One hundred patients underwent laparotomy for independent jejunal feeding tube placement. Neurologic disease was present in 50%, and obtundation (28) and oropharyngeal dysmotility (25) were the most common indications for enteral feeding. The post-pyloric route was chosen because of aspiration risk in almost all (94%) patients. Postoperative (30-day) mortality rate was 21%, because of cardiopulmonary failure in most (18). One death resulted directly from aspiration of tube feeds. Two surgical complications required reoperation: one wound dehiscence and one small bowel obstruction. Four wound infections occurred. Two patients underwent reoperation after tube removal, and four tubes required fluoroscopically guided reinsertion for peritubular drainage (2), removal (1), and occlusion (1). Aspiration pneumonia was present in 18 patients preoperatively and in eight postoperatively. None of the patients with feeding-related preoperative aspiration pneumonia (13) had a recurrence while fed by jejunostomy. Three patients developed postoperative aspiration pneumonia before initiation of jejunostomy feedings. Jejunostomy may be performed with low morbidity rate and substantial reduction of feeding-related aspiration pneumonia, and is the feeding route of choice in aspiration risk patients.

Clostridia rarely cause pleuropulmonary infections in the absence of trauma. We report a case of intermittent bowel obstruction, clostridial bacteraemia and pneumonia with a fatal outcome. Only 16 cases have previously been reported. Clostridial infection of the lung has many features of an acute pneumonia and is almost always associated with a pleural effusion. Most cases are caused by Clostridium perfringens, though infections with other species have been reported. The prognosis is generally more favourable than in clostridial infection secondary to aspiration pneumonia or complicating empyema.

In a 6.5 year period starting January 1982, 121 patients (74 male, 47 female; 1.6:1) with complicated gastroesophageal reflux referred to Alberta Children's Hospital, University of Calgary, required a Nissen fundoplication at a mean age of 35.5 months (range 3 weeks to 18 years). The median age of onset of symptoms was less than 1 month. Symptoms and indications for surgery included regurgitation (88%), failure to thrive (52%), reflux-associated pulmonary symptoms and aspiration (48%), biopsy evidence of esophagitis (35%) with heartburn (17%), dysphagia (18%), hematemesis (17%), anemia (13%), and hypoproteinemia (22%). Sixty-four percent of the patients had a syndrome or chromosomal abnormality, respiratory disease, or neuromuscular disorder. The barium contrast upper-gastrointestinal radiographic series, performed in all patients, identified structural [gastric outlet obstruction (2%), esophageal stricture (11%), erosive esophagitis (9%)], and functional abnormalities [gastroesophageal reflux (90%), barium aspiration (8%), esophageal hypoperistalsis (30%), delayed gastric emptying (4%)]. Barium contrast upper gastrointestinal radiographic series identified gastroesophageal reflux with a sensitivity of 90% (compared to history), was 50% sensitive and 92% specific for erosive esophagitis (compared to biopsy), was 59% sensitive and 74% specific for esophageal dysmotility (compared to esophageal manometry), and there was a significant (p less than 0.01) association between barium aspiration and prior evidence of aspiration pneumonitis. Esophageal manometry demonstrated a significantly (p less than 0.001) lower esophageal sphincter pressure in patients compared with controls, but no significant correlation with failure to thrive, aspiration pneumonia, biopsy evidence of esophagitis, or parameters of the 24-hour esophageal pH study. Twenty-four hour pH monitoring showed significantly (p less than 0.05) more reflux episodes than in asymptomatic controls and there was significant (p less than 0.05) correlation between the percentage of time pH was less than 4 and the presence of hypoalbuminemia, and biopsy-proven erosive esophagitis or Barrett's esophagus. Endoscopic appearance was 91% sensitive and 60% specific for esophagitis when compared to biopsy. Nissen fundoplication was completely effective at resolving gastroesophageal reflux in 83%, and associated with marked improvement in 15%. No patient died as a result of fundoplication. Major complications included: recurrence of symptoms requiring reoperation (2%), subsequent mechanical bowel obstruction (8%), wound infection or pneumonia (12%).

This report reviews the clinical and radiographic features of 40 patients who underwent visceral esophageal substitution with colon for benign or malignant lesions of the esophagus. The incidence and radiographic identification of complications are discussed. All patients were routinely examined with barium esophagrams on postoperative day 10. If an anastomotic leak was suspected clinically before this time, studies were performed using water-soluble iodinated contrast material. Follow-up barium esophagrams were obtained 1-96 months after operation (average, 60 months) in 24 patients. Eight patients (21%) demonstrated asymptomatic "jejunization" of the colonic mucosa with no attributable clinical manifestations; this finding resolved in 1-3 months, without sequelae, and has not been reported before. The spectrum of ischemic changes in the colonic segment included mucosal edema, spasm, ulceration, loss of haustration, and frank necrosis. Radiographically detectable early postoperative complications included anastomotic leak in six (three pharyngocolic, three cervical esophagocolic) and aspiration of barium into the tracheobronchial tree due to incoordinated swallowing in eight. Late postoperative complications included anastomotic narrowing (12) malfunctioning of the colon due to impaired emptying (five), recurrent aspiration pneumonia (three), small bowel obstruction (three), transhiatal herniation of small bowel through the diaphragmatic hiatus (one), and reflux into the retained bypassed esophagus (one).

The initial experience in laparoscopic transabdominal preperitoneal mesh (TAPP) repairs is reviewed. In this study, consecutive TAPP repairs were performed in 126 patients. There were no intraoperative complications, and only 1 procedure had to be converted to open surgery. Forty-six patients had direct inguinal hernias, 56 had indirect inguinal hernias, and 24 had both, of which 21 were recurrent. Fifty-one hernias were right sided, 46 were left sided, and 29 were bilaterals. The male/female ratio was 116:10, and the mean age of the patients was 49.8 (range 17-76). Minor complications included parasthesia over the distribution of the lateral cutaneous nerve of the thigh in 2 patients, hydrocoeles in 2 patients, hematomata in 6 patients, and testicular pain in 4 patients, all of which resolved on conservative management. Incomplete bowel obstruction has been the only major postoperative complication to date, where an area of bowel herniated between two staples in the peritoneum. This was further complicated by an aspiration pneumonia and death of the patient. The mean hospital stay was 1.2 days (range 1-3), and the mean return to unrestricted activity was 8 days (range 3-12). There have been 2 true recurrences to date. One patient had a tender swelling after the repair, which was thought to be a recurrent strangulated hernia. On investigation, it was found to be a hematoma. The mean follow-up has been 7 months (range 1-18). Although early results of the TAPP repair are encouraging, we have had 1 significant complication that may have been avoided if an endoscopic extraperitoneal approach was employed.

A total of 25 patients at least 75 years old underwent continent urinary diversion via a modified Indiana Pouch during a 68-month period, 21 of these with simultaneous radical cystectomy or anterior exenteration. The preoperative medical conditions as well as the early and late operative morbidity and mortality are reviewed with a mean follow up of 27 months. Average age of patients was 78.5 years, and the mean age of survivors is 81 years. There were two early mortalities attributed to ileal gangrene with secondary sepsis and aspiration pneumonia. Postoperative complications (superficial wound infection, middle colic vein bleed, right ureteral leak, ileus) occurred in five patients, two of whom required re-operation. Mean hospital stay was 12.4 days and ranged from 9-20. There were only six late complications [ureteral stricture (3), small bowel obstruction (1), incontinence (1)] necessitating re-hospitalization and surgical intervention. Late infectious complications included recurrent urinary tract infections (3), pyelonephritis (2), and C. Difficile enterocolitis (2) all managed medically. In addition, 10 other patients have died, 9 from metastatic disease and 1 from intercurrent medical problems. Of the 13 remaining patients, 11 are disease free and all are continent with a mean follow-up time of 33 months. We conclude that continent urinary diversion via a modified Indiana pouch with radical cystectomy or anterior exenteration can be performed with minimal morbidity or mortality, even in an elderly population.

We report a right-handed 62-year-old man with early onset familial parkinsonism. The patient was well until 24 years of the age when he noted an onset of resting tremor in his right hand. During the next four years, he noted rigidity, bradykinesia, and difficulty in walking. He was seen in another hospital at 28 years of the age, where he received left pallidotomy. Rigidity on the left side showed marked improvement. He received right pallidotomy at age 30 years. He developed right hemiplegia after this surgery. He was admitted to our hospital in March, 1983 when he was 51 years of the age. He was treated with levodopa but improvement was rather of minor degree. He was transferred to another hospital, but his motor disturbance progressed slowly, and was admitted again to our hospital in November 1990. He had 6 siblings 4 of whom including himself suffered from parkinsonism. No consanguinity was noted in parents. On admission, he appeared chronically ill but the general physical examination was unremarkable. Neurologic examination revealed an alert and mentally sound man. Hasegawa dementia scale was 28.5/32.5. Upward gaze was slightly restricted (3/5). Cranial nerve examination revealed oculogyric crisis, apraxia of eyelid opening, masked face, and small voice. He was able to stand with support; his posture showed left-ward leaning. He had right hemiparesis with moderate weakness. He showed marked bradykinesia and moderate rigidity in his left upper extremity. Fine postural tremor was noted in the left hand. Deep tendon reflexes were diminished in the upper extremities. No Babinski sign was noted. Pain sensation was somewhat diminished on the right side. Results of routine laboratory examination were unremarkable. Cranial CT scan revealed atrophy in the frontal lobe, particularly in the prefrontal area. In addition, MRI revealed T1-and-T2-low signal intensity lesions in the right ventral pallidal region and in the left ventrolateral thalamic-hypothalamic areas. He was treated with 600 mg of levodopa with benserazide and 22.5 mg of bromocriptine with mild to moderate improvement in his bradykinesia and rigidity. He was discharged in January 1991. His clinical course was complicated by intestinal obstruction in October, 1994. He was admitted to another hospital where he was operated on the obstruction on November 5, 1994. The sigmoid colon was markedly dilated but no mass was found. Postoperative course was uneventful until November 18, 1994 when he was found dead in his hospital room shortly after 4 am. The patient was discussed in neurological CPC, and the chief discussant arrived at the conclusion that the patient had young-onset familial Lewy body-negative parkinsonism. Opinions were divided between Lewy body-positive familial Parkinson's disease and Lewy body negative young onset parkinsonism. Postmortem examination revealed aspiration pneumonia, which appeared to be the cause of his death, in the right lung. Neuropathologic examination revealed loss of malanized neurons in the substantia nigra and the locus coeruleus. In the substantia nigra, neuronal loss was particularly severe in the ventrolateral area. No Lewy bodies were seen. The dorsal motor nucleus of the vagal nerve was well preserved. Stereotaxic lesions involved bilateral thalamic areas. This patient appears to represent a case of autosomal recessive juvenile parkinsonism (AR-JP). Early onset, superb response to levodopa, sleep effect, and easy development of dyskinesias and motor fluctuations characterize AR-JP. The reason why this patient did not show these clinical features is probably bilateral sterotaxic surgeries. Particularly, the second surgery was complicated by right hemiparesis. His siblings who developed parkinsonism showed typical clinical features of AR-JP.

Left ventricular assist devices effectively improve hemodynamic function and reverse renal and hepatic dysfunction; however, their effects upon the gastrointestinal (Gl) system have not been addressed. We evaluated Gl function in 27 left ventricular assist device recipients using interviews, Gl contrast studies, endoscopy, and 99mTc sulfur colloid studies of esophageal transit and gastric emptying. While on left ventricular assist device support (mean duration of 84 days), 19 patients reported early satiety and/or nausea, and 1 was unable to tolerate oral intake. Esophageal transit time (normal, < 10 sec) was borderline slow at 14 +/- 4 (mean +/- standard error of the mean) and gastric emptying (normal < 90 min) was prolonged (range of 106-506 min, mean = 283 +/- 69 min). In a 1-38 month follow-up, gastric function subjectively improved in all. Six patients had intraperitoneal device placement. One died of aspiration pneumonia secondary to small bowel obstruction, and one had prolonged inability to tolerate oral intake, which required feeding jejunostomy tube placement. The 21 patients with pre peritoneal placement of the device did not require Gl operative interventions and had no catastrophic Gl events; they had mild to no Gl complaints. Pre peritoneal placement may mitigate early satiety and obviate serious Gl complications.

We reviewed 36 cases of neonatal intestinal obstruction admitted to our surgical unit over a 10-year period, 1986-1996, for surgical intervention following the failure of conservative treatment. There were more males than females and the age range was 12 hours-26 days. Imperforate anus was the main cause of the obstruction (27.8%) followed by duodenal atresia (13.9%) and colonic atresia and meconium ileus (11.1% each). There were 8 deaths following surgery (22% mortality rate), the main causes being aspiration pneumonia, septicaemia and hypothermia.

Non-operative management by pressure reduction is now the preferred treatment for uncomplicated intussusception in children. However, in many developing countries, laparotomy is routinely performed for such cases. This is a retrospective anlaysis of 24 children who had operative reduction of intussusception. The age range was 3 months--10 years (median 7 months) and duration of symptoms 12 hours--7 days (median 2 days). The main features were abdominal pain, vomiting and rectal bleeding. Ten (42%) patients had varying degrees of dehydration, which were corrected. At laparotomy, the intussusceptions were reduced without difficulty. Thirteen (54%) patients developed 15 procedure related complications including wound infection 6(25%), ileus 2(8%), stitch sinus 2(8%), incisional hernia 2(8%), intestinal obstruction from adhesions resulting in intestinal gangrene 2(8%) and aspiration pneumonia 1 (4%). Mortality was 2( 8%) from aspiration pneumonia and overwhelming infection due to intestinal gangrene from adhesive intestinal obstruction respectively. Laparotomy for uncomplicated intussusception in children is attended by significant morbidity and mortality. Many of such intususceptions, may be successfully managed by pressure reduction and children should not be denied the benefits of this form of treatment.
