Oesophageal adenocarcinoma following gastric band surgery in two patients

Abstract

Oesophageal adenocarcinoma following gastric band surgery has only been reported three times previously. The incidence is higher in morbidly obese patients, and its pathogenesis is correlated to reflux-induced microenvironmental changes. Bariatric surgery is transformative and its potential benefit for a substantial population is huge. Although no causal relationship with bariatric procedures has been evidenced to date, symptoms of adenocarcinoma—particularly anorexia, weight loss and dysphagia—can easily be overshadowed by alterations in eating patterns associated with weight-loss procedures. We report two cases of oesophageal adenocarcinoma in patients who had undergone a gastric banding procedure, and invite readers to consider the role that pre- and post-operative acid reflux dynamics may have precipitating neoplastic disease, and how endoscopic surveillance may play a role in prevention.

Gastric outlet obstruction secondary to orbera intragastric balloon

Abstract

Intragastric balloons are used as a temporary restrictive method in obesity to induce weight loss. They are typically recommended when patients have mild obesity and have failed traditional first line treatments of diet, exercise and behaviour modification. We report a case of a 45-year-old female who presented with nausea, vomiting and abdominal pain two weeks following an uncomplicated insertion of an intragastric balloon. Following investigation, she was found to have a gastric outlet obstruction which required endoscopic removal of the balloon. While a rare occurrence, gastric outlet obstruction as seen in this case, highlights the importance of early recognition in order to proceed with swift diagnosis and intervention in order to prevent significant morbidity such as ischaemia and perforation.

Surgical management of a giant right atrial myxoma

Abstract

Cardiac tumours represent around 0.2% of tumours overall, and primary cardiac tumours are even more uncommon. We report the case of a 72-year-old female with a 7 cm × 4 cm right atrial mass which was prolapsing through the tricuspid valve. The mass was resected and histological analysis confirmed a myxoma. This report describes a rare finding of a giant right atrial mxyoma and subsequent surgical management.

Tulip piercing the aorta: a rare case of IVC filter aortic perforation and obstruction

ABSTRACT

Prolonged implantation of inferior vena cava (IVC) filters can lead to significant morbidity. We present a 25-year-old man with antiphospholipid syndrome, lower extremity deep vein thrombosis, and subsequent Gunther-Tulip IVC filter placement. More than 10 years following IVC filter placement he developed progressive abdominal and back pains. Cross-sectional angiography revealed that he had a chronic IVC occlusion, and IVC filter limb extensions into the infrarenal aorta, lumbar spine, and right psoas muscle. The IVC filter limb protruding into the aorta had also pierced through the backwall to lead to partial lumen thrombosis and obstruction. The patient underwent a transabdominal exposure of the infrarenal IVC and aorta, filter explantation and aortic patch angioplasty repair. This case highlights the severity of aortic injury from a protruding IVC filter limb that necessitated open aortic repair. Improved selection, monitoring and retrieval stewardship of IVC filters can help reduce the risk of unintended aortic complications.

Hemothorax after emphysematous bullectomy using a linear staple device with bioabsorbable polyglycolic acid felt

Abstract

A linear stapler with bioabsorbable polyglycolic acid felt is widely used during the resection of emphysematous lung. Currently, an improved staple device with polyglycolic acid felt is being used owing to a history of complications, such as bleeding, that was associated with the previous model. Here, we report a case of a 69-year-old man who presented to our department for treatment of left lower lobe lung cancer using the new staple device. A left lower lobectomy and emphysematous bullectomy were performed. Reoperation was performed following the diagnosis of a postoperative hemothorax. During that operation, a staple with reinforcing material was found to be in contact with the proliferating vessels on the lung surface, resulting in an active bleed. The vessel was cauterized, and the bleeding stopped. This is the first case study to report bleeding associated with the improved staple device.

A left ventricular assist device for a patient with peripartum cardiomyopathy

Abstract

Since its introduction in Japan in 1980, the extracorporeal left ventricular assist device has been used as a bridge to the recovery of cardiac function or to heart transplantation by many institutions. In this case report, we describe a 23-year-old female with peripartum cardiomyopathy. She had a persistently low cardiac index despite intensive care with intravenous inotropes, intra-aortic balloon pumping and extracorporeal membrane oxygenation; thus, we implanted an extracorporeal left ventricular assist device. Thereafter, her cardiac function gradually improved; the device was removed 2 months after the implantation. She currently has good heart function.

Endo GIA stapler malfunction in a small bowel loop resection

Abstract

Endovascular gastrointestinal anastomosis (Endo-GIA) staplers are widely used in various surgical procedures despite difficulties in operating them and associated mechanical failures. We present a case of a patient whose post-operative recovery was complicated by intraoperative Endo-GIA stapler failure, which is rarely reported in literature. Our report describes the behavior and consequences of surgical stapler failure so surgeons can anticipate challenges of newer surgical devices while maintaining optimal patient outcomes.

Primitive synovial sarcoma of suboccipital region in child

Abstract

Synovial sarcoma (SS) most commonly affects the lower limbs of males in the third to fifth decades of life, with masses of the head and neck accounting for 3–10% of all cases, mainly as a metastatic lesion. The lack of specific symptoms and radiological features in addition to the diversity of their microscopic aspects may cause confusion in the diagnosis; hence, knowledge of the unusual locations of SSs is very important. The immunohistochemistry, and more recently the cytogenetic studies, contribute to the differential diagnosis. We report the case of a 12-year-old girl with a rare primary SS in the suboccipital region, which underwent complete surgical resection.

Segmental intestinal dilatation associated with ileal gastric heterotopia in a young woman

Abstract

Segmental intestinal dilatation (SID) is a rare gastrointestinal disorder characterized by marked bowel dilatation and can result in signs of intestinal obstruction, abdominal pain and gastrointestinal bleeding. SID is seen most commonly in pediatric patients, with most cases being reported in neonates and infants. Definitive treatment is resection of the dilated segment of bowel with primary anastomosis. This article describes a rare case of SID in an adult patient—a 26-year-old female who presented with chronic abdominal pain. The patient experienced complete resolution of symptoms following surgical resection.

High-dose intraoperative remifentanil infusion increases early postoperative analgesic consumption: a prospective, randomized, double-blind controlled study

Abstract

Purpose

The purpose of this study was to determine whether intraoperative infusion of remifentanil induces acute tolerance to opioids, and compare the postoperative pain and opioid consumption by the effect site concentrations of remifentanil.

Methods

One hundred and ninety-eight patients undergoing gastrectomy were randomly assigned to maintain target effect site concentrations of remifentanil at 0 (Group 1, n = 39), 2 (Group 2, n = 40), 4 (Group 3, n = 39), 8 (Group 4, n = 40), or 12 ng/ml (Group 5, n = 40) during operation. Postoperative pain intensities and fentanyl requirement were recorded at postoperative 2, 6, 24, and 48 h.

Results

Fentanyl requirement for postoperative 2 h was significantly greater in Group 5 compared to Group 1 (376 ± 116 vs. 283 ± 129 µg, P = 0.03). However, there were no differences in fentanyl requirements among the groups after postoperative 2 h. Also, total fentanyl consumption for 48 h was similar in all groups (Group 1; 3106 ± 629, Group 2; 2970 ± 705, Group 3; 3017 ± 555, Group 4; 3151 ± 606, and Group 5; 2984 ± 443 µg, P = 0.717). Pain scores at rest and during deep breathing were comparable in all groups at the time of each examination.

Conclusion

Intraoperative infusion of remifentanil with 12 ng/ml of effect site concentration in patients undergoing gastrectomy increases early postoperative fentanyl requirement. Acute opioid tolerance would be developed by higher concentration of remifentanil than dosage of common anesthetic practice.

Hip Mobilization at Preterm Age May Accelerate Developmental Dysplasia Recovery

Purpose. Few studies have described mobilization approaches in developmental dysplasia of the hip (DDH). The present study describes the hip mobilization of a preterm infant (born at 33 6/7 weeks of gestational age) diagnosed with DDH. Design and Methods. During the 43-day hospital stay, the infant was seen twice a week (ten sessions, 20 minutes each). All sessions included hip approximation maneuvers, with the hip positioned in abduction, lateral rotation and flexion, and lower limbs passive mobilization, which were taught to the mother. Early intervention with auditory, tactile, visual, and vestibular stimulations was also performed. The infant was assessed with hip ultrasound before and after treatment. Results. At 34 2/7 weeks of gestational age, she was classified as Graf IIa (left: alpha: 55°, beta: 68°; right: alpha: 59°, beta: 64°). At 40 5/7 weeks, she was classified as Graf I for left (alpha: 67°; beta: 42°) and right (alpha: 66°; beta: 42°) hips. Practical Implications. The intervention seemed to accelerate the acquisition of stability of dysplasic hips in a preterm infant. The outcome supports further investigation of hip approximation maneuvers as part of early stimulation in preterm infants with DDH during hospital stay.

Dexmedetomidine preserves the endothelial glycocalyx and improves survival in a rat heatstroke model

Abstract

Purpose

Heatstroke causes systemic inflammation, followed by vascular endothelial damage. The normal vascular endothelium is coated by endothelial glycocalyx (EGCX). Dexmedetomidine (DEX) has an anti-inflammatory effect, but there has been little investigation on the influence of heatstroke on EGCX and the effect of DEX on this condition. Therefore, we examined whether EGCX was disrupted in heatstroke and if DEX improved survival and preserves EGCX.

Methods

Anesthetized Wistar rats were randomly assigned to three groups: a DEX group treated with DEX (5 µg/kg/h) and 0.9% saline infused continuously at 10 ml/kg/h during heat exposure; a NSS group given 0.9% saline during heat exposure; and a SHAM group given 0.9% saline alone without heat exposure. Heatstroke was induced by exposure to an ambient temperature of 40 °C with relative humidity of 60%. The survival rate was assessed up to 2 h after the start of heat exposure. Plasma levels of syndecan-1 and the thickness of EGCX using electron microscopy were measured when the systolic blood pressure fell to less than 80 mmHg.

Results

The survival rate after 2 h of heat exposure was significantly higher in the DEX group compared to the NSS group (89% vs. 22%, P = 0.004). Plasma levels of syndecan-1 were 0.6 ± 1.3, 9.7 ± 5.9, and 2.1 ± 3.4 ng/ml in the SHAM, NSS and DEX groups, respectively (P = 0.013). The thickness of EGCX was significantly higher in the DEX group compared with the NSS group (P = 0.001).

Conclusions

EGCX was disrupted in heatstroke, and DEX improved survival and preserved EGCX.
