COMPLICATIONS OF SURGERY FOR PEPTIC ULCER
33
-
Early Complications7% incidence of major complications
and a 1.5% mortality rateBleeding, infection, and
thromboembolism are potential complications after any abdominal procedure.
34
-
Early ComplicationsLeak Acute afferent limb obstruction with
potential duodenal stump leak after Billroth II reconstructions remains a feared complication
35
-
Dumping syndromeRapid emptying from the stomach Early
Late
It consists of a group of cardiovascular and gastrointestinal symptoms: faintness, sweating, tachycardia, bloating,
nausea, and cramping abdominal pain.
36
-
Early dumpingGastric emptying is normally regulated by
duodenal osmoreceptors, but if the pylorus is divided or bypassed, hypertonic fluids can be 'dumped' into the upper small intestine. This leads to an outpouring of fluid into the small intestine to dilute the bowel contents, thereby reducing the blood volume.
Whether or not a particular patient experiences cardiovascular symptoms may depend on how sensitive he/she is to slight changes in plasma volume.
37
-
Early dumpingGastrointestinal symptoms are due to the
sudden release of gastrointestinal peptides such as cholecystokinin and motilin. Symptoms severe enough to interfere with normal activity 5% per cent after vagotomy and drainage or partial gastrectomy, 10% -milder symptoms.
Symptoms tend to improve with the time.
38
-
Early dumping Vasomotor and gastrointestinal
symptoms which typically occur 15 to 30 minutes after eating:
dizziness,
flushing,
nausea
39
-
Early dumping - treatmentDietary - avoiding high-osmotic foods
and separating drinking and eating.Octreotide acetate is generally
effective in treating severe dumping symptoms that have not responded to appropriate dietary alterations.
40
-
Late dumpingHypoglycaemia occurring about 2 h after a
meal because of a large initial secretion of insulin in response to the high sugar load.
Less common than early dumping.Same management like early dumping However, the patient can also carry a
glucose sweet, which can be taken as soon as the symptoms start, to prevent a severe hypoglycaemia
41
-
Dumping syndrome surgical treatmentIf the patient has a gastroenterostomy
and a patent, intact pylorus, then just taking down the gastroenterostomy will probably solve the problem.
Reversed jejunal segment Roux-en-Y gastrojejunostomy has been reported to achieve relief of dumping symptoms in 65% of the most severe cases.

Postvagotomy diarrhoeaSevere diarrhoea may affect 10 % of
patients after truncal vagotomy and drainage, but only 1% after proximal gastric vagotomy.
Loperamide or diphenoxylate/atropine are required for adequate relief.

After Yamada T. Textbook of gastroenterology
-
Afferent limb syndromeAfter Billroth II gastrojejunostomyCause - the limb of duodenum and jejunum
responsible for proximal intestinal, biliary, and pancreatic drainage becomes partially or completely obstructed proximal to the gastric anastomosis.
Two forms: Acute
chronic
47
-
Acute afferent limb syndromeObstruction of the afferent limb leads
to accumulation of secretions within the proximal jejunal lumen. As lumenal pressure increases, venous pressures are quickly exceeded, resulting in ischemia and pressure necrosis of the intestinal mucosa.
Disruption of the duodenal stump may result.
48
-
Acute afferent limb syndromeIs a surgical emergency.Mortality rates associated with acute
afferent limb syndrome approach 50%
49
-
Chronic afferent limb syndrome
It results from intermittent, partial mechanical obstruction of the afferent limb.
Symptoms: postprandial epigastric discomfort, pain, and fullness and, later bilious vomiting, usually void of foodstuff.
Treatment remedial surgery
50
-
Chronic afferent limb syndrome - treatmentConversion to a Roux-en-Y
gastrojejunostomy Alternatively, a Braun
enteroenterostomy between the afferent and efferent limbs is effective in decompressing the obstructed afferent limb.
51
-
52
After Yamada T. Textbook of gastroenterology
-
Efferent limb syndromeIn patients treated with Billroth II
gastrectomy, obstruction of the gastrojejunostomy distal to the anastomosis is termed the efferent limb syndrome.
The causes of obstruction include postoperative adhesions, internal herniation, and jejunogastric intussusception.
53
-
Efferent limb syndromeColicky abdominal pain, distension, diffuse
tenderness, and frequent bilious emesis. The diagnosis is confirmed by either barium
swallow or computed tomography scan with oral contrast.
Upper endoscopy should be performed when recurrent ulcer, gastric stump carcinoma, or intussusception are suspected.
54
-
Alkaline reflux gastritisNausea, burning epigastric pain,
bilious vomiting, and weight loss because of reflux of bile and pancreatic juice.
Prokinetic drugs are useful metoclopramide
55
-
Alkaline reflux gastritisRevisional surgery Only in significant reflux disease
Pyloric reconstruction or the closure of a gastrojejunostomy are the first surgical measures if there has been no resection.
After a Polya (Billroth II) gastrectomy, a Roux-en-Y reconstruction or Tanner Roux procedure

-
Delayed gastric emptyingDelayed gastric emptying of solids can coexist with
rapid emptying of liquids and persists in a few patients long after the early postoperative period.
After vagotomy, especially if there has been some obstruction of the antral outlet.
Patients, therefore, are advised to keep their meals as dry as possible and drink between meals, and to bite their meals up well.
59
-
Delayed gastric emptyingProkinetic drugs are helpful, for
example metoclopramide or erythromycin have even been found to give some benefit on the gastric remnant when the antrum has been removed.
60
-
Stomal ulcerCause: H. pylori infection
Billroth II gastrojejunostomy
Completeness of previous vagotomy
Unsuspected gastrinoma (rare)
61
-
Nutritional problemsLoss of weight Iron, folate and vitamin B12 deficiency Hypocalcaemia and malabsorption of fat
and fat-soluble vitamins, especially when the duodenum is bypassed and the mixing of food with bile and pancreatic secretion is poor because of persistent diarrhoea as steatorrhoea

Gastric remnant carcinoma1-4% incidenceTwenty years after a gastric resection for benign
disease, a patient has a 3.7-fold increased risk of developing carcinoma of the gastric remnant
More than 10-20 years to appearPossible causative factors hypochlorhydria,
alkaline reflux,
diminished gastrin production,
uneradicated H pylori infection
nitrosation
64
-
Gastric remnant carcinomaPatients undergoing antrectomy with
Billroth II reconstruction appear to have a two to sixfold increased risk of developing gastric remnant carcinoma.
Patients with gastric remnant carcinomas tend to present late in their course, with more advanced disease, and tend to be elderly.
65
-
Gastric remnant carcinomaGastric remnant carcinoma usually
requires completion gastrectomy with Roux-en-Y reconstruction.
