Transthoracic versus transhiatal esophagectomy for esophageal carcinoma: experience from a single tertiary care institution.

BACKGROUND: There is a lot of controversy about the best surgical treatment for esophageal carcinoma. METHODS: In this retrospective study, 382 patients with carcinoma of the mid-to-distal esophagus underwent transthoracic or transhiatal esophagectomy. Early morbidity and mortality were compared. Principal endpoints were disease-free survival (DFS) and overall survival (OS). RESULTS: A total of 177 patients underwent transthoracic esophagectomy, and 205 patients underwent transhiatal esophagectomy. Demographic characteristics and characteristics of the tumor were similar in the two groups. Perioperative and postoperative morbidity was higher after transhiatal esophagectomy. In-hospital mortality was also higher after transhiatal esophagectomy. The median follow-up was 4.3 years. Estimated 3-year DFS rates were 44.63 and 31.21%, whereas the 3-year OS rates were 57.06 and 41.46% for the transthoracic and transhiatal groups, respectively (statistically significant). Also, the estimated 5-year DFS rates were 26.55 and 21.46%, whereas the 5-year OS rates were 32.76 and 30.24% for the transthoracic and transhiatal groups, respectively (statistically not significant). CONCLUSIONS: Transhiatal esophagectomy was associated with higher perioperative and postoperative morbidity and in-hospital mortality than transthoracic esophagectomy. The DFS and OS were higher in the transthoracic group and were statistically significant at 3 years but statistically insignificant at 5 years.

Ascaris through a chest tube: a rare presentation.

A rare case of an Ascaris worm emerging through an intercostal chest tube is reported here because of its unusual presentation. A five-year-old male child had a liver abscess, which had ruptured into the right pleural cavity. An intercostal chest tube was inserted for right pleural effusion. On the 5th postoperative day, a 7 cm long worm was noticed emerging through the chest tube. Ascaris lumbricoides infestation can lead to serious complications because of the mobility of the worms. Though complications such as intestinal obstruction, volvulus, gangrene, pancreatitis, biliary obstruction, cholangiohepatitis, and liver abscess have been reported to occur, intrapleural ascariasis is an extremely rare situation. This report describes a clinical situation of intrapleural ascariasis and emphasizes the importance of remaining aware of this rare complication of ascariasis.

Missile vascular injuries: 19-year experience.

BACKGROUND: Missile vascular injuries have reached an epidemic proportion in Kashmir valley since the eruption of militancy. The present study was undertaken to analyze the mode, pattern, presentation, and management of missile vascular injuries. METHODS: A retrospective study of patients with missile vascular injury from January 1990 to October 2008 was undertaken. Five hundred eighty patients with missile vascular injury were studied. All patients with vascular injury due to causes other than missiles were excluded from the study. RESULTS: Most of the patients were treated by interpositional saphenous vein graft or end-to-end anastomosis. The most common complication was wound infection (22.7%) followed by graft occlusion (3.8%). The amputation rate was 3.3% and was higher in patients with a delay of >6 hours to revascularization and associated fractures. CONCLUSION: Missile vascular injury requires prompt resuscitation and revascularization. Preoperative angiography is seldom necessary. Doppler study may sometimes be needed to aid in the diagnosis.

Outcome of the surgical treatment of bullous lung disease: a prospective study.

BACKGROUND: This study aimed at evaluating the outcome of surgery for bullous lung disease by comparing the preoperative and postoperative subjective dyspnea score, pulmonary function and clinical features. MATERIALS AND METHODS: This prospective study was conducted from May 2009 to October 2011, on 54 patients operated for bullous lung disease. Follow-up at 3-6 months consisted of taking a comprehensive history, physical examination, radiological work-up, and evaluation of changes in subjective dyspnea score, arterial blood gas analysis (ABG), and pulmonary function test (PFT). After comparison with preoperative values, the student's paired t-test was used to calculate the statistical significance. RESULTS: With approximately 21.6 cases per year, the most common underlying lung pathology was primary bullous lung disease, followed by COPD. The most common presenting complaint was spontaneous pneumothorax in tall young adults in their fourth decade of life with a history of smoking. Bullectomy, with or without decortication, was done for all cases. Improvement in mean PaO2 (arterial partial pressure of oxygen), SaO2 (arterial oxygen saturation) and PaCO2 (arterial partial pressure of carbon dioxide) was seen in most cases but was statistically insignificant. Improvement in mean FEV1 (forced expiratory volume in 1st second), FVC (forced vital capacity) and FEV1 / FVC was statistically significant, with FEV1 being the most reliable indicator of postoperative progress. Improvement in subjective dyspnea score was statistically significant and showed an inverse correlation with FEV1. Those with diffuse pulmonary parenchymal involvement had poorer baseline values and less significant postoperative improvement. Complications occurred more commonly in those with diffuse disease. Mortality was seen exclusively in those with diffuse disease. CONCLUSION: We conclude that surgery is required for bullous lung disease more frequently in our community since we have a high number of young patients with primary bullous lung disease and localized parenchymal involvement and these patients have a good surgical outcome. Potentially fatal complications like pneumothorax and recurrent infections can therefore be prevented in them. Those with underlying diffuse disease and severely decreased FEV1 (especially below 1 L) also benefit from surgery but require careful patient selection.

Unusual metastasis to all the digits of both hands in a patient previously operated on for esophageal carcinoma.

Metastatic malignancies to the hand, although rare, usually develop from lung, breast, and kidney tumors. Very rarely the origin is the gastrointestinal system. Metastases to the bones of the hand can cause pain, swelling, soft tissue ulceration, and osteolytic destruction. We present a patient with metastatic tumors to all digits of both hands 2.5 years after being operated on for esophageal carcinoma. The patient underwent amputation of the left little finger followed by systemic chemotherapy. The histopathological diagnosis was consistent with that of the primary tumor. This case is being presented for being the rarest of its kind and may even be the first of its nature in the world's literature as an extensive search has not shown another of its kind to date.

Hydatid embolism from a thoracic aortic pseudoaneurysm presenting as gangrenous toes.

Cystic echinococcosis (hydatid cyst), caused by Echinococcus granulosus, has worldwide distribution and poses a health problem in endemic areas. Embolization of hydatid cysts into the vascular tree is an unusual manifestation of the disease. The hydatid embolism results from spontaneous or traumatic rupture of the cyst, and rare case reports of this kind are not well documented in the literature. We report a case of a hydatid embolism from a ruptured hydatid in a pseudoaneurysm of the thoracic aorta. A 45-year-old woman presented with gangrenous changes of the toes of her right foot. After embolectomy, the histopathology of the embolus was doubtful about its being blood clots around hydatid membranes. Postoperatively, computed tomography (CT) of the chest revealed a pseudoaneurysm of the descending thoracic aorta. Definitive surgery for the pseudoaneurysm was done during a second operation. Numerous hydatid cysts were evacuated from the pseudoaneurysm. This report emphasizes the need for an early diagnosis and treatment of echinococcosis before disabling and life-threatening complications occur.

Traumatic diaphragmatic rupture, a diagnostic dilemma in the presence of eventration: a case report.

Eventration of the diaphragm is the condition where the muscle is permanently elevated, but retains its continuity and attachments to the costal margins. Traumatic diaphragmatic rupture is a recognized consequence of high velocity blunt trauma to the abdomen usually a result of motor vehicle accident. Multi-slice CT and Magnetic Resonance Imaging in the pre-operative evaluation of trauma patients, diaphragmatic rupture can be still overlooked if not evaluated with the fair degree of clinical suspicion, more so if it is associated with an eventration of diaphragm - as was in our case.
