Right esophageal lung in a preterm child with VACTERL association and Mayer-Rokitansky-Kuster-Hauser syndrome.

We report on a preterm girl (birth weight 1,200 g) with a right esophageal lung in esophageal atresia type VIag (according to the extended classification of Kluth). Additionally, the child suffered from an atrioseptal defect, a dextrocardia with a left descending aorta, a duodenal atresia, a high type of anal atresia (VACTERL association), agenesis of the left kidney, and agenesis of the vagina, uterus, and ovarian tubes (Mayer-Rokitansky-Kuster-Hauser syndrome or incomplete MURCS association). The child was treated with an emergency gastrostomy because of increasing abdominal dilatation. Thereafter, the parents refused further surgical treatment, and the child was maintained on basic therapy. After an uneventful period of 4 weeks, the child died of an acute massive aspiration. This case shows that sufficient spontaneous ventilation is possible in esophageal lung as long as a gastrostomy is kept on suction to prevent overinflation of the affected lung and the stomach. Ethical aspects have to be considered when treatment is planned in cases of prematurity and associated malformations when a chance of good survival is rather limited. The stepwise approach as proposed in the present case appears to be the only possible therapeutic regimen that can be offered in this complicated condition.

Late toxicities and complications in three-year survivors of small cell lung cancer.

123 patients with small cell lung cancer (SCLC) presented to the National Cancer Center Hospital (Tokyo) between 1978 and 1986. 22 of 71 patients with limited stage disease (LD) and none of 52 patients with extensive disease (ED) survived for 3 years. 15 of the 22 three year survivors had significant late complications. All patients received chemotherapy and either thoracic irradiation, resection or both. No prophylactic cranial irradiation was given. 4 patients developed cardiac failure, 2 with a dilated cardiomyopathy, despite the fact that no patient received over 420 mg/m2 of doxorubicin. 12 patients of the 17 who received thoracic irradiation developed radiation pneumonitis and 3 required hospitalisation for severe haemoptysis (2) or cavity formation (1). 1 patient who received nimustine developed a fatal myelodysplastic syndrome and 2 additional patients developed second primary tumours in the oesophagus (1) and stomach (1). Mild peripheral neuropathy (WHO grade 1) was persistent in 3 patients and asymptomatic azotemia (WHO grade 1) in 7. Despite advances in the treatment of SCLC there are very few asymptomatic long-term survivors.

[Gastric pouch dilatation: complications after laparoscopic implantation of a silicone gastric band in pathologic obesity].

In 20 patients with morbid obesity a laparoscopic silicon gastric banding was installed using a LAP-BAND. All patients were examined postoperatively with water-soluble oral contrast material according to the usual protocol. 8 weeks after the operation a second control with thickened barium sulfate was added to measure and adjust the width of the silicon band. There were no early postoperative complications. But in the follow-up three patients presented with a pathologic gastric pouch-dilatation. This severe complication, which can have different etiologies, requires early detection and specific therapy.

Laparoscopic adjustable gastric banding.

The introduction of laparoscopic adjustable silicone gastric banding (LASGB) has recently revolutionized gastric restrictive procedures in the treatment of morbid obesity. We analysed the short and long term results of this minimally invasive bariatric procedure. A total of 652 patients with a body mass of (median) 45 kg/m(2) were treated. There were only minor preoperative incidents. One patient died more than one month after the procedure. Early postoperative complications included 2 gastric perforations caused by a nasogastric tube and one early slipping of the band. Late complications occurred in 7% of the patients: 25 patients suffered a pouch dilation, 2 patients had gastric erosion by the band; 18 patients had port complications requiring reoperation. Loss of excess weight was 62% at 2 years. Laparoscopic adjustable gastric banding is a safe and effective treatment for morbid obesity. The most frequent complication is pouch dilation. Further study is warranted for the evaluation of long term results.

Is endoscopic paravascular injection of sclerosing agents reasonable in the control of GI bleeding?

BACKGROUND: The pharmacologic response and microvascular effects associated with the endoscopic injection of sclerosing agents around vessels (paravascular injection) to stop bleeding from the digestive tract remain to be clarified. METHODS: Using in vivo microscopy, we directly visualized submucosal microvessels of the rat stomach and intestine. We studied differences among sclerosing agents in thrombus formation and vascular diameter change that occur through a pharmacologic response and/or local compression after topical application or paravascular injection of the agents. RESULTS: Except for absolute ethanol, topical application of the agents did not cause constriction or thrombi in either arterioles or venules. Polidocanol topical application and paravascular injection significantly dilated arterioles. Injecting ethanolamine oleate near venules constricted them the longest and most effectively, but vasoconstriction in arterioles was transient. Injecting absolute ethanol formed long-lasting thrombi and caused vasoconstriction in venules, but arteriole thrombi persisted no more than 3 minutes. The vascular response to thrombin did not significantly differ from that to physiologic saline. CONCLUSION: The paravascular injection of ethanolamine oleate, because of its long-lasting vasoconstriction, or of absolute ethanol, because of its thrombogenic effect, is a valid therapeutic approach to treating venous bleeding. The efficacy of paravascular injection of sclerosing agents for treating acute arterial bleeding, however, is not supported in this experimental model.

Gastric stump carcinoma following Billroth II resection for peptic ulcer disease. Comparison with cancer in non-operated stomach.

40 gastric stump carcinomas have been investigated. The results are compared with 72 gastric carcinomas without preceding Billroth II resection. The aim of this study was to contribute to our knowledge about the pathogenesis of gastric stump carcinoma. The mean age of patients with gastric stump carcinoma and with carcinoma without preceding Billroth II resection is identical. The age distribution, too, is similar in both groups. Furthermore the time of the Billroth II resection for benign peptic ulcer shows no correlation with the appearance of the gastric stump carcinoma, which suggests that there is no constant time lag between Billroth II resection and stump carcinoma. The histological investigation of the tumor-free gastric mucosa shows similar alterations in the two groups compared. Intestinal metaplasia and cystic dilatation seems to be more common in the gastric mucosa after Billroth II resection as compared with the non-tumorous mucosa of patients without preceding Billroth II resection. But the grade of nuclear atypia in non-tumorous mucosa is identical in both groups. Interestingly enough, the frequency of the main types of gastric cancer, intestinal carcinoma and diffusely infiltrating carcinoma is very similar. Thus, both the epidemiological and histological data seem to indicate that the pathogenesis of gastric carcinoma is very similar to that of gastric carcinoma without preceding gastric surgery. The Billroth II resection does not seem to be a main factor in pathogenesis, but may have co-factorial significance.

Preliminary clinical application of contrast-enhanced MR portography.

The clinical application of contrast enhanced (CE) MR was evaluated. A total of 66 CE MR portograms were obtained by performing fast imaging with steady procession (FISP) technique on a 1.5-T Siemens magnetom vision. A maximum intensity projection algorithm was also employed to include all vessels in a single image. The patency of portal venous system, the presence and extent of varices were also evaluated. The results showed that all images had diagnostic quality. Main portal vein (MPV) and its 4th-6th level intrahepatic branches were visualized in 10 normal persons serving as control. The diameter of MPV, splenic vein and superior mesenteric vein was 1.02 +/- 0.21, 0.8 +/- 0.15, 0.8 +/- 0.26 cm respectively, which were significantly lower than that in portal hypertension patients (1.38 +/- 0.27, 1.26 +/- 0.18, 1.24 +/- 0.18 cm, respectively). In 23 preoperative cases of portal hypertension, dilated portal vein and tortuous enlarged splenic vein were found in 23 cases; esophageal and coronary varices in 12 and 19 cases, respectively. In 7 postoperative re-examined cases with portal hypertension, the flow velocity and flow of MPV were decreased in all cases and esophageal varices could still be observed in 3 cases. New vessels appeared in the great curvature of stomach in 2 cases. In 20 cases of liver carcinoma, occlusion of MPV or its intrahepatic branches were showed in 14, compression and dislocation of intrahepatic portal vein were found in 6. In other 6 cases, 2 were splenic venous thrombosis and 4 were tumors in the intestine or retro-peritoneum. It is concluded that three-dimensional CE MR portography is an accurate technique for evaluating the portal venous system. It is a reliable and noninvasive technique that can provide important information for the evaluation of patients' condition before TIPSS and liver transplantation.

A prospective randomized trial of different laparoscopic gastric banding techniques for morbid obesity.

BACKGROUND: Slippage of the stomach is the most common postoperative complication after laparoscopic adjustable silicone gastric banding (LASGB) for morbid obesity. Retrogastric placement (RGP) of the band through the lesser sac can cause posterior slippage Incomplete suturing often is responsible for anterior slippage. A randomized prospective study was constructed to determine whether laparoscopic esophagogastric placement (EGP) is associated with a lower incidence of postoperative slippage and pouch dilation than RGP. METHODS: Morbid obese patients presenting for LASGB were randomized to undergo either an EGP (n = 50) or an RGP (n = 51). Patients were blinded to which procedure they underwent, and follow-up date were obtained by a blinded independent investigator. Standardized clinical and radiologic controls were used to assess pouch enlargement and slippage. RESULTS: Operating time was similar for the two procedures (54.5 min for EGP vs 58 min for RGP). There was no significant difference in postoperative weight loss (34 kg after EGP vs 37 kg after RGP within 12 months), esophagus dilation, or postoperative quality of life. There were two postoperative slippages and one pouch dilation in the RGP group and no postoperative complication in the EGP group. CONCLUSIONS: The placement of a LAP-BAND adjustable gastric banding system by the EGP technique is safe and results in a lower frequency of postoperative complications than its placement by the RGP technique. Clear anatomic landmarks are a benefit to education and to the learning curve for LASGB.

Blocking of histamine H2 receptors enhances parietal cell degeneration in the mouse stomach.

The effects of the histamine H2 receptor antagonist, ranitidine, on parietal cell lineage was studied in the mouse stomach by using light and electron microscopy techniques. Mice were continuously infused for 15, 30, and 42 hr with ranitidine. Semithin sections examined under the light microscope revealed spherical light areas in the cytoplasm of parietal cells which in thin sections under the electron microscope appeared to be vacuoles. Cells were categorized as normal, altered and damaged. While altered cells were characterized by dilated canaliculi and vacuoles, the damaged cells showed signs of necrosis or apoptosis. In control mice, altered and damaged parietal cells were consistently few and only found in the pit or base regions of the epithelial units. After 15-hr-treatment with ranitidine, 40% of the parietal cells were altered. After 30 hr infusion, altered parietal cells became 53% of the examined population, and after 42 hr, 72% of the parietal cells were affected (42% altered and 30%, damaged). The gradual increase in parietal cell vacuolation was associated with an increase in the census of pre-parietal cells. Some mice were allowed to recover from treatment for 4 days. The appearance of normal parietal cells and disappearance of damaged cells was observed and the gastric glands became morphologically normal. In conclusion, inhibiting acid secretion by blocking the histamine H2 receptors, enhanced not only the degenerative elimination of parietal cells but also the production of pre-parietal cells and thus, the recovery of the population was prompt.

Chronic subdural hematoma following dural metastasis of gastric cancer: measurement of pre- and postoperative cerebral blood flow with N-isopropyl-p-[123I]iodoamphetamine--case report.

A 58-year-old female with gastric cancer presented with left chronic subdural hematoma (CSH) without history of head injury. Magnetic resonance imaging revealed left CSH with atypical findings such as abnormal dural enhancement and swelling of the left cerebral hemisphere. One month after gastrectomy, motor aphasia and right hemiparesis developed. Irrigation of the left CSH was performed. The hematoma was abnormally mucinous and became solid immediately after irrigation. Histological examination showed that adenocarcinoma cells had metastasized to the dura mater and the outer membrane of the hematoma. The preoperative cerebral blood flow (CBF) in the affected cerebral hemisphere, measured by single photon emission computed tomography using N-isopropyl-p-[123I]iodoamphetamine, was much higher than that in the opposite hemisphere, whereas the postoperative CBF was almost equal in both hemispheres. Subdural hematomas secondary to dural metastases of extraneuronal malignancies are rare, and are usually the chronic type. Measurement of the pre- and postoperative CBF in the present patient with CSH following dural metastasis of the malignant tumor showed that preoperative hyperemia in the affected hemisphere may result from dilation of the cerebral vessels caused by the effects of the CSH.

The elongation of distal esophageal pouch by mechanical bougienage for a year resulted in a tension-free anastomosis in a patient with long gap esophageal atresia: a case report.

Despite the numerous approaches described for the management of neonates with "long gap" esophageal atresia, controversy still exists as to the preferred method. Delayed primary anastomosis is probably the most frequently adopted practice but often the native esophagus is abandoned. We report a case of a 2.98 kg newborn with pure esophageal atresia. Although the elongation of the distal esophageal pouch by mechanical bougienage was initiated at 1 year and 8 months, a successful tension-free anastomosis with minimum dissection of the lower esophagus was performed at 2 years and 7 months. Her postoperative quality of life has been quite excellent. This report emphasizes that a tension-free anastomosis without operating on the lower esophagus and stomach is essential for the treatment of long-gap esophageal atresia.

Gastrointestinal injuries from blunt abdominal trauma in children.

OBJECTIVE: To determine the pattern, presentation and outcome of gastrointestinal injuries from blunt abdominal trauma in children. DESIGN: A retrospective study. SETTING: Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. SUBJECTS: Twenty one children managed for gastrointestinal injuries from blunt trauma from 1984-2002. MAIN OUTCOME MEASURES: The pattern, presentation, management and outcome of gastrointestinal injuries from blunt trauma. RESULTS: In the 19 year period, 1984-2002, 92 children were treated for blunt abdominal trauma, 21(23%) of who had injuries to the gastrointestinal tract. Three presenting after 24 hours had evidence of peritonitis. In six children with isolated gastrointestinal tract (GIT) injury who presented within two hours, abdominal signs were vague at initial evaluation but became marked over a few hours at repeated examination. In eight with associated intraabdominal injuries, abdominal signs were marked at initial examination and five presented with shock. Free peritoneal air was present on plain abdominal and chest radiograph in three of ten patients, dilated bowel loops in six and fluid levels in one. Diagnostic peritoneal lavage or paracentesis was positive in four patients with isolated GIT injuries and eight with associated intraabdominal injuries. There were 24 injuries in the 21 patients consisting of 15 perforations, five contusions, two seromuscular tears, and two gangrene from mesenteric injury. The small intestine was involved in 11 patients, colon six, stomach five, duodenum one and rectum one. Seven (35%) patients had associated extraabdominal injuries. Treatment consisted of simple closure of perforations, over sewing of contusions, resection and anastomosis for gangrene and repair with protective stoma for the rectal injury. One patient each developed prolonged ileus, urinary tract infection and chest infection, respectively postoperatively. Mortality was 28%, all of who had associated intraabdominal or extraabdominal injuries. CONCLUSION: Gastrointestinal injury from blunt abdominal trauma in children, though uncommon, carries a high mortality, usually from associated intraabdominal or extraabdominal injuries.

[X-ray and endoscopic diagnosis of esophageal achalasia].

We evaluated diagnostic X-ray and endoscopic examination findings in 486 patients with esophageal achalasia. Concerning the association between the duration of disease and the X-ray dilatation type, the duration was 1-4 years in more than 50% of patients with the Sp type, a mean of 8.5 years in those with the F type, and frequently more than 10 years in those with the S type. Endoscopy is generally used to determine the presence or absence of abnormal movement. In achalasia, the endoscope can be inserted into the stomach despite resistance at the stenotic site, and the mucosal surface is normal. Squamous cell carcinoma as a complication was observed in 21 patients (4.3%). The carcinoma complication rate was higher with a longer duration of disease and a longer observation period. The mean total course including the postoperative course was 27 years. Long-term and periodic X-ray and endoscopic observation of the disease course is important, and iodine staining is indispensable for early detection of esophageal cancer.

Laparoscopic transhiatal esophagectomy with esophagogastroplasty.

Twelve patients with benign and malignant esophageal diseases were treated by transhiatal esophagectomy, without thoracotomy, using abdominal-mediastinal dissection conducted by videolaparoscopy. A cervical approach was used to retrieve the esophagus and to perform the esophagogastric anastomosis. The procedure was indicated in patients with advanced achalasia of the esophagus, severe reflux stenosis, squamous cell carcinoma, and adenocarcinoma of the esophagus. Three pleural perforations occurred during surgery. Blood loss was minimal. One patient required conversion to open surgery, two patients were submitted to chest drainage, and three had transitory dysphonia. One patient had an anastomotic leak with subsequent stenosis requiring endoscopic dilatation. No mortality occurred in this small series.

[Satisfactory results of conservative treatment in traumatic esophageal perforation].

OBJECTIVE: Evaluation of diagnosis and management of 18 patients with iatrogenic or traumatic oesophageal perforation. DESIGN: Descriptive retrospective. SETTING: University hospital Vrije Universiteit Amsterdam. PATIENTS AND METHODS: In the period 1981-1991 18 patients received conservative treatment for iatrogenic/traumatic oesophageal perforation. RESULTS: The perforation was located in the cervical part of the oesophagus in 13 cases and in the thoracic part in 5 cases. Various incidents had led to the perforation. For radiological examination X-rays of the thorax or lateral neck were made or an oesophagogram using iodine as the contrast medium. Treatment consisted of antibiotics, a stomach catheter, intravenous nutrition and if necessary suction drainage. Seventeen patients recovered completely, one patient died. CONCLUSION: Conservative treatment of iatrogenic oesophageal perforation consisting of antibiotics, stomach catheter, enteric or parenteral nutrition and if necessary suction drainage gives good results.

[Gastroduodenal involvement and circumscribed intestinal stricture in Crohn disease].

Symptomatic gastroduodenal Crohn's disease (CD) is rare although new endoscopic/histologic data indicate a typical focally enhanced gastritis in up to half of all patients with CD. One third of the patients with symptomatic gastroduodenal CD undergo surgery, most of them for (gastro-) duodenal obstruction. Gastroenterostomy with vagotomy is the surgical treatment of choice. Resection, strictureplasty or balloon dilatation can be performed in selected patients. Enterogastric and enteroduodenal fistulas are rare, frequently missed during routine examination and often detected only during laparotomy. Treatment of those fistulas consists of resection of distal bowel (fistula origin) with suture closure of the fistula opening in the stomach/duodenum. Recurrence rate after surgery for gastroduodenal CD is lower than in ileal and/or colonic disease, and only a minority of the patients requires further surgical intervention. Bowel obstruction is a frequent indication for surgery in CD. Interventional or surgical therapy should be performed in chronic-recurrent obstruction, progressive stenosis and stenosis refractory to medical treatment. In short fibrous stenosis of the small bowel or ileocecal anastomosis without acute inflammation or perforating complications balloon dilatation or, if endoscopic access is not possible, strictureplasty should be performed. In all other cases, especially in colonic strictures with their increased risk of malignancy, resection is the treatment of choice. The results of balloon dilatation, strictureplasty or resection are comparable with five year reoperation rates reported between 20% and 38%.

Ascariasis of the alimentary tract, liver, pancreas and biliary system: its diagnosis by ultrasonography.

BACKGROUND/AIMS: The purpose of this study was to describe the echographic features of Ascaris lumbricoides invasion of the alimentary tract, biliary system, liver and pancreas. METHODOLOGY: We studied 38 patients with roundworm heavy infection whose diagnosis were primarily supported by ultrasonographic examination. RESULTS: Thirty-seven patients were admitted with the following clinical complications: bowel obstruction, intra and extrahepatic dilatation, acute cholecystitis, intrahepatic abscess, acute appendicitis, subphrenic collection and acute pancreatitis. Ultrasound scanning was able to recognize in 30 cases the echogenic, nonshadowing images of the worms as single or multiple strips; in 8 cases, coiled structures and amorphous material were detected. The "inner tube" sign was considered as the most specific one. In two cases the roundworms were displayed within the stomach, a curious finding, up to now never reported in medical literature. CONCLUSIONS: Real-time sonography represents an efficient, reliable and non-invasive diagnostic approach for hepatobiliary, enteric and pancreatic ascariasis.

Corrosive burns of the esophagus and stomach: a recommendation for an aggressive surgical approach.

During a six-year period ending in December, 1980, 62 patients with a history or clinical evidence of corrosive ingestion were admitted into our institutions. The majority were adults who had attempted suicide. Strong alkali (lye), the most common corrosive agent involved, was ingested by more than half of the patients (39). The remaining 23 patients had ingested weak alkali or nonalkali corrosive agents. Of the 27 patients with severe esophagogastric burns (second- and third-degree), a 43.5% incidence overall, liquid lye was responsible in 21, including 7 of 8 patients with extensive full-thickness esophagogastric necrosis. In sharp contrast, only 1 of the 23 patients who had ingested weak alkali or nonalkali corrosive agents had serious esophagogastric injury. In the first two years of this review, the management approach was the so-called standard one (esophagoscopy, steroids, antibiotics, and dilation) (Group 1). The results were disappointing. In 5 of 9 patients with endoscopic findings of second-degree burns, stricture requiring dilation developed, and all 4 with extensive full-thickness esophagogastric necrosis died. In contrast, during the last four years, with the adoption of a more aggressive surgical approach, that is, early surgical intervention including the use of an intraluminal esophageal stent and radical resection as indicated, missed or delayed diagnosis of full-thickness esophagogastric necrosis with its prohibitive mortality was avoided and the complication of severe esophageal stricture was virtually eliminated (Group 2).(ABSTRACT TRUNCATED AT 250 WORDS)
