Relationship between pancreatic resection volume and post-operative glucose intolerance in distal pancreatectomy: A retrospective study.

Background And Objectives: Some researchers are concerned that the performance of pancreatic resection in cases of low malignancy with distal localization will increase, resulting in the occurrence or worsening of post-operative glucose intolerance. Herein, we retrospectively investigated the relationship between the pancreatic resection ratio and post-operative glucose intolerance in distal pancreatectomy (DP).

Methods: Total 135 patients who underwent DP at our hospital and were followed up for > 12 months between January 2013 and December 2022 were included.

Ten-Year Follow-Up After Chemotherapy and Conversion Surgery for Human Epidermal Growth Factor Receptor 2-Positive Stage IV Esophagogastric Junction Cancer With a Pathological Complete Response: A Case Report.

Recent reports have focused on the usefulness of conversion surgery, in which chemotherapy is given to patients with unresectable advanced gastric cancer (GC), and radical surgery is subsequently performed if resection becomes possible; however, no consensus has been reached regarding the usefulness of this strategy. We report on a 74-year-old man who was diagnosed with esophagogastric junction cancer (T3N3M1 (LYM): stage IV). Chemotherapy was chosen and seven courses of S1 + cisplatin (SP) + trastuzumab (HCN) and two courses of S1 + HCN were administered.

However, previous studies on the treatment of POTS complicated by COVID-19 are lacking.

Presentation of unruptured right gastric aneurysm due to segmental arterial mediolysis resected laparoscopically: A case report.

Introduction: Timely diagnosis and treatment of intra-abdominal arterial aneurysms before rupture are highly recommended. We successfully prevented rupture through arterial aneurysm excision, highlighting the importance of the lack of reports on resection before rupture.

Case Presentation: A 60-year-old male with previous history of ureteral stones presented complaining primarily of left-sided abdominal pain.

Thoracoscopic esophagectomy with subcarinal lymph node dissection in the prone position for esophageal cancer with a right top pulmonary vein.

The right top pulmonary vein (RTPV), a rare pulmonary vein (PV) variant draining the right upper lobe, arises independently from the right superior PV, travels posterior to the right bronchial tree and drains directly into the left atrium (LA) or another PV. We report an RTPV discovered on preoperative computed tomography (CT) scanning in a 60-y-old man who subsequently underwent prone thoracoscopic esophagectomy and subcarinal lymph node dissection. The preoperative CT scan showed an anomalous vessel 7.

[A Case of Rhabdomyolysis Caused by Oxaliplatin during Postoperative Adjuvant Chemotherapy].

The patient was a 50-year-old male. At the age of 48 years, he had undergone total gastrectomy and right hemicolectomy simultaneously for gastric and ascending colon cancers. Since adjuvant chemotherapy has become common practice for patients with ascending colon cancer, capecitabine was administered for 6 months.

[A Case of Transverse Colon Cancer Complicated by Eosinophilic Granulomatosis with Polyangiitis].

A man in his 50s had undergone steroid therapy for eosinophilic granulomatosis with polyangiitis(EGPA). Since an examination for malignant tumors revealed type 0-Ⅰsp(cT1aN0M0)and type 2(cT2N0M0)lesions in the proximal and mid- transverse colon, respectively, he was referred to our department. Endoscopic resection was performed on the proximal lesion.

[A Case of Extramural Growth-Type Ileocecal Colon Cancer].

A woman in her 80s was diagnosed with an abdominal mass during physical examination. Contrast-enhanced computed tomography(CT)revealed a tumor with contrast enhancement outside the ileocecal region of the intestine, and the ileocolic artery penetrated the tumor. No tumor was detected by colonoscopy.

Long-term outcomes of endoscopic transpapillary gallbladder drainage using a novel spiral plastic stent in acute calculus cholecystitis.

Background: Endoscopic transpapillary gallbladder stenting (EGBS) is considered for patients with contraindications to early surgery for acute calculus cholecystitis. However, evidence regarding the long-term outcomes of EGBS is insufficient to date. The aim of the study was to evaluate the feasibility of EGBS as a bridge to or alternative to surgery when there are contraindications.
