Segmental gastrectomy with radical lymph node dissection for early gastric cancer

AIM: To describe a new surgical technique and evaluate the early results of segmental gastrectomy (SG) with modified D2 lymph node (LN) dissection for early gastric cancer (EGC). METHODS: Fourteen patients with EGC underwent SG with modified D2 dissection from 2006 to 2008. Their operative results and postoperative courses were compared with those of 17 patients who had distal gastrectomy (DG) for EGC during the same period. RESULTS: Operating time, blood loss, and hospital stay were similar between the 2 groups. Postoperative complications developed significantly more frequently in the DG group than in the SG group. Mean number of dissected LNs per each station in the SG group was comparable with that in the DG group. Postoperative recovery of body weight was significantly better in the SG group than in the DG group. The incidence of reflux esophagitis and gastritis after surgery was less frequent in the SG group than in the DG group.CONCLUSION: SG with modified D2 LN dissection may be a new function-preserving gastrectomy that is feasible for treatment of EGC with possible LN involvement.

Preoperative detection and localization of small bowel hemangioma: Two case reports

Among the various diagnostic modalities for small bowel hemangioma, video capsule endoscopy (VCE) and double-balloon enteroscopy (DBE) can be recommended as part of the work-up in patients with obscure gastrointestinal bleeding (OGIB). DBE is superior to VCE in the accuracy of diagnosis and therapeutic potential, while in most cases total enteroscopy cannot be achieved through only the antegrade or retrograde DBE procedures. As treatment for small bowel bleeding, especially spout bleeding, localization of the lesion for the decision of DBE insertion facilitates early treatment, such as endoscopic hemostatic clipping, allowing patients to avoid useless transfusion and the worsening of their disease into life-threatening status. Applying endoscopic India ink marking prior to laparoscopic surgical resection is a particularly useful technique for more minimally invasive treatment. We report two cases of small bowel hemangioma found in examinations for OGIB that were treated with combination of laparoscopic and endoscopic modalities.

Review of the literature laparoscopic surgery for metastatic hepatic leiomyosarcoma associated with smooth muscle tumor of uncertain malignant potential: Case report

Metastatic hepatic leiomyosarcoma is a rare malignant smooth muscle tumor.We report a case of metastatic hepatic leiomyosarcoma associated with smooth muscle tumor of uncertain malignant potential(STUMP).A 68-year-old female presented with a liver mass(60 mm × 40 mm, Segment 4).She underwent left salpingooophorectomy for an ovary tumor with STUMP in a broad ligament 6 years ago.Though FDG-PET showed obvious metabolically active foci, abnormal metabolically active foci other than the lesion were not detected.A malignant liver tumor was strongly suspected and laparoscopic partial liver resection was performed with vessel-sealing devices using the crush clamping method and Pringle maneuver.Immunohistochemical findings revealed metastatic liver leiomyosarcoma associated with STUMP in a broad ligament.This case is an extremely rare case of malignant transformation from primary STUMP to metastatic hepatic leiomyosarcoma.It provides important evidence regarding the treatment for metastatic hepatic leiomyosarcoma associated with STUMP.
