RESUMEN
Oesophageal mucocele is an uncommon complication of bipolar exclusion of oesophagus. Traditionally, this condition is managed through thoracotomy which is associated with significant morbidity. The present report outlines the thoracoscopic management of oesophageal mucocele following surgical exclusion for oesophageal perforation. Left thoracoscopic oesophagectomy for oesophageal mucocele described in this report has not been published earlier.
RESUMEN
Background The pre-malignant tendency of the normal, non-affected portion of the pancreas is not as well explored as the multicentricity documented in pancreatic cancer cases. In order to ascertain the expression of inflammatory markers and Erythroblastic Oncogene B (ErbB2) in the non-affected pancreas in patients with pancreatic cancer, a case-control study was carried out. Materials and methods In patients who underwent pancreatoduodenectomy for pancreatic cancer (PC), pro-inflammatory genes and a tumor marker, erythroblastic oncogene 2 (ErbB2) in the epidermal growth factor receptor family were analyzed in the pancreatic tissue at the cut surface of the normal pancreas using qRT-PCR. Twenty patients diagnosed with Chronic pancreatitis (CP) after Frey's surgical procedure were selected, and their pancreatic tissues were analyzed as controls. The HPLC-purified primers were designed using National Center for Biotechnology Information (NCBI) software. The primer's specificity was verified for gene expression analysis using the Basic Local Alignment Search Tool (BLAST). The genes under study were normalized using ß-actin as the housekeeping gene, and the 2-ddct method was used to compute the fold change compared to the control sample. Results Patients with margin-positive were not included. Pro-inflammatory genes (TNF-α, NF-kß, and COX-2) had significantly lower foldchange in PC patients compared to the CP group. The CP control group had higher levels of IL-6 gene expression than the PC group. Patients with pancreatic cancer had a considerably higher expression of the ErbB2 gene than patients with CP. Conclusion The upregulated ErbB2 gene in the unaffected pancreatic tissue of pancreatic cancer patients, when compared to controls, indicates that the remaining pancreas may have the capacity to cause cancer. Proto-oncogene may play a role in the pathophysiologic process in patients with pancreatic cancer.
RESUMEN
Visceral venous aneurysms are exceedingly rare clinical entities reported in the literature. Venous aneurysms are usually acquired in origin, with most often portal hypertension as the underlying pathology. Most venous aneurysms are incidental findings on imaging. Complications of venous aneurysms like rupture with catastrophic outcomes had been reported. However, no clear guidelines exist regarding the management of portal venous aneurysms as most of the data is available only from case reports. Here, we report a rare finding of fusiform superior mesenteric vein (SMV) aneurysm with arteriovenous communication and portal vein thrombosis in the background of non-cirrhotic portal hypertension.
RESUMEN
Improved insights into the pathophysiology of acute pancreatitis have paved the way for identification of distinct entities in the spectrum of the disease. The presence of necrotising inflammation limited to peripancreatic tissue with a normal appearance of pancreas is one such entity. This entity, described as extrapancreatic necrotising pancreatitis (EPN), is considered a less aggressive form of acute necrotising pancreatitis. This entity needs to be recognized precisely and managed accordingly among patients with acute pancreatitis. However, EPN has not been highlighted in the revised classification of acute pancreatitis. Here we report two patients with EPN with varied presentations and diverse management and outcome.
RESUMEN
Variations in the hepatic artery's anatomy can significantly impact planning and executing pancreatic and hepatobiliary surgeries. Of these, the commonest are variations of right and left hepatic arteries originating from superior mesenteric and left gastric arteries, respectively. The anomalous origin of the right hepatic artery from the gastroduodenal artery (GDA) is among the rarest and most challenging anatomy, especially in patients undergoing pancreatoduodenectomy (PD) since GDA ligation is a mandatory step, which may threaten the liver blood supply. We present a 62-year-old male with suspected distal cholangiocarcinoma and plan a robot-assisted pancreatoduodenectomy. Preoperative computed tomography evaluation revealed an anomalous segment 6 artery arising from the GDA and coursing posterolaterally to the common bile duct in the hepatoduodenal ligament. Also, the patient had a replacement left hepatic artery originating from the left gastric artery. The described vascular anomaly has not been previously reported in patients undergoing PD. Awareness of vascular anomalies is the key to performing oncologically radical surgery without increasing bleeding and ischemic complications in patients undergoing complex procedures like PD.
RESUMEN
Introduction The utilization of robot-assisted technique for splenectomy has recently gained popularity especially in patients undergoing splenectomy for hematological indications owing to its magnification of and easy manipulation of internal abdominal organs. Moreover, robotic splenectomy emerged as an essential teaching module before approaching more complex robotic procedures. Methods A total of 43 elective splenectomies were performed for hematological indications in Department of Surgical Gastroenterology, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER) between January 2018 to July 2023 of which 14 patients underwent robotic splenectomy. All patients underwent lateral approach of robotic splenectomy with a modification of avoiding the lesser sac dissection. Prospectively maintained data were retrospectively analyzed and results were recorded in terms of intra-operative time taken, blood loss, need for blood and blood product transfusion and postoperative morbidity and mortality. Results The indications for patients who underwent robotic splenectomy include idiopathic thrombocytopenic purpura in eight patients, autoimmune hemolytic anemia in three patients, Evans syndrome in one patient and hereditary spherocytosis in two patients. The median splenic diameter was 14.8cm and the median platelet count before the operation was 10,800 cells/cubic millimeter (7000-3,20,000). The mean operative time was 92 minutes and blood loss was 40ml. The median duration of hospital stay was 2.4 days. All 14 patients had therapeutic success and there was no procedure-related mortality or morbidity. Conclusion Robotic splenectomy using the modified lateral approach can safely be performed with comparable operative time, blood loss and overall morbidity. However further studies are mandatory to confirm the advantage of this modified technique of lateral approach of robotic splenectomy.
RESUMEN
In India, cervical cancer is the second leading cause of cancer-related mortality among females. Around one-third are expected to develop recurrence or metastasis during follow-up. Liver metastasis is rarely requiring palliative treatment. Patient compliance to strict follow-up is vital to detect early metastasis to be able to improve survival. A 58-year-old lady (International Federation of Gynecology and Obstetrics [FIGO] stage IIIB) was treated with concurrent chemoradiotherapy. During follow-up, she had complained of abdominal pain for which cross-sectional imaging revealed a left lobe liver lesion fistulizing into the stomach. Liver metastasis fistulizing into the stomach is a rarity, and a biopsy is required to confirm metastasis or maybe a second primary. Although palliation in the form of chemotherapy is the standard, minor or major hepatectomy can be considered in patients with good performance status at high-volume centers. A tailored multidisciplinary team approach is required for better survival.
RESUMEN
Compared to less invasive measures, surgical repair is the most effective modality for managing benign acquired tracheoesophageal fistula (TEF). Traditionally, this involves dismantling of the fistula and suture repair of tracheal and esophageal defects using a lateral or direct approach. However, the best approach remains a subject of debate. We describe a novel and simple technique for dismantling a benign acquired TEF with the use of an endo-stapler and interposition with sternocleidomastoid (SCM) muscle flap. Eleven TEF patients underwent repair using this stapled repair technique. Retrospectively, the perioperative and long-term outcomes were assessed in these patients. There were no cases of procedure-related mortality or airway-related complications. Two patients developed transient vocal cord palsy and one developed esophageal leak. At a mean follow-up of 21.4 months, no fistula recurrence, dysphagia, or tracheal stenosis was observed. Hence stapled dismantling and SCM muscle interposition is a simple and safe technique for repair of benign acquired TEF.
RESUMEN
Gastrointestinal stromal tumors (GISTs) are the most common nonepithelial solid neoplasms involving the alimentary tract. We report a case of cystic GIST with multiple cystic metastases. A 61-year-old man presented with upper abdominal pain for two months. Further evaluation revealed a large intra-abdominal cyst in the lesser sac and another cyst over the segment VII of the liver on imaging. Multiple intra-abdominal hydatidoses were suspected based on the imaging and its endemic nature in the geographical area. However, the hydatid serology was normal. In view of hemorrhagic cyst fluid, an intraoperative frozen biopsy of the cyst wall was done, which revealed features suspicious of a mesenchymal tumor. Sleeve gastrectomy with en-bloc excision of the gastric cyst, excision of the hepatic cyst, and complete excision of multiple other intra-abdominal cysts were performed considering GIST as a possibility. Histology revealed a clear cell variant of GIST. Gastric GISTs primarily presenting as multiple intra-abdominal cysts and of clear cell histological variants had never been reported in the literature. The patient was started on imatinib, and he has shown no evidence of recurrence after 12 months of follow-up. A high index of suspicion, intraoperative frozen section, meticulous surgery, and immunohistochemistry are all crucial for the effective management of atypical cases. GIST may be considered as a part of differential diagnosis in clinical scenarios with multiple intra-abdominal cysts, especially in the equivocal setting.
RESUMEN
BACKGROUND: Modified Makuuchi (MM) incision is less popular among the urological fraternity as Chevron, subcostal, flank, and midline incisions are commonly used for most of the complex renal and adrenal conditions. We present our experience and report the outcomes of patients operated using this incision. MATERIALS AND METHODS: The records of patients who underwent open surgery for upper abdominal urological conditions using MM incision over the last five years in our department were retrospectively reviewed. Patient demographics, laterality of the lesion, size of the lesion, level of inferior vena caval (IVC) thrombus, intraoperative blood loss, local tumor invasion, need for concomitant hepatectomy, need of diaphragmatic resection, use of self-retaining retractors, operative time, hospital stay, wound-related complications, and readmissions were analyzed. RESULTS: Some 18 patients underwent open surgery by this incision for various complex renal and adrenal conditions during the study period. Patients included those with large upper pole renal and adrenal masses, renovascular conditions like renal artery aneurysm, renal/adrenal masses with liver and diaphragmatic infiltration requiring hepatectomy, diaphragmatic resections, or IVC thrombectomy. The mean size of renal and adrenal masses was 13.8 (±6.3) cm, mean operative time was 370 (±210.6) minutes, mean blood loss was 1124 (±990.3) mL, and mean hospital stay was 11.65 (±13.2) days. Four patients had surgical site infection (SSI) and one had readmission. CONCLUSION: The MM incision can be widely adapted for complex renal and adrenal surgeries and should become a part of the various commonly used incisions by urologists.
RESUMEN
Left renal vein (LRV) has been considered as the most suitable vein for proximal splenorenal shunt (PSRS), a commonly performed shunt for non-cirrhotic portal hypertension. Anatomical anomalies in LRV that can pose technical difficulty during shunt procedure are reported in 10% cases. We report a rare anomaly of LRV which precluded performance of standard end-to-side proximal splenorenal shunt and describe its management by performing an interposition end-to-end proximal splenorenal shunt. A 50-year-old female presented with recurrent episodes of upper gastrointestinal bleed for five years. She was pale and had a massive splenomegaly. There were no signs of encephalopathy. Upper gastrointestinal (UGI) endoscopy revealed three columns of grade 3 esophageal varices, large fundal varices and mild portal hypertensive gastropathy. Duplex ultrasound and contrast-enhanced computed tomography (CECT) of the abdomen was suggestive of non-cirrhotic portal fibrosis. She underwent an interposition end-to-end proximal splenorenal shunt with inferior branch of left renal vein. She developed partial shunt thrombosis at follow-up of 18 months and underwent balloon angioplasty and metallic stenting of shunt. She is doing well at 24 months follow-up with no recurrence of symptoms and a patent shunt. In conclusion, the presence of renal vein abnormalities does not preclude performance of PSRS with suitable modifications. A high index of suspicion is required to detect them preoperatively to avoid technical difficulties and to plan modifications of PSRS. Interposition end-to-end graft proximal splenorenal shunt is a valid option with good primary-assisted patency rate and clinical outcome.
RESUMEN
Removal of a transesophageal migrated foreign body is recommended to prevent injury to adjacent structures. As the endoscopic approach is not feasible for a transesophageal foreign body migrated into the mediastinum, the thoracoscopic approach is recommended. The thoracoscopic approach often requires single lung ventilation and is associated with more pulmonary complications. The use of a laparoscopic approach to remove a mediastinal foreign body has not been reported earlier. In this report, the authors describe a laparoscopic approach for the removal of a transesophageal migrated foreign body into the lower mediastinum.
