Impact of Covid-19 pandemic on upper gastrointestinal cancer services: Experience from an oncosurgical unit.

Background The Covid-19 pandemic continues to affect the delivery of cancer care across the world. We evaluated the impact of the pandemic on the delivery of cancer care, to patients diagnosed with upper gastrointestinal (UGI) tract malignancies, during the first 4 months of the pandemic in India. Methods We retrospectively analysed a database of patients with UGI malignancies discussed in the Multidisciplinary Tumour Board (MDTB) between 24 March and 24 July 2020. The results in the study group were compared to that of a similar group of patients from the corresponding period in 2019. Results A total of 117 and 61 patients were discussed in the MDTB in 2019 and 2020, respectively, thereby showing a 48% reduction in the number of new cases seen in 2020. The reduction in the number of new cases was huge for oesophageal cancer (53-13; 75.5% reduction), compared to gastric cancer (53-43; 18.9%). The proportion of patients with metastatic disease at presentation was significantly higher in 2020, compared to 2019 (39.3% v. 23.1%; p=0.023). In 8 (13.1%) patients, the pre-existing treatment protocol had to be modified to suit the prevailing pandemic situation. Two patients with gastric cancer acquired asymptomatic Covid-19 infection during the treatment, which delayed the delivery of further therapy. Oncosurgeries were less in 2020 compared to 2019 (25 v. 63). The rate of 30-day major postoperative complications in 2020 was comparable with that in 2019 (12% v. 6.3%; p=0.4). Conclusions The number of new patients with UGI cancer, seeking elective cancer care and the number of oncosurgical procedures reduced during the Covid-19 pandemic. Continuous delivery of UGI cancer services was ensured during the pandemic through clinical prioritization, the adaptation of specific care pathways and selective modification of protocols, to suit the prevailing local conditions.

Postoperative outcomes in patients undergoing elective general surgery after recovery from Covid-19 at a tertiary care centre: A one-year case series.

Background Planned elective surgery had to be postponed for a large number of patients who tested positive for Covid-19 in the preoperative period. We aimed to assess the postoperative outcomes of patients who were operated on for elective indications, following recovery from Covid-19 infection. Methods We did a retrospective study of patients who underwent elective general surgery between 1 April 2020 and 31 March 2021, following recovery from Covid-19. The 30-day postoperative morbidity and mortality were analysed. The data relevant for the study were retrieved from the hospital's electronic medical records. Results Of the 109 patients included, 54.1% were women and the median (range) age was 49 (16-76) years; 53.2% of operations were performed for benign indications and the rest were for malignancies. Eighty-five (78%) patients underwent surgery following recovery from an asymptomatic Covid-19 infection and 23 (21.1%) patients following recovery from mild Covid-19 infection; 73.3% of the operations were performed following a planned delay of 2- 5 weeks from the diagnosis of Covid-19. The 30-day major postoperative morbidity (Clavien-Dindo grade ≥3) was 6.4%, the postoperative pulmonary morbidity was 0.9%, and there was no 30-day mortality. Conclusions Elective general surgical procedures can be done safely in patients who have recovered from asymptomatic and mild Covid-19 infection, following a minimum wait period of 2 weeks.

Feasibility, safety and oncological outcomes of minimally invasive oesophagectomy following neoadjuvant chemoradiotherapy for oesophageal squamous cell carcinoma - Experience from a tertiary care centre.

Background: Neoadjuvant chemoradiotherapy (nCRT) has improved the resectability and survival of operable oesophageal squamous cell carcinoma (OSCC). We aimed to study if nCRT for OSCC makes minimally invasive oesophagectomy (MIO) technically more challenging and if the peri-operative and oncological outcomes are acceptable for MIO following nCRT. Materials and Methods: A retrospective review of patients with OSCC (cT1-2N1-2, cT3-4aN0-2) treated with nCRT and MIO between 2013 and 2019 was performed. The operative details including the technical difficulty in tumour dissection and lymphadenectomy, the post-operative complications and oncological outcomes were studied. Results: Seventy-five patients (male:female - 50:25; mean [range] age - 55.49 ± 8.43 [22-72] years; stage II - 34.7%; stage III - 37.3%; stage IVA - 28.0%) were enrolled. The concurrent chemotherapy course was completed by 25.3% of patients and the most common reason limiting the completion of chemotherapy was neutropaenia (66.0%). A thoraco-laparoscopic (n = 60) or hybrid (n = 15) McKeown's oesophagectomy with a two-field lymphadenectomy was performed. The increased surgical difficulty was reported in 41 (54.7%) patients, particularly for mid-thoracic tumours and tumours exhibiting incomplete response. The 30-day overall and major complication rate was 48.0% and 20.0%, respectively, and there was no mortality. The rate of R0 resection, pathological complete response and median lymph nodal yield were 93.3%, 48% and 8 (range: 1-25), respectively. The mean overall survival (OS) was 62.2 months (95% confidence interval [CI]: 52.6-71.8) and recurrence-free survival (RFS) was 53.5 months (95% CI: 43.5-63.5). The 1-, 2- and 3-year OS and RFS were 89.5%, 78.8% and 64.4% and 71.1%, 61.3% and 56.6%, respectively. Conclusion: Minimally invasive McKeown's oesophagectomy is feasible and safe in patients with OSCC receiving nCRT. The radiation component of nCRT increases the degree of operative difficulty, especially in relation to the supracarinal dissection and lymphadenectomy. However, this drawback did not adversely affect the short-term surgical or the long-term oncological outcomes.

Minimally invasive surgery for adult oesophageal duplication cysts: Clinical profile and outcomes of treatment from a tertiary care centre and a review of literature.

BACKGROUND: Oesophageal duplication cysts (ODC) are rare in adults. Complete surgical excision is the ideal treatment. Conventionally, it is performed through a thoracotomy. We aimed to study the feasibility and safety of minimally invasive surgery (MIS) in the management of ODC and briefly reviewed the available literature. MATERIALS AND METHODS: A retrospective study of all adult patients with ODC diagnosed and treated at our tertiary care centre, from 2015 to 2019, was done. All patients were operated on by MIS. Their demographic, clinicopathological, radiological and surgical details and outcomes were analysed. RESULTS: A total of six patients (four females and two males) were diagnosed to have ODC by contrast-enhanced computed tomography. The mean age was 38 ± 4.4 years. The most common presenting complaint was chest pain (50%). Upper gastrointestinal endoscopy was normal in four patients. Endoscopic ultrasound was performed in five patients. In four patients, the cyst was located in the distal third of the oesophagus. The mean size of the cysts was 5.7 ± 2.02 cm. All the patients were operated upon by video-assisted thoracoscopic surgery (VATS). There was no conversion to open surgery. The resection was complete in all but one patient. The mean duration of surgery was 143.3 ± 35 min, and the average blood loss was 58.33 ± 20.4 mL. One patient had an oesophageal staple line leak on the 9th post-operative day. There was no mortality. The median duration of hospital stay was 7.5 days (range: 3-25 days). CONCLUSION: MIS is feasible and safe in the management of adult ODC.

Clinical profile and treatment outcomes of Boerhaave's syndrome: A 13-year experience from an upper gastrointestinal surgical unit.

Objectives: IBoerhaave's syndrome (BS) is a rare, but potentially fatal condition, characterized by barogenic esophageal rupture and carries a high mortality. We aimed to study our institutional experience of managing patients with BS. Material and Methods: A retrospective review of patients with BS presenting to a tertiary care centre from 2005 to 2018 was carried out in this study. Clinical presentation, diagnostic evaluations, treatments received, and treatment outcomes were studied. Perforations were classified as early (<24 hours) and delayed (>24 hours), based on the time elapsed. Surgical complications were graded using Clavien-Dindo grade. The Pittsburgh perforation severity score was correlated with short-term treatment outcomes. Results: Of the 12 patients [male, 75%; mean (range) age, 53 (28-80) years] included, 10 patients had a delayed (>24 hours) presentation. Chest pain was the dominant symptom (58.3%); six patients presented either in shock (n= 1) or with organ failure (n= 3) or both (n= 2). All the perforations were sited in the lower thoracic esophagus, of which three were contained and nine were uncontained. The seal of the perforation was achieved by surgical repair in four patients (primary repair, 2; repair over a T-tube, 2) and endoscopic techniques in four patients (clipping, 1; stenting, 3). Sepsis drainage [surgical, 7 (open-5, minimally-invasive-2); non-surgical, 5] and feeding jejunostomy were performed in all patients. Five (41.7%) patients received a re-intervention. Median (range) hospital stay was 25.5 (12-101) days, 30-day operative morbidity was 50%, and there was one in-hospital death. The Pittsburgh perforation severity score was as follows: 2-5 in two patients and >5 in 10 patients; there were more delayed presentations, increased surgical interventions, post-procedure morbidity, and in-hospital mortality in the latter group, but the differences were statistically not significant. In 11 patients followed-up [median (range):1507 (17-5929) days], there was no disease recurrence, symptomatic reflux or dysphagia. Conclusion: Favourable treatment outcomes, including reduced mortality and organ preservation can be achieved for Boerhaave's perforations, through a multimodality approach. Minimally invasive, endoluminal or open surgical techniques may be safely utilized in its management. The Pittsburgh severity score can be a useful clinical tool that can be used to select the initial intervention and to predict treatment outcomes.

Occult Omental Metastasis in Gastric Adenocarcinoma: An Analysis of Incidence, Predictors, and Outcomes.

Negine PaulIntroduction Traditionally, the concept of complete omentectomy during gastric resection for cancer was based on lymphatic drainage and the occurrence of occult omental metastasis (OM). However, recent emerging evidence has challenged this concept of complete omentectomy. We, therefore, aim to find the incidence and risk factors of occult OM and also evaluate the outcome of patients with and without such metastasis. Methods This is a single institutional, retrospective study of patients with gastric cancer who underwent curative radical gastrectomy for a period of 3 years (April 1, 2016, to March 31, 2019). A complete omentectomy was performed in all patients and the omentum and nodal stations were dissected in the resected specimen and sent for pathological analysis. Clinical and epidemiological data were collected from the hospital patient database and analysis was done. Results A total of 185 patients have been included in the study, with a mean age of 53.84 years. Twenty of the 185 patients had OM (10.8%). Age, sex, location of the tumor, and neoadjuvant chemotherapy were not statistically significant in predicting OM. However, tumor size and tumor depth were found to have a significant association with OM. The occurrence of OM was more likely to be associated with disease recurrence, especially in the peritoneum. The mean overall survival was 38.15 months (±3.33 SD), whereas patients with OM had lower survival, 23.31 months (±7.79 SD), with a p -value of 0.012. Conclusion OM was not encountered in T1 and T2 gastric cancers and the incidence of OM in T3 and T4 tumors was approximately 12.7%. Therefore, complete omentectomy may be omitted in early T1/T2 tumors. OM was associated with poor prognosis, increased peritoneal recurrence, and decreased overall survival, in spite of a complete omentectomy, and may serve as a prognostic indicator for disease recurrence and overall survival.

'Wandering spleen with acute torsion' : a rare indication for splenectomy in an adult, complicated by postoperative splanchnic venous thrombosis and intestinal gangrene.

Wandering spleen (WS) is a hypermobile spleen that, due to the laxity of its ligaments, is prone to torsion. We report a case of a 45-year-old multiparous woman who presented with acute abdominal pain and a tender palpable mass. A contrast-enhanced computed tomography scan of the abdomen showed a WS with torsion. She underwent an emergency splenectomy and was discharged after an uneventful recovery. She was readmitted with splanchnic venous thrombosis and was managed with therapeutic low-molecular-weight heparin (LMWH) and discharged. Twenty days later, she presented with new-onset abdominal pain. She had not complied with LMWH as advised. The thrombosis had progressed, leading to small bowel gangrene, requiring resection and a stoma. Due to frequent metabolic disturbances, an early reversal of stoma was performed. She was lost to follow-up thereafter. This case highlights a rare indication for emergency splenectomy and one of its major postoperative complications.

Exocrine Pancreatic Insufficiency Following Gastric Resectional Surgery-is Routine Pancreatic Enzyme Replacement Therapy Necessary?

The data on exocrine pancreatic insufficiency (EPI) following gastric resectional surgery is variable, ranging from 26% to as high as 100%. This study aimed to document symptomatic EPI following gastric resectional surgery and to objectively document EPI, by fecal elastase (FE) testing. This was a cross-sectional study among patients undergoing gastric resection for adenocarcinoma of the stomach, at the Upper Gastrointestinal Surgical Unit at the Christian Medical College Hospital, Vellore, India. A detailed questionnaire was administered to the patients in the postoperative period, to evaluate clinical symptoms of EPI. Further, study participants were tested for FE pre- and postoperatively. Of the 60 patients in this study, the postoperative questionnaire administered to all patients during follow up. None showed symptoms suggestive of EPI. Pre- and post-operative FE testing were feasible in 27 of the 60 patients, which showed a 33% incidence of EPI. None of the patients had clinical symptoms of EPI, following gastric resectional surgery, on short-term follow-up. However, more than a third of the patients tested developed asymptomatic EPI after gastric resectional surgery, based on FE testing. This may be explained by the fact that in the early postoperative period, EPI following gastric resectional surgery perhaps has a mild, subclinical presentation. Therefore routine pancreatic supplementation after gastric resectional surgery may not be necessary. However, one needs to carefully look for worsening of symptoms of EPI on long-term follow-up, which may necessitate appropriate investigations followed by pancreatic enzyme replacement therapy.

Patterns of Recurrence in Locally Advanced Resectable Oesophageal Carcinoma: Retrospective Review from a Tertiary Cancer Centre in South India.

PURPOSE: The study aims to analyse patterns of recurrence following neoadjuvant treatment and surgery in carcinoma oesophagus with an intent to postulate optimal nodal radiation. METHODOLOGY: A retrospective review of patients who presented to our centre within a 5-year period (2014-2018), with recurrence following sequential neoadjuvant treatment and radical surgery, was conducted in this single-institution study. The patterns of recurrence and duration of disease-free survival were analysed. RESULTS: Twenty-one patients (14 men, 7 women) presented with recurrence, of which 13, 7, and 1 patient(s) had received NACT, NACTRT, or both, respectively. Six patients who did not receive neoadjuvant radiotherapy received adjuvant RT. Among the 10 patients who had nodal recurrence after RT (either neoadjuvant or adjuvant), 6 and 4 patients had in-field and out-of-field nodal recurrences, respectively-the latter were equally distributed within 5 cm and outside 5 cm of the PTV margin. CONCLUSION: Among the patients who presented with recurrence, more than half had not received neoadjuvant RT (treated in the 'pre-CROSS era' or due to long-segment disease), reasserting the therapeutic superiority of NACTRT. Increased regularity of recurrences in the draining nodal region was not noted in this study, but large-scale, prospective, randomised head-to-head comparative trials to determine optimal nodal irradiation in carcinoma oesophagus are required.

Profile and outcome of patients with ground-level falls.

BACKGROUND: A ground-level fall is one of the most common modes of injury sustained across all age groups. For older adults, ground level falls can result in multiple injuries and are associated with significant morbidity and mortality. METHODOLOGY: This retrospective observational study included all patients presenting with fall from a ground level to our emergency department (ED) from January 2018 to December 2018. Demographics, details of incident, severity of injury, and outcome were analyzed. RESULTS: During the study period, 596 patients with a mean age of 40.9 (standard deviation [SD]: 25.9) years were included in the analysis. A quarter (23%) were aged less than 15 years, while the elderly (>60 years) comprised of 29.5%. Half the patients were triaged as priority 2 (53.8%). The lower limbs (36.6%), upper limbs (23.9%), and face (15.3%) were the body areas that were most commonly injured. The new injury severity score (NISS) was more than 8 in 28% of patients. Multivariate logistic regression analysis showed the elderly (>60 years) to have a higher odds (2.51 95% confidence interval [CI]: 1.57-4.02) of sustaining a fracture of a dislocation. One fifth of the patients (120/596; 20.1%) required hospital admission with only one fatality. Fifteen patients (2.5%) left the hospital against medical advice. Two-thirds (66.3%) required only conservative management, while 19.9% required major surgical intervention. CONCLUSION: A ground-level fall is a common mode of injury in children (<15 years) and the elderly (>60 years). The extremities and face are the most common areas of the body that are prone to injuries. Age-friendly infrastructure modifications at home, work places, and in public areas for elders and ensuring playground safety for children are the needs of the hour to decrease falls on level ground.

Surgical Outcomes Associated with Operable Gastric Cancer in a Tertiary Care Indian Hospital.

PURPOSE: Data on operable gastric cancer from India is sparse. The purpose of this study was to investigate the clinical details, histopathological demographics, and 5-year overall survival (OS) and disease free survival (DFS) associated with operable, non-metastatic gastric cancer in a dedicated upper gastrointestinal (GI) surgical unit in India. MATERIALS AND METHODS: Data for patients diagnosed with operable gastric cancer between January 2006 and December 2014 were retrospectively analyzed. Data were collected from electronic hospital records in addition to mail and telephonic interviews when possible. RESULTS: A total of 427 patients were included. The tumor was located in the pyloro-antral region in 263 patients (61.7%). Subtotal gastrectomy was performed in 291 patients and total gastrectomy in 136 patients. Tumor stage classification revealed 43 patients (10.0%) with stage I, 40 patients (9.4%) with stage IIA, 59 patients (13.9%) with stage IIB, 76 patients (17.8%) with stage IIIA, 96 patients (22.5%) with stage IIIB, and 113 patients (26.4%) with stage IIIC disease. Follow-up data were available for 71.6% of the patients with a mean duration of 32.4 months. Five-year DFS and OS were 39% and 59%, respectively. CONCLUSIONS: Despite presenting at an advanced stage, the 5-year DFS and OS of patients with operable gastric cancer treated at a dedicated upper GI unit of a tertiary care center in India was good.

Gastrointestinal Stromal Tumours: Review of 150 Cases from a Single Centre.

Gastrointestinal stromal tumours (GIST) are the most common mesenchymal tumours of the gastrointestinal tract. They constitute a significant percentage ranging from 1-2 % of all the gastrointestinal neoplasms [11]. Knowledge on the molecular biology and behavior of these tumours is still not very clear. The clinicopathologial features are variable and surgical resection with chemotherapy is the main modality of treatment. We have retrospectively analyzed the clinicopathological features, treatment and prognosis of 150 patients managed in the Department of Surgery. Retrospective review of the records of 150 patients diagnosed with gastrointestinal stromal tumours and managed during the period January 2006 to December 2011. Clinicopathological features, immunohistochemistry, mitotic index, surgical resection adjuvant chemotherapy and survival analyzed. One hundred and fifty patients diagnosed with GIST and treated were reviewed. Ninety five of them were males (63.3 %). The tumour was most commonly seen during the fourth and fifth decades of life. Abdominal pain (52 %), intestinal bleeding (40 %) and abdominal mass (25 %) were the common clinical symptoms. Sixty percent of the tumours (90/150) were located in the stomach followed by small bowel (20 %) and duodenum (14.6 %). One hundred and thirty-five patients underwent excision of the tumour and five patients had multi organ resection of the adjacent organs like spleen, tail of the pancreas and kidney. Fifteen patients (10 %) received neoadjuvant Imatinib for down staging of the tumour prior to surgery. The tumour size ranged from 1 to 34 cm. One third of the tumours (42/150) belonged to the high-grade category. KIT protein (CD117) was positive in 90 %( 135/150), while CD34 was positive in 50 % (74/150) of tumours. Majority of the patients with high and intermediate-risk category received adjuvant Imatinib (65/77). Seventeen patients (11.3 %) developed recurrence of the tumour on follow-up and rest of the patients had stable disease. Eight of the 15 patients (53 %) who had advanced disease developed recurrence of the disease over 6 months to 1 year. Fifteen patients died on follow-up between 2 and 5 years. Gastrointestinal tumours are the most common non epithelial tumour of the GIT. GISTS are found to show a male preponderance and are common during the fourth and fifth decades. Abdominal pain and intestinal bleeding are the most common clinical presentation. Most of the tumours were located in the stomach. Surgical resection is the best modality of treatment for operable lesions. Tyrosine kinase receptor (KIT) inhibitor like imatinib is used for adjuvant treatment. Regular follow-up with ultra sonogram or computed tomogram helps in diagnosing disease recurrence.

Spontaneous liver rupture: A report of two cases.

Spontaneous bleeding due to a non traumatic liver rupture is a rare occurrence. However, it is associated with high morbidity and mortality. Usually the predisposing factors are like Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome in pregnant women and other liver diseases. It is generally diagnosed by imaging studies such as ultra sonogram or computerized tomogram (CT). Due to its rarity no standard treatment has been described. Here, we report two cases of spontaneous rupture of normal liver in two young males. They presented with severe shock and hemoperitoneum. The diagnosis was confirmed by CT. They were managed surgically. In case of hemoperitoneum, spontaneous liver rupture should be considered. An early aggressive resuscitation and appropriate intervention gives better outcome.

Eosinophilic disorders of the gastrointestinal tract: imaging features.

Eosinophilic disorders of the gastrointestinal tract are increasingly rare but remain an important cause of long-standing gastrointestinal symptoms. Diagnosis is usually delayed because the disease mimics other inflammatory disorders and is often not suspected initially. We report a series of four cases to highlight the various imaging appearances of this condition. Two patients presented with upper gastrointestinal involvement, one patient presented with small and large bowel involvement, and one patient presented with diffuse involvement of the entire gastrointestinal tract.
