RESUMO
BACKGROUND AND AIMS: The appropriate length of esophageal myotomy in peroral endoscopic myotomy (POEM) for achalasia cardia remains unclear. This study aimed to compare the outcome of short (≤3 cm) and long (≥6 cm) esophageal myotomy in patients with type I and II achalasia cardia. METHODS: This single-blinded, randomized controlled noninferiority trial was conducted at a tertiary center between July 2021 and December 2021. Patients with achalasia types I and II were randomized into short (≤3 cm) and long (≥6 cm) esophageal myotomy groups. The primary outcome of the study was clinical success (Eckardt score ≤3) 1 year after the procedure. The secondary outcomes included a comparison of technical success, operating duration, occurrence of intraoperative adverse events, alterations in integrated relaxation pressure (IRP), change in barium column height after 5 minutes (1 mo), and gastroesophageal reflux disease (3 mo) between the groups. RESULTS: Fifty-four patients were randomized into the short (n=27) or long (n=27) esophageal myotomy groups. Technical success rates were 100% (27/27) and 96.3% (26/27) in short myotomy (SM) and long myotomy (LM) groups, respectively. The clinical success rates were 96.3% (26/27) and 96.2% (25/26) in the SM and LM groups, respectively (P=0.998). The mean (±SD) length of the esophageal myotomy was 2.75±0.36 cm in the SM and 6.69±1.35 cm in the LM groups (P<0.001). The mean (±SD) procedure time for the SM and LM groups was 61.22±8.44 and 82.42±14.70 minutes (P<0.001), respectively. The mean integrated relaxation pressure (IRP), Eckardt score, adverse events, reflux esophagitis, symptomatic gastroesophageal reflux disease, and esophageal acid exposure (>6%) did not differ significantly between the 2 groups following POEM treatment. CONCLUSIONS: Short myotomy is noninferior to long myotomy in terms of clinical success, gastroesophageal reflux disease, and intraoperative adverse events at the short-term follow-up (P>0.05). Short myotomy resulted in a reduced operative time (P<0.05).
RESUMO
Extrahepatic portal vein thrombosis (EHPVO) is an uncommon cause of portal hypertension. In the long term, patients may develop portal cavernoma cholangiopathy (PCC). Up to 30%-40% of patients with EHPVO may not have shuntable veins and are often difficult to manage surgically. Interventional treatment including portal vein recanalisation-trans jugular intrahepatic portosystemic shunt (PVRecan-TIPS) has been used for patients with EHPVO. However, PV reconstruction-trans jugular intrahepatic portosystemic shunt (PVRecon-TIPS) and portal vein stenting are novel techniques for managing such patients with EHPVO with non-shuntable venous anatomy. In contrast to PVRecan-TIPS, PV reconstruction-TIPS (PVRecon-TIPS) is performed through intrahepatic collaterals. Here we present six cases of PCC who presented with recurrent acute variceal bleeding (AVB) and or refractory biliary stricture. They did not have any shuntable veins. PVRecon-TIPS was performed for five patients whilst PV stenting was done in one. Amongst the six patients, one died of sepsis whilst one who developed hyponatremia and hepatic encephalopathy was salvaged with conservative management. Following the procedure, they were started on anti-coagulation. Decompression of cavernoma was documented in all other patients. Biliary changes improved completely in 40% of patients.
RESUMO
Hemosuccus pancreaticus is characterized by intermittent bleeding from the ampulla of Vater due to the rupture of a pseudoaneurysm. There are significant diagnostic and therapeutic challenges associated with this rare and potentially life-threatening condition. We present a rare case in an 18-year-old man who presented with recurrent episodes of hematemesis and melena due to hemosuccus pancreaticus as a result of a left gastric artery pseudoaneurysm. Initial radiological angioembolization failed because of median arcuate ligament syndrome, and endoscopic ultrasound-guided glue embolization was successfully performed. This case further reinforces the importance of endoscopic ultrasound-guided therapy in the management of pseudoaneurysm after failed radiological treatment.
RESUMO
Hypogammaglobulinemia commonly presents with chronic diarrhea. Unfortunately, these patients require intravenous immunoglobulin (IVIG) transfusions of 400-800 mg/kg every 3-4 weeks as a standard treatment for hypogammaglobulinemia. Repeated transfusion of IVIG is costly, and many patients may not be able to afford it. We report the case of a young male with chronic small intestinal diarrhea who was later diagnosed with hypogammaglobulinemia. We treated the patient with fresh-frozen plasma (FFP) and the patient responded favorably. FFP transfusion may be an affordable alternative to IVIG in the treatment of hypogammaglobulinemia.
