Mixed neuroendocrine-non-neuroendocrine neoplasm of the colon treated with laparoscopic resection and adjuvant chemotherapy: a case report.

Mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) of the colon is rare with a poor prognosis. Since the first description of a mixed neoplasm 100 years ago, the nomenclature has evolved, most recently with the 2022 World Health Organization (WHO) classification system. We describe our experience of a case of locoregionally advanced MiNEN of the descending colon treated with curative laparoscopic resection and adjuvant chemotherapy.

Pathological complete response after chemotherapy in initially unresectable distal cholangiocarcinoma.

Surgical resection is the only curative treatment for cholangiocarcinoma, but it is often diagnosed at advanced stages, making surgical resection infeasible. Recently, the concept of conversion surgery has expanded the indications for surgical treatment, thanks to advancements in both perioperative management and chemotherapy. However, it remains unclear which patients benefit most from this treatment strategy.

Combined laparoscopic and thoracoscopic repair of adult right-sided Bochdalek hernia with massive liver prolapse: A case report.

Background: A Bochdalek hernia (BH) is a congenital diaphragmatic hernia that often develops in the neonatal period. BH typically occurs on the left side of the diaphragm. A right-sided BH in an adult is rare.

Retrospective observational cohort study of laparoscopic surgical strategies for gastrointestinal stromal tumors.

Laparoscopic surgery has been used to treat gastric submucosal tumors (SMTs). Laparoscopic and endoscopic cooperative surgery (LECS) has been used when subtotal resection has been difficult, which enabled resection of these tumors. In this study, we reviewed the medical records of patients with gastric SMTs who underwent laparoscopic surgery in our hospital with the aim of reporting the surgical indications, procedures (especially for LECS), and outcomes of surgery.

An Investigation of Factors Related to Food Intake Ability and Swallowing Difficulty After Surgery for Thoracic Esophageal Cancer.

Swallowing difficulty is among the major complications that can occur after surgery for thoracic esophageal cancer. Recurrent laryngeal nerve paralysis (RLNP) has been considered the most significant cause of a postoperative swallowing difficulty, but association between the two has not been adequately explained. We investigated the relation between postoperative RLNP and swallowing difficulty by means of video fluoroscopy.

[A Case in Which S-1 plus CDDP and S-1 Therapy Responded to Liver Metastasis Recurrence after Gastric Cancer Operation].

A 55-year-old man underwent distal gastrectomy and D2 lymph node dissection for type 2 gastric cancer of the antrum. One year later, CEA elevation was discovered, and contrast-enhanced abdominal computed tomography(CT)revealed a 40 mm mass in the liver(S8), which was judged to be a metastatic recurrence of the gastric cancer.S -1 plus CDDP was administered in 5 courses, followed by regular treatment with S-1 alone.

[Response to S-1+paclitaxel in far-advanced gastric cancer].

The patient was a 55-year-old man who was treated with S-1 and paclitaxel(PTX)combination chemotherapy for inoperable advanced gastric cancer in whom an abdominal CT examination had revealed peritoneal dissemination, pancreatic invasion, and ascites. A total of 15 courses of S-1 120 mg/day for 2 weeks followed by a 2-week rest period and PTX 90 mg/ body on day 1, 8, and 15 were administered. The CT examination after the completion of chemotherapy showed resolution of the ascites, and no evidence of peritoneal dissemination was observed on the images.
