Review
Recent refinements in cross-sectional imaging have dramatically modified the investigation of the jejunum. Improvements in multidetector row computed tomography (MDCT) and magnetic resonance (MR) imaging technology have made detection and characterization of jejunal abnormalities easier. Current options include MDCT and MR imaging using either enterography or enteroclysis. The goal of this pictorial review is to outline the current imaging techniques that are used to investigate the jejunum and illustrate the most common conditions that affect this small bowel segment with a specific focus on MDCT and MR imaging using enterography or enteroclysis. MR imaging used in conjunction with optimal jejunal distension appears as the modality of choice for the diagnosis of a wide range of jejunal abnormalities. MDCT remains the first line imaging modalities because of an acute presentation in a substantial number of patients.

1. Gastro-bronchial fistula is a rare condition occurring most commonly as a complication of a subphrenic abscess. 2. Other causes include trauma and necrosis within an infiltrating neoplasm. 3. The treatment of those fistulae which are secondary to a subphrenic abscess should be by drainage of the abscess, jejunal tube feeding and continuous gastric aspiration.

Review
Surgery used to be the only therapy for gastric cancer, and since its ability to cure gastric cancer was the focus of attention, less attention was paid to function-preserving surgery in gastric cancer, though it was studied for gastroduodenal ulcer. Maki et al developed pylorus-preserving gastrectomy for gastric ulcer in 1967. At the same time, the definition of early gastric cancer (EGC) was being considered, histopathological investigations of EGC were carried out, and the validity of modified surgery was sustained. After the development of H2-blockers, the number of operations for gastroduodenal ulcers decreased, and the number of EGC patients increased simultaneously. As a result, the indications for pylorus-preserving gastrectomy for EGC in the middle third of the stomach extended, and various alterations were added. Since then, many kinds of function-preserving gastrectomies have been performed and studied in other fields of gastric cancer, and proximal gastrectomy, jejunal pouch interposition, segmental gastrectomy, and local resection have been performed. On the other hand, from the overall perspective, it can be said that endoscopic resection, which was launched at almost the same time, is the ultimate function-preserving surgery under the current circumstances. The current function-preserving gastrectomies that are often performed and studied are pylorus-preserving gastrectomy and proximal gastrectomy. The reasons for this are that these procedures that can be performed with systemic lymph node dissection, and they include three important elements: (1) reduction of the extent of gastrectomy; (2) preservation of the pylorus; and (3) preservation of the vagal nerve. In addition, these operations are more likely to be performed with a laparoscopic approach as minimally invasive surgery. Of the above-mentioned three elements, reduction of the extent of gastrectomy is the most important in our view. Therefore, we should try to reduce the extent of gastrectomy if curability of the gastric cancer can still be achieved. However, if we preserve a wider residual stomach in function-preserving gastrectomy, we should pay attention to the development of metachronous gastric cancer.

Digestive Surgery 2009To investigate if restoration of esophago-intestinal or esophago-gastric continuity with a jejunal pouch after total or proximal gastrectomy has clinical benefits. (Review)
Review
BACKGROUND/AIMS
To investigate if restoration of esophago-intestinal or esophago-gastric continuity with a jejunal pouch after total or proximal gastrectomy has clinical benefits.
METHODS
We reviewed all relevant reports published after 1990 that dealt with the clinical results of reconstruction with a jejunal pouch after total and proximal gastrectomies and correlated those findings with results for gastrointestinal motility. Reports were chosen from a search of the literature using PubMed.
RESULTS
After total gastrectomy, the benefit of a jejunal J pouch interposition was not apparent compared to simple jejunal interposition; indeed, one trial concluded that simple interposition was better than pouch interposition in terms of food intake. In contrast, results with a jejunal J pouch during Roux-en-Y (RY) type reconstruction were better than with conventional RY reconstruction in terms of food intake, nutritional status, body weight (BW) and symptoms. Advantages were also shown for a jejunal pouch with an inverted U shape interposed between the esophagus and residual stomach after proximal gastrectomy. Reconstruction using a jejunal pouch after proximal gastrectomy was better than esophagogastrostomy or simple jejunal interposition in terms of food intake, BW and symptoms. There were not enough data to conclude any benefits of a jejunal J pouch between the gastric remnant and the duodenum after distal gastrectomy.
CONCLUSIONS
Clinical results of restoration of intestinal continuity with a jejunal pouch after total and proximal gastrectomies may be attributed, at least in part, to the relationship between the motor activity of the gastric remnant, duodenum and jejunal pouch.

BACKGROUND
Free jejunal transfer for pharyngoesophageal reconstruction has often been criticized for its associated donor-site morbidity. Conversely, the same argument has been invoked to support use of fasciocutaneous flaps, given their low incidence of donor-site complications. The purpose of the current study was to document donor-site complication rate with free jejunal flaps for pharyngoesophageal reconstruction, in the hands of an experienced surgeon.
METHODS
A retrospective chart review was performed for consecutive patients who underwent free jejunal transfer between 1992 and 2012 by the senior author (P.G.C.). Demographic data, abdominal complications, surgical characteristics of small bowel anastomoses, and postoperative bowel function were specifically noted.
RESULTS
Overall, 92 jejunal flap reconstructions were performed in 90 patients. The mean follow-up time was 29 months. Twelve (13%) patients had prior abdominal surgery. Donor-site complications included ileus (n = 2), wound cellulitis (n = 1), wound dehiscence (n = 1), and small bowel obstruction (n = 1). Mean time to initiation of tube feeds after reconstruction was 5 days. A total of 77 (86.5%) patients were discharged on an oral diet. The perioperative mortality rate of 2% was not associated with any donor-site complication.
CONCLUSION
Free jejunal transfer is associated with minimal and acceptable donor-site complication rates. The choice of flap for pharyngoesophageal reconstruction should be determined by the type of defect, potential recipient site complications, and the surgeon's familiarity with the flap. Potential donor-site complications should not be a deterrent for free jejunal flaps given the low rate described in this study.

Review
PURPOSE OF REVIEW
Small intestinal neuroendocrine neoplasms (siNENs) are slowly growing tumours with a low malignant potential. However, more than half of the patients present with distant metastases (stage IV) and nearly all with locoregional lymph node (LN) metastases at the time of surgery. The value of locoregional treatment is discussed controversially.
RECENT FINDINGS
In stage I to III disease, locoregional surgery was currently shown to be curative prolonging survival. In stage IV disease, surgery may prolong survival in selected patients with the chance to cure locoregional disease besides radical/debulking liver surgery. It may improve the quality of life and may prevent severe local complications resulting in a state of chronic malnutrition and severe intestinal ischaemia or bowel obstruction. Locoregional tumour resection offers the opportunity to be curative or to focus therapeutically on liver metastasis, facilitating various other therapeutic modalities. Risks and benefits of the surgical intervention need to be balanced individually.

Meta-Analysis Review
BACKGROUND
Additional studies comparing several reconstruction methods after proximal gastrectomy have been published; of note, it is necessary to update systematic reviews and meta-analysis from the current evidence-based literature.
AIM
To expand the current knowledge on feasibility and safety, and also to analyze postoperative outcomes of several reconstructive techniques after proximal gastrectomy.
METHODS
PubMed, Google Scholar, and Medline databases were searched for original studies, and relevant literature published between the years 1966 and 2019 concerning various reconstructive techniques on proximal gastrectomy were selected. The postoperative outcomes and complications of the reconstructive techniques were assessed. Meta-analyses were performed using Rev-Man 5.0. A total of 29 studies investigating postoperative outcomes of double tract reconstruction, jejunal pouch interposition, jejunal interposition, esophagogastrostomy, and double flap reconstruction were finally selected in the quantitative analysis.
RESULT
Pooled incidences of reflux esophagitis for double tract reconstruction, jejunal pouch interposition, jejunal interposition esophagogastrostomy, and double flap reconstruction were 8.6%, 13.8%, 13.8%, 19.3%, and 8.9% respectively. Meta-analysis showed a decreased length of hospital in the JI group as compared to the JPI group (heterogeneity: Chi = 1.34, df = 1 (P = 0.25); I = 26%, test for overall effect: Z = 2.22 (P = 0.03). There was also a significant difference between JI and EG in length of hospital stay with heterogeneity: Chi = 1.40, df = 3 (P = 0.71); I = 0%, test for overall effect: Z = 5.04 (P < 0.00001). Operative time was less in the EG group as compared to the JI group (heterogeneity: Chi = 31.09, df = 5 (P < 0.00001); I = 84%, test for overall effect: Z = 32.35 (P < 0.00001).
CONCLUSION
Although current reconstructive techniques present excellent anti-reflux efficacy, the optimal reconstructive method remains to be determined. The double flap reconstruction proved to lower the rate of complication, but the DTR, JI, JPI, and EG groups showed higher incidence of complications in anastomotic leakage, anastomotic stricture, and residual food. In the meta-analysis result, the complications between the JI, JPI, and EG were comparable but the EG group showed to have better postoperative outcomes concerning the operative time, blood loss, and length of hospital stay.

BACKGROUND
Implementing a prospective lymphadenectomy protocol, we investigated the nodal yields and metastases per anatomical stations and nodal echelon following upfront pancreatoduodenectomy (PD) for cancer. Next, the relationship between the extension of nodal dissection, the number of examined and positive nodes (ELN/PLN), disease staging and prognosis was assessed.
METHODS
Lymphadenectomy included stations 5, 6, 8a-p, 12a-b-p, 13, 14a-b, 17, and jejunal mesentery nodes. Data were stratified by N-status, anatomical stations, and nodal echelons. First echelon was defined as stations embedded in the main specimen and second echelon as stations sampled as separate specimens. Recurrence and survival analyses were performed by using standard statistics.
RESULTS
Overall, 424 patients were enrolled from June 2013 through December 2018. The median number of ELN and PLN was 42 (interquartile range [IQR] 34-50) and 4 (IQR 2-8). Node-positive patients were 88.2%. The commonest metastatic sites were stations 13 (77.8%) and 14 (57.5%). The median number of ELN and PLN in the first echelon was 28 (IQR 23-34) and 4 (IQR 1-7). While first-echelon dissection provided enough ELN for optimal nodal staging, the aggregate rate of second-echelon metastases approached 30%. Nodal-related factors associated with recurrence and survival were N-status, multiple metastatic stations, metastases to station 14, and jejunal mesentery nodes.
CONCLUSIONS
First-echelon dissection provides adequate number of ELN for optimal staging. Nodal metastases occur mostly at stations 13/14, although second-echelon involvement is frequent. Only station 14 and jejunal mesentery nodes involvement was prognostically relevant. This latter station should be included in the standard nodal map and analyzed pathologically.
