We report a case with extrahepatic portal venous obstruction (EHPVO), who presented with recurrent bleeding following a previous devascularization procedure and needed an emergency distal spleno-renal shunt (DSRS). Due to technical difficulty because of previous scarring, the adrenal vein was used as a conduit between the splenic vein and renal vein. The shunt's patent and the patient has been bleed-free for 2 years.
We have reviewed the history of laparoscopic fusions and our results over the past two years, utilizing a femoral ring allograft and bone graft in 51 patients. The rate of fusion in this series is nearly 100%, with relief of radicular pain in about 90%. The average hospital stay is approximately two days and return to work is about six weeks. Minimally invasive techniques for spinal surgery will evolve with time and will become the standard of care in the near future.
A patient with hepatocellular carcinoma with neuroendocrine features is reported. Identification of this tumor is essential due to its aggressive behavior and the differences in the treatment and clinical control of the patient.
We report a patient with hepatocellular carcinoma (HCC) with membranous obstruction of the inferior vena cava (IVC). He underwent balloon dilatation of the IVC with good results. The HCC was managed by chemoembolization followed by resection. At follow up of eleven months the patient is asymptomatic.
A patient with a peripancreatic lymph node tuberculosis mimicking pancreatic pseudocyst is reported, which was diagnosed on exploration to be a tuberculous cold abscess. The patient responded to antituberculous drugs after drainage of the cold abscess.
We report a 48-year-old woman with foregut ischemia with splenic infarct due to isolated celiac artery obstruction. The patient presented with acute-onset pain in the epigastrium 10-15 min after every meal. Investigations revealed obstruction of the celiac artery by artheromatous plaque. This patient had an acute thrombosis, which responded to anticoagulation.
BACKGROUND: Leaking abdominal wounds (LAW) are associated with high patient morbidity. OBJECTIVES: To evaluate the efficacy of a self-adhesive drape (Opsite) with suction drains for the management of LAW. METHODS: Twenty patients with LAW (14 intestinal fistula, 4 biliary fistula, 2 ascites leak) were subjected to the use of a self-adhesive drape with a Romovac suction drain. Conventional wound management was used for the first 5 days, followed by the application of Opsite drape. The parameters evaluated were quantity of the effluent, skin integrity, ease of application, patient comfort and cost effectiveness. A discomfort score (based on four parameters: mobility, skin excoriation, wetness and unpleasant odor) was recorded on day 1 (pre conventional), day 5 (post conventional-pre Opsite), and day 5 after Opsite application. Opsite drape was changed whenever required. RESULTS: The discomfort score was not altered with conventional therapy but was lower following Opsite application: mobility (0 vs 2), skin excoriation (0 vs 2), wetness (0.5 vs 2) and odor (0 vs 1). Opsite drape allowed accurate measurement of the effluent in all patients. The drape required change after a median of 14 days (range 10 to 18). CONCLUSIONS: Opsite drape is easy to apply on LAW, is effective in containing the effluent, and is associated with low patient morbidity.
We report a 49-year-old lady who presented with acute Budd-Chiari syndrome. Spiral CT scan showed inferior vein cava (IVC) tumor and ischemia of the right liver secondary to hepatic vein blockage. These were confirmed by MRI scan and IVC gram, at which time tissue diagnosis was obtained. At surgery, the tumor was seen to originate from the infrahepatic IVC and extended to the level of the diaphragm, blocking the hepatic vein outflow. The tumor was excised completely. Histology confirmed it to be leiomyosarcoma of the IVC. The patient is well, without recurrence of symptoms or tumor, 10 months later.
OBJECTIVES: To assess the morbidity, mortality and 1- and 2-year survival rates, and safety of pancreaticoduodenectomy for periampullary (including pancreatic head) carcinomas in a non-oncology surgical set-up. METHODS: Records of 45 patients undergoing pancreaticoduodenectomies for periampullary cancers between July 1996 and April 2000 were reviewed. These included ampullary (n=23), pancreatic (14) and duodenal (2) adenocarcinomas, lower-end cholangiocarcinoma (5), and ampullary carcinoid (1). Thirty-seven patients underwent the Whipple procedure and 8 underwent the pylorus-preserving modification. RESULTS: The overall mortality rate was 11% and morbidity rate was 46%. Wound infection was the most common postoperative complication. The 1- and 2-year survival rates for periampullary cancers were 61% and 39% and those for pancreatic cancers were 57% and 36%, respectively. CONCLUSION: Pancreaticoduodenectomy for periampullary tumors remains a formidable procedure in our set-up. However, it can be performed safely with low mortality and morbidity rates.
BACKGROUND/AIMS: To assess the incidence of extensive portal and splenic vein thrombosis in patients with extrahepatic portal vein obstruction and determine the differences in presentation, portal hemodynamics and management as compared to patients with portal vein thrombosis alone. METHODOLOGY: 118 patients of extrahepatic portal vein obstruction presenting with variceal hemorrhage, having received no definitive treatment prior to presentation were divided into two groups--with portal and splenic vein thrombosis and with portal vein thrombosis, based on ultrasonography and splenoportography. Collateralization patterns on splenoportography were studied. Results of endoscopic variceal sclerotherapy were compared. RESULTS: Portal and splenic vein thrombosis was seen in 39 patients. Collateralization in case of portal and splenic vein thrombosis, in contrast to portal vein thrombosis, was predominantly left sided (74% vs. 9%, p < 0.0001). Fundal gastric varices were seen more often in patients with portal and splenic vein thrombosis (28% vs. 11%, p = 0.02), developing even after variceal obliteration, though obliteration was achieved in fewer sessions. Surgery for control of variceal bleed was performed more in the portal and splenic vein thrombosis group (33% vs. 15%, p = 0.02), especially for gastric varices (28% vs. 9%, p = 0.006). CONCLUSIONS: Portal and splenic vein thrombosis is present in 33% of patients with extrahepatic portal vein obstruction. Hemodynamic patterns differ, accounting for the preponderance of gastric varices on presentation in patients with portal and splenic vein thrombosis and an increased need for surgery.
A blocked distal splenorenal shunt presents with torrential bleeding from gastric varices. Reoperation in the presence of portal hypertension in an unstable patient is difficult. Two patients with a blocked distal splenorenal shunt were subjected to splenic artery embolization. This stopped variceal bleeding from gastric varices resulting from the congested spleen due to thrombosis of the splenic vein. The procedure was successful in stopping the acute bleed in both patients. There were no serious complications or recurrent variceal bleeding and the varices were collapsed at one year on follow-up endoscopy. Splenic artery embolization is a safe and effective minimally invasive treatment for patients with bleeding from a blocked distal splenorenal shunt.

A case of follicular variant of papillary thyroid carcinoma presenting with a right maxillary mass is described. This is perhaps the first instance of maxillary metastasis from papillary thyroid carcinoma.
Polypropylene mesh, the routinely used material for mesh laparostomies is expensive. A economical and easily available substitute-nylon net was compared with polypropylene mesh with regard to efficacy and wound complications in a retrospective study. 51 patients, 25 in the polypropylene mesh group and 26 in the nylon net group were studied. The groups were matched with respect to age, sex, indication for surgery and mortality. The mean hospital stay (65 vs 54 days), fate of the wound, incidence of mesh extrusion (26% vs 20%), bowel perforation (1 vs none) and incisional hernia formation (21% vs 20%) in those with polypropylene mesh and nylon net respectively was similar. In conclusion, nylon net is an effective and inexpensive indigenous substitute for polypropylene mesh for mesh laparostomies.
