Clinical management of stage III non-small cell lung cancer in India: An expert consensus statement.

Non-small cell lung cancer (NSCLC) is considered the most common type of lung cancer (>80% of all lung cancers); patients are often diagnosed at advanced stages of the disease. The management of NSCLC is considered challenging owing to variations in size, an extension of the tumors, involvement patterns, and classification. Although adequate literature and guidelines are available on the management of NSCLC in several countries, an Indian perspective on stage III NSCLC management is lacking. We used the modified Delphi approach to form consensus statements. A thorough literature search was done. The authors then convened and deliberated over published literature, available guidelines, and clinical judgment. Recommendation statements were formed for different clinical scenarios. These statements were sent as a form of survey to other oncologists, and their responses were recorded and mentioned. Evidence-based statements were formed for diagnosing and managing stage III NSCLC. These recommendation statements cover various aspects-surgical, radiation, and medical treatment in various clinical scenarios including adjuvant, neoadjuvant, and consolidation therapies.

Parosteal osteosarcoma with high-grade transformation and lung metastasis after 12 years: a rare presentation.

Parosteal osteosarcoma represents a low-grade, well-differentiated type of cortical surface osteosarcoma with a relatively better prognosis. Systemic metastasis is rare overall and occurs in 10-15% of patients only. Delayed recurrences (>5 years) of parosteal osteosarcoma are even rarer and only few isolated case reports of local recurrence with systemic metastasis occurring beyond 10 years exist in the literature. We present here a case of femoral parosteal osteosarcoma, successfully treated previously, that recurred with high-grade transformation locally and with lung metastasis after 12 years. The patient was managed by lung wedge resection followed by type A1 rotationplasty. Histopathology report confirmed evidence of high-grade transformation (de-differentiation) both locally and at the metastatic site, in view of strong CDK4 and MDM2 nuclear immuno-expression. The present report highlights the importance of long-term follow-up, even for a seemingly less aggressive osteosarcoma variant with identification of a novel pattern of lung metastasis.

Single-centre Indian case series using X or cross bar for Nuss procedure in pectus excavatum.

The modified Nuss procedure using two bars lying parallel or non-intersecting is use to correct pectus excavatum with varying degrees of patient satisfaction. This bar placement has its limitation for certain pectus excavatum morphology where the deformity is deep and focal or located below the subxiphoid. We have altered our bar placement so that bars intersects in an X or cross manner for such pectus morphology. We describe the X or cross bar placement and its specific indications based on morphology in a series of five patients from February 2019 until December 2019 with symmetrical focal deformity along the xiphisternum and asymmetric deformity below the xiphoid. The operating time varied from 90 to 120 min. There was no significant postoperative morbidity. They are on follow-up with period ranging from 4 to 15 months from the day of surgery. Early results show the X or cross bar Nuss procedure can be safely performed to achieve a desired long-term morphological correction of symmetric deep focal xiphisternal defects or asymmetric deformity below the xiphoid.

A giant mediastinal thymolipoma: a rare pathological entity.

Thymolipoma is a rarely seen benign pathological entity of anterior mediastinum and constitutes of around 2-7% of thymic tumors. They usually present as soft tissue mass composed of mature adipose tissue and thymic tissue, which are clinically silent most of the time, i.e., the reason they reach to a larger dimension before diagnosis. Preoperaative diagnosis is always challenging for the thymolipoma. We wish to report a case of the soft tissue mass of anterior mediastinum in a young male, which on surgical exploration and final histopathological examination was diagnosed as thymolipoma.

Anesthesia for minimally invasive chest wall reconstructive surgeries: Our experience and review of literature.

Minimal access procedures have revolutionized the field of surgery and opened newer challenges for the anesthesiologists. Pectus carinatum or pigeon chest is an uncommon chest wall deformity characterized by a protruding breast bone (sternum) and ribs caused by an overgrowth of the costal cartilages. It can cause a multitude of problems, including severe pain from an intercostal neuropathy, respiratory dysfunction, and psychologic issues from the cosmetic disfigurement. Pulmonary function indices, namely, forced expiratory volume over 1 s, forced vital capacity, vital capacity, and total lung capacity are markedly compromised in pectus excavatum. Earlier, open surgical correction in the form of the Ravitch procedure was followed. Currently, in the era of minimally invasive surgery, Nuss technique (pectus bar procedure) is a promising step in chest wall reconstructive surgery for pectus excavatum. Reverse Nuss is a corrective, minimally invasive surgery for pectus carinatum chest deformity. A tailor-made anesthetic technique for this new procedure has been described here based on the authors' personal experience and thorough review of literature based on Medline, Embase, and Scopus databases search.

Is There a Role for a Needle Thoracoscopic Pleural Biopsy under Local Anesthesia for Pleural Effusions?

BACKGROUND: A closed pleural biopsy is commonly performed for diagnosing patients exhibiting pleural effusion if prior thoracentesis is not diagnostic. However, the diagnostic yield of such biopsies is unsatisfactory. Instead, a thoracoscopic pleural biopsy is more useful and less painful. METHODS: We compared the diagnostic yield of needle thoracoscopic pleural biopsy performed under local anesthesia with that of closed pleural biopsy. Sixty-seven patients with pleural effusion were randomized into groups A and B. Group A patients were subjected to closed pleural biopsies, and group B patients were subjected to pleural biopsies performed using needle thoracoscopy under local anesthesia. RESULTS: The diagnostic yields and complication rates of the two groups were compared. The diagnostic yield was 55.6% in group A and 93.5% in group B (p<0.05). Procedure-related complications developed in seven group A patients but not in any group B patients. Of the seven complications, five were pneumothorax and two were vasovagal syncope. CONCLUSION: Needle thoracoscopic pleural biopsy under local anesthesia is a simple and safe procedure that has a high diagnostic yield. This procedure is recommended as a useful diagnostic modality if prior thoracentesis is non-diagnostic.

Pectus tunneloscopy: making Nuss procedure for pectus excavatum safe.

OBJECTIVES: The Nuss procedure for pectus excavatum involves the risk of cardiac injury during the creation of the retrosternal tunnel and during bar introduction or removal across the tunnel. A modified novel real-time technique for the safe introduction of the Nuss bar across the crucial retrosternal tunnel blind spot during introduction and removal is described. METHODS: In 2012, we devised a technique for real-time endovision-guided introduction of the Nuss bar called pectus tunneloscopy. Between February 2012 and December 2012, 6 patients with pectus excavatum had their bar introduced across the tunnel using this technique. RESULTS: This technique provided safe introduction and removal of the bar during the multiple times the bar is remodelled before final fixation. CONCLUSIONS: Pectus tunneloscopy is a real-time endovision surgical technique, providing safe introduction of the bar across the crucial retrosternal tunnel blind spot.

Cut throat zone II neck injury and advantage of a feeding jejunostomy.

Penetrating neck injuries account for 5-10% of trauma cases and are potentially life threatening. We report a case of cut- throat zone II neck injury in a 45-year-old male extending up to posterior pharyngeal wall and exposing the underlying cervical vertebra. Tracheostomy was done and wound repair was started from the posterior aspect in layers using 3-0 Vicryl. Intraoperatively, a conscious decision was taken for a feeding jejunostomy for postoperative feeding, which was likely to be prolonged, in view of sensory-nerve damage along the transected pharynx. Prolonged use of Nasogastric tube for postoperative feeding was thus avoided and the discomfort, risk of aspiration and foreign body at injury site eliminated. One week postoperative, the patient experienced severe bouts of coughing and restlessness on oral intake; during this period enteral nutrition was maintained through feeding jejunostomy. At the time of discharge at 1 month, the patient was accepting normal diet orally and was detubated and vocalizing normally. We conclude that postoperative nutrition is an important area to be considered for deep neck wound with nerve injuries due to delayed tolerance to oral feeding till the regeneration of sensory nerves. A feeding jejunostomy or feeding gastrostomy performed simultaneously in such patients with nerve injuries is far superior over nasogastric-tube feeding when prolonged postoperative feeding is expected.

Case report of a primary ovarian pregnancy in a primigravida.

Primary ovarian pregnancy occurs quite rarely and that too usually in young highly fertile multiparous women using intra uterine device. We present a case where a young primigravida presented with abdominal pain and was diagnosed as ectopic pregnancy and was confirmed intra-operatively and histopathologically as primary ovarian pregnancy, managed with partial ovariectomy.

Colonoscopic retrieval of migrated copper-T.

Intrauterine contraceptive devices have been in use for a long time as family planning measures, one of its complications of perforating the uterus and migrating into the peritoneal cavity is also well known. Retrieval in such cases depends on the location of the migrated intrauterine devices and involves laparotomy or laparoscopy. We present here such a case that migrated partially into the lumen of the rectosigmoid and was successfully removed using a colonoscope.

Video-assisted thoracic surgery for superior posterior mediastinal neurogenic tumour in the supine position.

Video-assisted thoracic surgery (VATS) for a superior posterior mediastinal lesion is routinely done in the lateral decubitus position similar to a standard thoracotomy using a double-lumen endotracheal tube for one-lung ventilation. This is an area above the level of the pericardium, with the superior thoracic opening as its superior limit and its inferior limit at the plane from the sternal angle to the level of intervertebral disc of thoracic 4 to 5 vertebra lying behind the great vessels. The lateral decubitus position has disadvantages of the double-lumen endotracheal tube getting malpositioned during repositioning from supine position to the lateral decubitus position, shoulder injuries due to the prolonged abnormal fixed posture and rarer injuries of the lower limb. There is no literature related to VATS in the supine position for treating lesions in the posterior mediastinum because the lung tissue falls in the dependent posterior mediastinum and obscures the field of surgery; however, VATS in the supine position is routinely done for lesions in the anterior mediastinum and single-stage bilateral spontaneous pneumothorax. Thus, in the selected cases, 'VATS in supine position' allows an invasive procedure to be completed in the most stable anatomical posture.
