be aware of both the options for enteral access and complications related to tube gastrostomies

• patient chewed food and ejected it into feeding tube
• Patient reportedly lived fifteen years
1891: Witzel Gastrostomy1891: Witzel Gastrostomy
• Pursestring suture is placed in anterior stomach
• Incision is made in the stomach
• Tube is passed for 5cm and pursestring secured
• Additional sutures are placed to imbricate the gastric wall
• Stomach is then secured to the abdominal wall
1894: Stamm Gastrostomy1894: Stamm Gastrostomy
• Anterior wall of mid-stomach
• Separate incision in abdominal wall for exit of gastrostomy
• Pursestring suture is placed followed by incision into the stomach
• Feeding tube then inserted into stomach and pursestring secured
• Second pursestring placed to invaginate the first pursestring
• Stomach is then secured to the abdominal wall
Early 1900s: Janeway GastrostomyEarly 1900s: Janeway Gastrostomy
• Mucosa lined permanent gastrostomy
• flap of stomach 5-6 cm in width is made
• Flap is then made into a tube by approximating the edges
• A feeding tube is then advanced into stomach
• the tube is then brought out through abdominal wall
• mucosa sutured to the abdominal skin
Early 1900s: Beck-Jianu GastrostomyEarly 1900s: Beck-Jianu Gastrostomy
• Permanent mucosa lined
• Long gastric tube fashioned from the greater curve
• based on the left gastroepiploic a.
• Gastrocolic ligament and gastrosplenic omentum divided
• stomach is divided longitudinally and sutured
• Tube is then exteriorized and mucosa is secured to skin
• Can use GI stapling device
1939: Glassman’s Gastrostomy1939: Glassman’s Gastrostomy
• Mucosa lined
• leakage of gastric juice prevented by formation of coned shape diverticulum
• anterior wall of stomach grasped with Babcock clamp
• pulled up into cone shape
• pursestring suture placed around base
• second and third pursestring are placed above
• Lambert sutures are then placed to create circular valve
1980: Percutaneous Endoscopic Gastrostomy1980: Percutaneous Endoscopic Gastrostomy
• Gauderer and Ponsky (J. Ped. Surg., 15:872, 1980)
• Gastrostomy without laparotomy• “Pull Technique”
• pre-procedure antibiotic prophylaxis • Intravenous sedation and local anesthesia• Gastroscopy is performed and the stomach insufflated with
air and transilluminated• Site for placement selected and a small 5-8mm incision is
made• Intravenous catheter is quickly introduced through
abdominal and gastric walls and needle removed
Percutaneous Endoscopic Gastrostomy (PEG)Percutaneous Endoscopic Gastrostomy (PEG)
• “Pull Technique”• Guidewire grasped with snare
• Snare, guidewire and gastroscope pulled through mouth
• Commercially available PEG tube is then attached to guidewire
• PEG pulled retrograde through mouth, esophagus, stomach, stomach wall and abdominal wall
• Gastroscope re-inserted to confirm positioning of PEG
• Tension is applied to the PEG to ensure gentle approximation of stomach and abdominal wall
• Outer bolster then applied to secure position

PEG: Rare ComplicationsPEG: Rare Complications
Colocutaneous fistula (Yamazaki et al., Surg Endosc 1999;13:280-282)
• Approx. 11 cases in literature
• Penetration of transverse colon at tube placement
• Excessive tension of tube and tube migration
• 5 of 11 cases previous abdominal surgery

• However, can be treated with tube removal
• Fistula usually closes spontaneously
PEG: Rare ComplicationsSquamous cell carcinoma at PEG site (Ananth and Amin Br J
Oral Max Surg 2002;40:125-130)
• Head and Neck Cancer is a common indication for PEG
• 18 Cases in the literature
• All used “pull method”
• No cases reported using the “introducer method”
• Implantation vs. hematogenous vs. local spread

• Local trauma at gastrosotmy placement may predispose to
hematogenous and lymphatic spread
• Perhaps best to place tube after resection/debulking of
tumour
• Biopsy suspicious granulation tissue around PEG site

PEG and Radiologic GastrostomyPEG and Radiologic GastrostomyOutcomes of surgical, percutaneous endoscopic, and percutaneous
radiologic gastrostomies Cosentini EP, Arch Surg 1998 Oct;133(10):1076-83
Retrospective Review:• 14 patients surgical gastrostomy• 24 patients PEG• 44 Percutaneous radiological gastrastomy
• 1 procedure related death in the radiological group (aspiration followed by multiorgan failure)
• No difference in minor and major complications complications• 3 patients in radiological group needed early laparotomy for tube
dislodgement (2 patients) and tear off of T-bolster (1 patient)
• 10% lower tube function rate in radiological group (16F vs. 22F)
ConclusionsConclusions• Percutaneous Endoscopic Gastrostomy is the most common means
of establishing eneteral nutrition• Can be performed at the bedside
• Minor Complications: 2-36%
• Major Complications: 0-17%
• Percutaneous Radiological Gastrostomy is a reasonable alternative to PEG and may be the procedure of choice when PEG fails
• More difficulty in maintaining tube patency
• Minor Complications: 2.9-33%
• Major Complications: 0-11%
ConclusionsConclusions
• Laparoscopic Gastrostomy alternative to open gastrostomy in patients who are unsuitable for both PEG and PRG
• Minor Complications: 2-19%
• Major Complications: 0-6%
