Primary anorectal malignant melanoma with laparoscopic abdominoperineal resection: a case study and review of the relevant literature.

ARMM is a disease with a poor prognosis. ARMM is often diagnosed at an advanced stage, and the 5-year survival rate of ARMM is < 20%. Although the number of case reports on ARMM is gradually increasing, the optimal treatment strategy for ARMM remains controversial.

Portal vein thrombosis in liver cirrhosis.

Portal vein thrombosis (PVT) is considered to be a frequent complication of liver cirrhosis. However, unlike PVT in patients without cirrhosis, very few data are available on the natural history and management of PVT in cirrhosis, despite its association with potentially life-threatening conditions, such as gastroesophageal bleeding and acute intestinal ischemia. Moreover, no consensus regarding PVT in cirrhosis exists.

Treatment of bleeding rectal varices with transumbilical venous obliteration of the inferior mesenteric vein.

A 56-year-old male with alcohol-induced liver cirrhosis developed rectal varices. He had a prior history of treatment for esophageal varices with endoscopic variceal ligation. Despite the repeated treatment for rectal varices with endoscopic variceal ligation, endoscopic injection sclerotherapy, and surgery, the bleeding from the rectal varices could not be controlled.

Rigid and flexible endoscopic rendezvous in spatium peritonealis may be an effective tactic for laparoscopic megasplenectomy: significant implications for pure natural orifice translumenal endoscopic surgery.

Background: We recently experienced 10 patients with cirrhosis who underwent laparoscopic splenectomy. A portion of these patients underwent dissection with a flexible endoscope in the peritoneal cavity. This pilot study mainly focused on the technical aspects and immediate results.

Impact of balloon-occluded retrograde transvenous obliteration on management of isolated fundal gastric variceal bleeding.

Aim:   Although endoscopic injection of cyanoacrylate (CA) is the only effective method for treating isolated fundal gastric variceal bleeding, the rebleeding rate is relatively high. This study investigated the efficacy of balloon-occluded retrograde transvenous obliteration (B-RTO) for management of isolated fundal gastric variceal bleeding.

Methods:   Patients (n = 110) with acute or recent bleeding from isolated fundal gastric varices (GV) were retrospectively studied.
