    Abstract: 〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 Sufficient tissue oxygenation is essential for anastomotic healing in visceral surgery. Hyperspectral imaging (HSI) is a noncontact, noninvasive technique for clinical assessment of tissue oxygenation in real time. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 In this case series, HSI was used in 4 patients who were admitted for either esophageal cancer or cardiac carcinoma (AEG type I or II). Thoraco-abdominal surgical esophageal resection was performed after staging and neoadjuvant therapy. Intraoperative oxygenation of superficial (StO 〈 sub 〉 2 〈 /sub 〉 ) and underlying tissue (NIR perfusion index) of the gastric sleeve were studied intrathoracic by means of the TIVITA® Tissue HSI camera. This was performed prior to esophagogastric anastomosis. The postoperative course, especially in view of surgical complications, was recorded. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Assessment of StO 〈 sub 〉 2 〈 /sub 〉 and NIR perfusion index was performed in 4 regions of interest per gastric sleeve, aboral and oral of the clinically determined resection line. It allowed the fast quantification of gastric oxygenation prior gastroesophageal anastomosis. Median StO 〈 sub 〉 2 〈 /sub 〉 aboral of the determined resection line was 69%, while median StO 〈 sub 〉 2 〈 /sub 〉 in the oral part of the gastric sleeve was found at 53%. In contrast, the median NIR perfusion index was similar aboral (80) and oral (82) of the resection line. In none of the 4 studied patients, an anastomotic failure appeared. 〈 b 〉 〈 i 〉 Discussion/Conclusion: 〈 /i 〉 〈 /b 〉 This report suggests that HSI is a feasible technique for intraoperative assessment of tissue oxygenation before gastroesophageal anastomosis and might reduce the incidence of anastomotic failure in the gastrointestinal tract.

    Abstract: 〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 Intestinal failure (IF) in the adult is the result of a wide spectrum of disease. Acute mesenteric ischemia, postoperative short bowel due to a complicative course, and Crohn’s disease are major causes of IF. Reconstructive surgery in the context of IF comprises a spectrum of procedures including stoma takedown, reversal of laparostomies, and closure of enteric fistulas. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 This article is based on a PubMed-based literature search and personal experience in adult patients with IF. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 This review summarizes therapeutic options of reconstructive surgery in adult patients focusing on the main reasons of IF such as mesenteric ischemia, complicative previous surgery, and Crohn’s disease. Indications and contraindications are discussed as well as the optimal time point of reconstructive surgery. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 This overview summarizes surgical aspects in a special cohort of patients with a rare disease entity necessitating an interdisciplinary approach.

    Abstract: We report the case of a 74-year-old female with abdominal pain, tarry stools, and tachycardia. Previous history included diabetes mellitus with micro- and macroangiopathy. Imaging revealed portal gas, left sided colitis, and emphysematous gastritis, besides severe atherosclerosis with subtotal celiac trunk occlusion and moderate stenosis of the inferior mesenteric artery. Upper endoscopy revealed findings consistent with focal necrotizing gastritis at the greater curvature and acute esophageal necrosis. Blood cultures immediately grew 〈 i 〉 Clostridium perfringens 〈 /i 〉 . The patient was treated with broad spectrum antibiotics and was discharged after 21 days in the hospital. This case demonstrates the rare coincident occurrence of nontransmural ischemia of the left colon, the esophagus, and the stomach as a result of low-flow circulatory compromise, which then precipitated 〈 i 〉 C. perfringens 〈 /i 〉 associated emphysematous gastritis and blood stream infection.

    Abstract: 〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 Acute mesenteric ischemia (AMI), either arterial or venous, is still a devastating disease with poor prognosis. It is unknown, whether AMI is associated with impaired quality of life (QoL) in long-term survivors. 〈 b 〉 〈 i 〉 Material and Methods: 〈 /i 〉 〈 /b 〉 This retrospective analysis includes 64 patients with occlusive arterial or venous mesenteric ischemia treated operatively between 2008 and 2016 at the University Medical Center Rostock. Short-term outcome with focus on comorbidities was measured by the Charlson comorbidity index (CCI) an instrument that operationally measures comorbidity based on 17 clinical parameters including age. Operative outcome in view of enterostomy placement and long-term outcome measured as QoL by the EQ-5D in the long-term survivors were evaluated. The EQ-5D is a standardized, self-reported five-dimension QoL questionnaire built to provide a simple and generic measure of health. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Thirty-day mortality was 60.9%, and in-hospital mortality was 70.3% ( 〈 i 〉 n 〈 /i 〉 = 45). No patient was discharged with a stoma. Patients with a primary anastomosis after the initial operation for AMI had a high leak rate of 27% (4/15 patients) compared to no dehiscence in the group of patients who had secondary anastomosis during second or third laparotomy. The long-term survivors had significantly lower CCI compared to the 45 nonsurvivors (median 4 [3, 4, 5, 6] vs. 6 [4, 5, 6, 7] ). All long-term survivors had QoL assessment. QoL score was significantly impaired compared to an age- and sex-matched reference population. This impairment was not due to disease-specific sequelae such as presence of stool deviation or intestinal failure but due to preexisting risk factors as shown by an inverse relation between the CCI and QoL score. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 Herein, we show for the first time that long-term QoL in patients with AMI is impaired but this impairment is not due to disease-specific aspects but rather general risk factors underlying the presence of a higher level of comorbidities at the time of AMI.

    Abstract: 〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 Anorectal surgery covers a wide spectrum of surgery. Diagnostic workup of anorectal disease is based on clinical examination with basic functional tests followed by more elaborate diagnostic tests. Since the incidence of anorectal disorders increases with age, more patients will present in outpatient clinics, thus underlining the relevance of this topic. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 A PubMed literature search was performed using the terms ‘anal incontinence', ‘anal and rectal surgery', ‘functional diagnostics', and combinations of these terms. No restriction regarding publication year or publication type was applied but randomized trials, ‘metanalyses', or guidelines were ranked higher. Only articles in English or German were included. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 The diagnostic value of digital rectal examination, anal manometry and endosonography, the water holding procedure, contrast enema, and incontinence scores is summarized. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 The article focusses on basic clinical and functional diagnostic tests which can be easily applied in the pre- and postoperative setting to evaluate the postoperative outcome.
