Jayson M Moloney, Philip S L Gan
BACKGROUND AND OBJECTIVES: Hybrid-natural orifice surgery combines the advantages of traditional transabdominal laparoscopic surgery, while limiting surgical trauma to the abdominal wall. Among various routes of intra-abdominal access, the transvaginal method is most appealing because of its utility and proven safety. We describe a series of 4 colonic resections performed with this approach, combined with minilaparoscopy and needlescopic approaches, and discuss the technical aspects, efficacy, and applicability of this technique...

Cancer of uterine cervix is one of the most common malignancies in women. Metastatic recurrence of cervical cancer in spleen is rare, mostly seen in autopsies. Splenic metastasis from cervical cancer in a living patient without disseminated metastases is rarer. Here, we present the case of a lady aged 46 years with cervical cancer-squamous cell carcinoma-who had undergone radical hysterectomy and postoperative 50 Gy of intensity modulated radiation therapy in 25 fractions and 50 mg of weekly cisplatin for 6 weeks...

PURPOSE: To investigate hepatosplenic volumetry at MDCT for non-invasive prediction of hepatic fibrosis. METHODS: Hepatosplenic volume analysis in 624 patients (mean age, 48.8 years; 311 M/313 F) at MDCT was performed using dedicated software and compared against pathological fibrosis stage (F0 = 374; F1 = 48; F2 = 40; F3 = 65; F4 = 97). The liver segmental volume ratio (LSVR) was defined by Couinaud segments I-III over segments IV-VIII. All pre-cirrhotic fibrosis stages (METAVIR F1-F3) were based on liver biopsy within 1 year of MDCT...

Colonic complications are rare after acute pancreatitis but are associated with a high mortality. Possible complications include mechanical obstruction, ischaemic necrosis, haemorrhage, and fistula. We report a case of large bowel obstruction in a 31-year-old postpartum female, secondary to severe gallstone pancreatitis. The patient required emergency laparotomy and segmental bowel resection, as well as cholecystectomy. Presentation of obstruction occurs during the acute episode or can be delayed for several weeks...

Introduction Splenectomy in children is nowadays widely performed by laparoscopy, the major risk being operative hemorrhage. We hereby compare the results of two different techniques of vascular control. Materials and Methods We retrospectively reviewed all patients undergoing a laparoscopic splenectomy (LS) for hematologic disease at a single institution from 2004 to 2013. LS was performed by a lateral approach. The 10-mm optic port was placed in the umbilicus and two 5-mm working ports were placed in the left lower quadrant and in the right upper quadrant near the midline...

OBJECTIVES: Evidence suggests a possible role of Fusobacterium nucleatum in colorectal carcinogenesis, especially in right-sided proximal colorectum. Considering a change in bowel contents and microbiome from proximal to distal colorectal segments, we hypothesized that the proportion of colorectal carcinoma enriched with F. nucleatum might gradually increase along the bowel subsites from rectum to cecum. METHODS: A retrospective, cross-sectional analysis was conducted on 1,102 colon and rectal carcinomas in molecular pathological epidemiology databases of the Nurses' Health Study and the Health Professionals Follow-up Study...

Hirschsprung disease (HSCR) is a congenital disorder characterized by intestinal aganglionosis leading to pseudoobstruction. The majority of cases are limited to the rectum or rectosigmoid (S-HSCR). A variably longer segment can be affected (L-HSCR), which may show many deviations from S-HSCR. We retrospectively reviewed 48 clinicopathologically confirmed total cases of HSCR at a single institution in a 21-year period to identify L-HSCR cases and determine their deviations from known features of S-HSCR. Eight L-HSCR cases were found where aganglionosis extended to the terminal ileum (7/8) or to the splenic flexure (1/8)...

Segmental arterial mediolysis (SAM) is a rare, nonarteriosclerotic, noninflammatory vascular disease and mostly affects medium-to-large sized abdominal arteries as well as presents with hemorrhages in the abdominal cavity. We report the case of a patient with SAM of the celiac, right renal, jejunal branch of the superior mesenteric, left gastric, and splenic arteries who was diagnosed by excluding other causes and in whom transcatheter embolization was performed in two different sessions, but he died because of an undefined reason...

BACKGROUND: Perforation of the colon occurring during or shortly following colonoscopy or barium enema is a rare complication of collagenous colitis (CC). "Spontaneous" perforation in CC, in which no instigating factor is identified, is even less common, with only five cases reported to date. We report herein an additional case of spontaneous perforation in previously undiagnosed CC and review the clinical and pathological features of previously reported cases. CASE PRESENTATION: An 80 year old woman presented to the emergency department with abdominal pain preceded by approximately one month of frequent non-bloody diarrhea...

Porcine models of extended hepatectomy and liver transplantation (LT) of reduced graft have been widely used for studying the small-for-size (SFS) syndrome and the various modalities of portal inflow modulation (PIM). However, considerable heterogeneity exists among the studies and their results. The aim of this review was to assess the main advantages and drawbacks of the different porcine models of SFS LT and SFS hepatectomy, and propose a standardized anatomical nomenclature for the various models. The MEDLINE database was searched for articles reporting porcine models of reduced graft LT or hepatectomy of more than 65%...

This is a case report that suggests the possible association between multiple splanchnic arterial aneurysms and long-distance running. The clinical features of one patient admitted at Chungbuk National University Hospital for treatment of multiple splanchnic arterial aneurysms were reviewed. A 54-year-old man had a recurrent, intermittent and epigastric pain for 2 months. There was no abnormality in gastroscopy and colonoscopy. An abdominal computed tomography angiography documented calcified superior mesenteric artery (SMA) and splenic artery aneurysms...

It is unclear if persistent splenomegaly in the presence of a negative positron emission tomography (PET) scan before allogeneic hematopoietic cell transplantation (HCT) influences post-transplantation outcomes in patients with lymphoma. We retrospectively reviewed records of 152 patients who underwent allogeneic HCT for various lymphomas. Centralized review of pretransplantation computed tomography (CT) and PET images was performed. Spleen volume (SV) was measured using the freehand volume segmentation tool in AW Workstation software (General Electric, Waukesha, WI)...

Hydatid disease is an endemic disease especially in underdeveloped and developing countries affecting mostly the liver and lungs. The hydatid cysts located in other sites are mostly due to rupture of primary liver or splenic cysts. We present a primary small intestine hydatid cyst resected laparoscopically with the affected intestinal segment. As far as we know, this is the first report of a primary small intestine hydatid disease in the literature.

INTRODUCTION: Several factors are used to stratify the probability of polyp recurrence. However, there are no studies correlating the location of the initial polyps and the recurrent ones. The aim of this study was to verify whether the polyp location at the surveillance colonoscopy was correlated with the location of the previously excised polyps at the baseline colonoscopy. METHODS: A retrospective study of patients submitted to colonoscopy with presence and excision of all polyps, followed by a surveillance colonoscopy...

REVIEW

As basic knowledge for evaluation of pancreatic toxicity, anatomical structures were compared among experimental animal species, including rats, dogs, monkeys, and minipigs. In terms of gross anatomy, the pancreases of dogs, monkeys, and minipigs are compact and similar to that of humans. The rat pancreas is relatively compact at the splenic segment, but the duodenal segment is dispersed within the mesentery. In terms of histology, the islet of each animal is characterized by a topographic distribution pattern of α- versus β-cells...

Pancreatic cancer is known for vague symptoms that lead to a delay in diagnosis, and hence most cases are found at an advanced stage. Many complications can happen secondary to pancreatic cancer including diabetes, malabsorption, and deep venous thrombosis. Sinistral (segmental or left-sided) portal hypertension (SPH) refers to portal hypertension confined to the left-sided segment of the portal venous system namely the splenic side, and the most common etiology is splenic vein thrombosis (SVT). We present here a case of a 66-year-old male with advanced pancreatic cancer who died due to bleeding secondary to SVT...
