[Unformed conglomerate debilitating jejunal fistulas and their two-stage surgical treatment via posterolateral laparotomy]. / Nesformirovannye konglomeratnye istoshchayushchie toshchekishechnye svishchi i ikh dvukhetapnoe khirurgicheskoe lechenie iz zadnebokovogo laparotomnogo dostupa.

OBJECTIVE: To create a method of two-stage repair of high unformed conglomerate delimited debilitating jejunal fistulas via posterolateral laparotomy with low risk of surgical complications. MATERIAL AND METHODS: Methodology and treatment outcomes were analyzed in 37 patients with unformed conglomerate high debilitating delimited jejunal fistulas. Of these, 22 patients underwent one-stage treatment through 2 converging incisions and/or two-stage treatment through anterolateral access. They made up a control group. Fifteen patients in the main group underwent two-stage treatment via posterolateral left-sided laparotomy with unilateral disconnection of jejunum with fistula. In most patients of both groups, fistulas complicated surgery for acute adhesive intestinal obstruction. Topography of adhesions that caused acute intestinal obstruction in both groups was studied in 172 other patients. Identical jejunal fistulas and two different surgical approaches made it possible to consider our groups representative. RESULTS: Two-stage treatment via posterolateral left-sided laparotomy reduced mortality from 63.6±10.2% to 20.0±10.3% (t=11.8; p<0.001). This approach simplified intraoperative diagnostics that became more informative. Posterolateral access increased the quality of anastomosis and safety of viscerolysis. CONCLUSION: A new two-stage approach with posterolateral left-sided laparotomy allowed atraumatic imposing of inter-intestinal anastomosis with proximal disconnection of jejunal fistula. This exclusion turns the fistula into analogue of the definitive Meidl's jejunostomy, unloads the intestinal anastomosis and increases the quality of suture. New strategy reduced the risk of complications and mortality.

Single anastomosis sleeve ileal bypass a single anastomosis sleeve jejunal bypass in the surgical treatment of severe obesity.

Bariatric surgery has been proven to be an effective method in the treatement of morbid obesity. The ideal bariatric procedure should be effective, easy to perform and safe. Sleeve gastrectomy and RYGB currently represent the most frequently used bariatric/metabolic procedures. However, they have a certain percentage of complications and post-operative morbidity and also they fail in some patients. These facts lead to the development of new surgical procedures, which also include single anastomosis sleeve ileal bypass (SASI) and single anastomosis sleeve jejunal bypass (SASJ). These procedures combines the advantages of restrictive and malabsorptive operations at the same time reducing the risk of nutrient deficiencies by maintaining passage through all the alimentary tract. The results so far are encouraging, further research and especially longer-term results are necessary.

[A Case of the Huge GIST in the Transverse Colon Mesentery with Intra-Tumoral Hemorrhage and Jejunal Infiltration].

A 38-year-old woman was admitted to our hospital due to severe anemia. CT showed a 13×12 cm tumor with moderately enhanced wall thickening in the right upper abdomen. The huge tumor located adjacent to the jejunum and compressed the right transverse colon. Hemorrhagic necrosis and air were observed within the tumor, suspecting tumor penetration into the jejunum. The patient was diagnosed with abdominal GIST with jejunal infiltration. Laparotomy revealed a 13× 11 cm solid mass with intra-tumoral hemorrhage and invasion into the jejunum, located in the transverse mesocolon. Tumor resection combined with partial jejunectomy and transverse colectomy were performed. Immunohistochemical findings of the resected specimen was positive for c-kit and DOG-1, and the MIB-1 positive rate was 10%. Three weeks after the operation, re-anastomosis was performed due to transverse colon anastomotic stricture. She was discharged 45 days after first operation. Currently, 9 months after the operation, patient has been prescribed imatinib and is alive without recurrence.

Long-term Results of Duodeno-jejunal Bypass in the Treatment of Obesity and Type 2 Diabetes.

PURPOSE: Obesity and its related severe comorbidities are increasing rapidly. The duodenal-jejunal bypass is an endoscopically implanted device (mimicking the Roux-en-Y gastric bypass) developed to support weight reduction and improve type 2 diabetes control. MATERIALS AND METHODS: Retrospective data analysis of consecutive patients undergoing duodenal-jejunal bypass (EndoBarrier®, DJB) implantation between 2013 and 2017 was performed to evaluate safety as well as short- and long-term efficacy. RESULTS: One hundred and twenty-one patients (mean BMI of 43.1 ± 7.2 kg/m2 and weight of 138.2 ± 28.6 kg) underwent DJB implantation. The mean dwelling time was 15.5 months, the mean total body weight loss (%TBWL) after explantation was 10.3% ± 7.9% (14.2 kg, p < 0.0001), and the mean BMI was 39.5 ± 7.3 kg/m2 (p < 0.0001). There was no significant weight gain 24 months after the explantation. Seventy-seven patients had type 2 diabetes mellitus (T2DM) with a mean HbA1c before implantation of 5.6% (n = 52). The mean HbA1c after explantation was 5.1% (p = 0.0001). Significant reductions in transaminase and lipid levels before and after explantation were observed. One complication occurred during implantation and another during explantation. In 16 patients, the device had to be extracted earlier than expected (7 for severe adverse events and 9 for adverse events; 13.2%). CONCLUSION: Despite an evident rate of adverse events, the DJB shows promise as a weight-loss procedure. Our results show that some patients implanted with the device maintained reduced weight even 24 months after explantation, while many improved T2DM control.

The Significance of Bile in the Biliopancreatic Limb on Metabolic Improvement After Duodenal-Jejunal Bypass.

INTRODUCTION: Duodenal-jejunal bypass (DJB) is an experimental procedure in metabolic surgery that does not have a restrictive component. Changes in bile acid (BA) dynamics and intestinal microbiota are possibly related to metabolic improvement after DJB. Our previous studies involving obese diabetic rats showed the crucial role of the biliopancreatic limb (BPL) in metabolic improvement after DJB caused by BA reabsorption. We established a new DJB procedure to prevent bile from flowing into the BPL and aimed to elucidate the importance of bile in the BPL after DJB. METHODS: Otsuka Long-Evans Tokushima Fatty rats with diabetes were divided into three groups: two DJB groups and a sham group (n = 11). Duodenal-jejunal anastomosis was performed proximal to the papilla of Vater in the DJB group (n = 11). However, the DJB-D group (n = 11) underwent a new procedure with duodenal-jejunal anastomosis distal to the papilla of Vater for preventing bile flow into the BPL. RESULTS: Glucose metabolism improved and weight gain was suppressed in the DJB group, but not in the DJB-D and sham groups. Serum BA level and conjugated BA concentration were elevated in the DJB group. The gut microbiota was altered only in the DJB group; the abundance of Firmicutes and Bacteroidetes decreased and that of Actinobacteria increased. However, the DJB-D group exhibited no apparent change in the gut microbiota, similar to the sham group. CONCLUSION: BAs are essential in the BPL for metabolic improvement after DJB; they can improve the gut microbiota in these processes.

[Modified reverse puncture technique for esophagojejunostomy during totally laparoscopic total gastrectomy for gastric cancer].

Objective: To evaluate the value of implementing a modified reverse puncture procedure for esophagojejunostomy during totally laparoscopic total gastrectomy. Methods: This was a descriptive case series. Relevant clinical data, including the operative procedure, recovery, and pathological findings of 35 patients with gastric cancer who had undergone esophagojejunostomy with a modified reverse puncture technique during totally laparoscopic total gastrectomy in the Department of Gastrointestinal Surgery, Fujian Provincial Hospital, from June 2022 to January 2023, were prospectively collected and retrospectively analyzed. The age of all patients in the group was (64.9±8.0) years old, with 22 males (62.9%) and a body mass index of (23.2±2.4) kg/m2. The tumors were located in the upper and middle parts of the stomach in 24 cases (68.6%) and in the junction of the esophagus and stomach in 11 cases (31.4%). Important technical aspects of the modified reverse puncture procedure are as follows. (1) Site of the esophageal incision: a transverse incision is made across the right lateral wall of the esophagus at the expected site of esophageal disjunction. (2) Technique for inserting an anvil: after threading a silk thread through the tip of anvil, the end of the thread is knotted and fixed as the traction thread, after which an anvil is inserted into the esophagus through the esophageal incision, leaving the end of the traction line exposed. Next, a 60-mm linear cutter is placed through the right midclavicular trocar to straighten the opened esophagus vertically, after which the rod of the anvil is pulled out of a small incision that has been made in the esophagus by pulling the traction thread, thus completing anvil placement. (3) Jejunal binding: the jejunum on the central bar of the stapler is fastened with silk thread to the stump of the jejunum, and then tied to the output loop of the jejunum with a gauze strip. Results: All 35 surgeries were successful, with no mortality or conversion to laparotomy. The operation time, anvil insertion time, and digestive tract reconstruction time were (232.7±34.4), (8.5±1.4), and (40.5±4.8) minutes, respectively. The intraoperative blood loss was 100 (20-250) mL and the incision was (5.3±0.9) cm long. The upper surgical margin was negative in all patients and the mean distance between the upper and tumor margins was (3.5±1.2) cm. The mean number of lymph nodes dissected per patient was 33.9±7.1. The times to initial ambulation, initial passage of flatus , postoperative fluid intake, and length of postoperative hospital stay were (3.2±1.1), (3.7±1.5), (4.6±2.3), and (9.8±3.2) days, respectively. Postoperative complications occurred in five patients: one case of anastomotic leak, two of anastomotic stenosis, one of pulmonary infection, and one of incomplete intestinal obstruction, all of which were successfully managed conservatively. Conclusion: Esophagojejunostomy using a modified reverse puncture technique during totally laparoscopic total gastrectomy is safe and feasible for gastric cancer, requiring only a small incision and achieving higher upper esophageal resection margins and good postoperative recovery, and therefore warrants further implementation.

Intestinal Atresias: A Ten-Year Evaluation of Outcomes.

INTRODUCTION: Intestinal atresia is a common cause of neonatal bowel obstruction. Atresias are often associated with other congenital anomalies. The purpose of the study was to evaluate associated anomalies, operative management, and postoperative outcomes of infants with intestinal atresia. METHODS: A review of patients presenting to a single free-standing children's hospital from March 2012 through February 2022 was performed. The variables examined were type of atresia, additional congenital anomalies, type of operative intervention, and postoperative outcomes. Standard statistical methods were utilized. RESULTS: A total of 75 patients with intestinal atresia were identified and several of these patients had multiple atresias. Isolated duodenal atresia patients were the most common (49.3%), followed by jejunal (32%) and ileal (12%). Mixed atresias were rare at 4%, with isolated pyloric and colonic also rare at 1.3% each. Malrotation was associated with 13% of patients and equally associated with duodenal and jejunoileal atresias. A low percentage (3%) of intestinal atresias was seen in conjunction with gastroschisis and concomitant malrotation. A majority of infants with duodenal atresia underwent standard duodenoduodenostomy (19% laparoscopic, 81% open). In infants with jejunoileal atresia, most underwent resection with primary anastomosis. A tapering enteroplasty was performed primarily in 13% of atresias. There were no significant differences noted in time to first feed or length of stay between those with and without tapering enteroplasty. Eleven percent of patients required subsequent intervention for stricture or small bowel obstruction. There was one death in this series. CONCLUSIONS: Consistent with other literature, duodenal atresia was the most common type of intestinal atresia. However, we demonstrated that malrotation was equally associated with duodenal and jejunoileal atresias while prior reports had shown a higher association with duodenal atresia. In our patient population, the use of tapering enteroplasty did not appear to be associated with outcomes. Overall, these infants have a low morbidity and mortality rate with a rare need for reoperation.

Second free jejunum transfer after flap loss does not affect oral intake: A retrospective case-control study.

PURPOSE: Free jejunum transfer is one of the standard procedures for restoring oral intake after total pharyngo-laryngo-esophagectomy. Flap loss leading to a second free jejunum transfer rarely occurs. This study investigated the impact of a second free jejunum transfer on post-operative oral intake. METHODS: A retrospective review was conducted on patients who underwent a first free jejunum transfer between July 1998 and December 2019. A total of 367 patients were included in the study. Among them, 17 patients who underwent a second free jejunum transfer because necrosis constituted the second free jejunum transfer group, whereas 350 patients who did not require a second free jejunum transfer formed the first free jejunum transfer group. The incidence of dysphagia requiring tube feeding and post-operative complications was compared between the two groups. Moreover, risk factors for dysphagia and complications were estimated. RESULTS: There were no statistically significant differences in the incidence of dysphagia post-operation between the two groups. A second free jejunum transfer was a statistically significant factor for complications at 2- and 6-months post-operation; however, there were no significant differences in complication rates at the 12-month follow-up. Furthermore, there were no significant differences in the incidence of severe complications between the two groups. CONCLUSION: Although a second free jejunum transfer increases early complications, it is not associated with major complications and does not negatively impact oral intake. These findings support the conclusion that free jejunum transfer is safe and helps maintain post-operative quality of life.

Gastrointestinal thickness, duration, and leak pressure of five intestinal anastomosis techniques in cats.

OBJECTIVE: To compare time to construct completion and resistance to leakage for five intestinal anastomosis techniques in cats and to report normal feline gastrointestinal thickness. STUDY DESIGN: Experimental study. SAMPLE POPULATION: Grossly normal intestinal segments (n = 120) from 10 fresh cat cadavers. METHODS: A total of 8 cm segments of fresh feline cadaveric intestine were collected, and mural thickness was recorded. Segments were randomly allocated between a control group (n = 20 segments) and five treatment groups (20 segments/group with 2 segments/construct = 10 constructs per group): (1) hand-sewn anastomosis - simple interrupted (HSA-SI), (2) hand-sewn anastomosis - simple continuous (HSA-SC), (3) functional end-to-end stapled anastomosis (FEESA), (4) functional end-to-end stapled anastomosis with oversew (FEESA-O), (5) skin stapled anastomosis (SS). Time to construct completion, leakage location, initial leak pressure (ILP), and maximum intraluminal pressure (MIP) were compared. RESULTS: Mean mural thickness ± SD (mm) for the stomach, duodenum, jejunum, and ileum were 1.66 ± 0.28, 2.05 ± 0.18, 2.28 ± 0.30, and 2.11 ± 0.39, respectively. ILPs (mean ± SD) for HSA-SI (165 ± 122 mmHg), HSA-SC (149 ± 83), FEESA-O (63 ± 25, FEESA (84 ± 59), SS (77 ± 56), and control segments (>500) were compared. There was no statistically significant difference in ILP (p > .08) or MIP (p > .084) between any treatment groups. Nonoversewn FEESAs were 2.4 times faster to perform compared to oversewn FEESA and SS groups, and 4.7 times faster than HSA (p < .001). CONCLUSION: All anastomosis techniques provide resistance to leakage that is supraphysiological to that of the normal maximum intraluminal pressure. HSA take longer to complete than stapled anastomoses. CLINICAL SIGNIFICANCE: All anastomotic techniques may be appropriate in cats. Hand-sewn anastomoses result in a longer surgical time.

Effects of cyanoacrylate on leakage pressures of cooled canine cadaveric jejunal enterotomies.

OBJECTIVE: To compare the intraluminal initial and maximal pressures of enterotomies closed using three different techniques (single-layer appositional continuous closure; closure with cyanoacrylate; a single-layer appositional closure augmented with cyanoacrylate) in a cooled canine cadaveric jejunal model and to report the initial leak location in all samples. STUDY DESIGN: Experimental, ex-vivo study. SAMPLE POPULATION: Grossly normal chilled small intestine segments from three canine cadavers. METHODS: A total of 45 chilled jejunal segments (n = 15 segments/group) were assigned to a handsewn group (HSE), a cyanoacrylate only group (CE) and a handsewn and cyanoacrylate group (HS + CE). A 2 cm antimesenteric enterotomy was performed and closure with one of the above techniques. Initial leakage pressures (ILP), maximal intraluminal pressures (MIP) and initial leakage location were recorded by a single observer. RESULTS: Handsewn enterotomies leaked at higher ILP when augmented with cyanoacrylate (83.3 ± 4.6 mmHg, p < .001) compared to both the HSE group (43.8 ± 5.3 mmHg) and the CE group (18.6 ± 3.5 mmHg). Those sealed with cyanoacrylate only leaked at a lower MIP compared with the other groups (p < .001). Maximal intraluminal pressures did not differ between handsewn enterotomies, whether augmented or not (p = .19). CONCLUSION: Reinforcement of a sutured enterotomy closure with cyanoacrylate was easy to perform and resulted in significantly increased initial leak pressures in cadaveric jejunum. CLINICAL SIGNIFICANCE: The increased leakage pressures achieved by reinforcing enterotomies with cyanoacrylate could consequently reduce the incidence of postoperative intestinal leakage following an enterotomy and may result in reduced patient morbidity or mortality.

The Sleeve Gastrectomy with Jejunal Bypass (Original Technique).

Introduction: Sleeve gastrectomy with jejunal bypass (SGJB) has been used as a bariatric/metabolic procedure since 2003, in the search for a simpler than other standard techniques and as effective as them. The jejunal-ileal anastomosis can deliver food directly to the hindgut where incretins are secreted. This procedure has gained popularity around the globe and has been studied in rat models as in humans, especially in South America and Asia. In this review, we present the details of the original surgical technique SGJB, summarized all the publications of the procedure, discuss possible advantages and disadvantages, and provide scientific information to look for the real place between bariatric/metabolic procedures. Methods: With 20 years of experience performing the original SGJB, the authors present the details of the procedure. Results: The SGJB consists of a traditional sleeve with the addition of a jejunal bypass. The jejunum is transected 20-30 cm distally to the ligament of Treitz. Then, the biliopancreatic limb is anastomosed to restore transit 250-300 cm distal to the jejunum transection. This way, the ileum gets in contact with partially digested food with the subsequent production of incretins. Conclusion: In this article, we describe the original Alamo technique of SGJB. It is important to clarify the technical details since many publications have presented different lengths of the defunctionalized jejunal limb. Also, the SGJB has been categorized in the "sleeve plus" procedures and its promising outcomes should rapidly position it as an alternative metabolic surgery.

A Modified Purse-String Stapling Technique for Intracorporeal Circular Stapled Esophagojejunostomy During Laparoscopic Total Gastrectomy: Comparison with Extracorporeal Reconstruction Technique.

Background: Intracorporeal esophagojejunostomy (EJ) in the context of laparoscopic total gastrectomy remains a complex and technically demanding procedure. We have previously introduced a novel method of intracorporeal circular stapled EJ utilizing a conventional purse-string suture instrument. Since May 2018, we have refined this technique, and the aim of this study was to assess its safety and efficacy. Methods: Between May 2018 and June 2022, we enrolled 92 patients who underwent laparoscopic total gastrectomy with the modified intracorporeal reconstruction method. In addition, between March 2014 and June 2022, we enrolled 121 patients who underwent the procedure with the extracorporeal reconstruction method. We retrospectively collected and compared the clinical data of these 2 patient cohorts. Results: Intracorporeal reconstruction group experienced lower postoperative pain scores (2.7 ± 1.3 versus 4.5 ± 1.4, P = .032), reduced administration of analgesics (3.1 ± 2.2 versus 5.0 ± 3.5, P = .041), and shorter postoperative hospital stays (4.9 ± 2.3 versus 6.3 ± 3.5, P = .045) compared with the extracorporeal reconstruction group. In addition, anastomotic time and postoperative pain score were not increased in the overweight patients in the intracorporeal reconstruction group. Anastomotic leakage occurred in 2 (2.2%) patients in the intracorporeal reconstruction group and 4 (3.3%) patients in the extracorporeal reconstruction group. Anastomotic stricture occurred in 1 (1.1% and 0.8%) patient in each group. There was no significant difference in the overall postoperative complication rate between the 2 groups. Conclusions: The modified intracorporeal purse-string stapling technique for EJ during laparoscopic total gastrectomy is a safe and viable option, exhibiting less invasiveness and comparable outcomes to the extracorporeal reconstruction method, especially suitable for obese patients.

Using video-based assessment (VBA) to document fellow improvement in safely completing the jejunojejunostomy portion of laparoscopic Roux-en-Y gastric bypass (RYGB) surgery.

BACKGROUND: Surgical assessment instruments are used for formative and summative trainee evaluations. To characterize the features of existing instruments and a novel 12-item objective, procedure-specific assessment tool for Roux-en-Y Gastric Bypass (RYGB-OPSA), we evaluated the progress of a single surgical fellow over 17 consecutive surgeries. METHODS: Seventeen consecutive RYGB videos completed between 8/2021 and 1/2022 by an academic hospital surgical fellow were de-identified and assessed by four board-certified bariatric surgeons using Global Operative Assessment of Laparoscopic Skills (GOALS), General Assessment of Surgical Skill (GASS), and RYGB-OPSA which includes the reflection of transverse colon, identification of ligament of Treitz, biliopancreatic and Roux limbs orientation, jejunal division point selection, stapler use, mesentery division, bleeding control, jejunojejunostomy (JJ) anastomotic site selection, apposition of JJ anastomotic site, JJ creation, common enterotomy closure of JJ, and integrity of anastomosis. The GASS measured economy of motion, tissue handling, appreciating operative anatomy, bimanual dexterity, and achievement of hemostasis. RYGB-OPSA and GASS items were scored "poor-unsafe," "acceptable-safe," or "good-safe." Change in performance was measured by linear trendline slope. RESULTS: Over the course of 17 procedures, significant improvement was demonstrated by three GOALS items, GOALS overall score, GASS bimanual dexterity, and three RYGB-OPSA tasks: JJ creation, jejunal division point selection, and stapler use. Achievement of hemostasis declined but never rated "poor-unsafe." Overall RYGB-OPSA and GOALS trendlines documented significant increase across the 17 procedures. CONCLUSION: This examination of a bariatric surgery fellow's operative training experience as measured by three surgical assessment instruments demonstrated anticipated improvements in general skills and safe completion of procedure-specific tasks. Effective surgical assessment instruments have enough sensitivity to show improvement to enable meaningful trainee feedback (low-stakes assessments) as well as the ability to determine safe surgical practice to enable promotion to greater autonomous practice.

Bariatric surgery alters mitochondrial function in gut mucosa.

BACKGROUND: The obesity pandemic has worsened global disease burden, including type 2 diabetes, cardiovascular disease, and cancer. Metabolic/bariatric surgery (MBS) is the most effective and durable obesity treatment, but the mechanisms underlying its long-term weight loss efficacy remain unclear. MBS drives substrate oxidation that has been linked to improvements in metabolic function and improved glycemic control that are potentially mediated by mitochondria-a primary site of energy production. As such, augmentation of intestinal mitochondrial function may drive processes underlying the systemic metabolic benefits of MBS. Herein, we applied a highly sensitive technique to evaluate intestinal mitochondrial function ex vivo in a mouse model of MBS. METHODS: Mice were randomized to surgery, sham, or non-operative control. A simplified model of MBS, ileal interposition, was performed by interposition of a 2-cm segment of terminal ileum into the proximal bowel 5 mm from the ligament of Treitz. After a four-week recovery period, intestinal mucosa of duodenum, jejunum, ileum, and interposed ileum were assayed for determination of mitochondrial respiratory function. Citrate synthase activity was measured as a marker of mitochondrial content. RESULTS: Ileal interposition was well tolerated and associated with modest body weight loss and transient hypophagia relative to controls. Mitochondrial capacity declined in the native duodenum and jejunum of animals following ileal interposition relative to controls, although respiration remained unchanged in these segments. Similarly, ileal interposition lowered citrate synthase activity in the duodenum and jejunum following relative to controls but ileal function remained constant across all groups. CONCLUSION: Ileal interposition decreases mitochondrial volume in the proximal intestinal mucosa of mice. This change in concentration with preserved respiration suggests a global mucosal response to segment specific nutrition signals in the distal bowel. Future studies are required to understand the causes underlying these mitochondrial changes.

Jejunal or Ileal Exocrine Drainage in Pancreas Transplantation: Impact on Gastrointestinal Function.

OBJECTIVES: Pancreas transplant can have serious complications requiring salvage pancreatectomy, and surgical approaches should be carefully considered, with jejunal or ileal anastomoses most often employed. The jejunum may reduce gastrointestinal disturbance, whereas the ileum is more immunogenic. Proximal gastrointestinal anastomoses pose challenges with salvage pancreatectomy and creation of high-output stoma, often in the context of end-stage renal failure. Here, we compared outcomes between these techniques. MATERIALS AND METHODS: We retrospectively analyzed patient records of simultaneous pancreas and kidney transplants at a single center between 2013 and 2015, with follow-up to 2020. RESULTS: Our center performed 86 simultaneous pancreas and kidney transplants during the study period; 10 patients were excluded because of incomplete records of anastomosis type. Of included recipients, 59.2% were men (mean age 41.5 ± 8.4 y), 72.4% were donors after brain death, and 98.7% had received a first pancreas transplant. Forty-three simultaneous pancreas and kidney transplants were performed with ileal anastomosis and 33 with jejunal anastomosis. We found no significant differences in recipient or donor factors or immunosuppression regimen between anastomosis groups and no significant differences in overall patient, pancreas, or kidney graft survival or in gastrointestinal complications. Hospital length of stay was higher with ileal anastomosis (median 14 vs 19 days; P < .05), as was cold ischemic time (median 8:48 vs 9:31 hours; P < .05). Three patients required salvage pancre-atectomy and loop ileostomy formation with multiorgan support, prolonged intensive care unit stay, relaparotomy, and/or laparostomy. CONCLUSIONS: Long-term outcomes were comparable between our patient groups. Catastrophic complica-tions occur in a minority of cases, requiring salvage surgery. More complications occurred with ileal anastomosis, but this approach allows graft pancreatectomy and formation of loop ileostomy, avoiding a more proximal stoma in clinically unstable patients. Further studies are needed to examine the impact of enteric anastomosis site.

Radiographic and ultrasonographic appearance of a jejunal torsion-volvulus in a dog.

A 1.5-year-old male neutered, 5 kg, Dachshund was referred for anorexia and vomiting for several days' duration. Radiographs revealed concern for a small intestinal obstruction. Ultrasonography revealed a severely distended segment of jejunum containing echogenic fluid that abruptly narrowed, twisted, and transitioned into normal jejunum, along with the presence of a distinct "whirl sign" that resulted from the intestinal segments twisting around themselves. This, in addition to the absence of flow on power Doppler interrogation, was compatible with a focal jejunal torsion-volvulus. The torsion-volvulus was surgically confirmed, a resection and anastomosis was performed, and the dog recovered uneventfully.
