- Background: Bariatric procedures are increasingly being used, but data on bowel habits are scarce.Objectives: To assess changes in gastrointestinal function and patient-scored symptoms after Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion with duodenal switch (BPD/DS).Setting: University hospital in Sweden.Methods: We recruited 268 adult patients (mean age of 42.5 yr, body mass index 44.8, 67.9% female) listed for RYGB and BPD/DS. Patients answered validated questionnaires prospectively concerning bowel function, the Fecal Incontinence Quality of Life Scale, and the 36-Item Short Form Health Survey before and after their operation.Results: Postoperatively, 208 patients (78.2% of 266 eligible patients) answered the questionnaires. RYGB patients had fewer bowel motions per week (8 versus 10) and more abdominal pain postoperatively (P<.001). Postoperatively, the 35 BPD/DS patients (69% versus 23%) needed to empty their bowel twice or more than twice daily, reported more flatus and urgency, and increased need for keeping a diet (P<.001). Concerning Fecal Incontinence Quality of Life Scale, coping and behavior was slightly reduced while depression and self-perception scores were improved after RYGB. Lifestyle, coping and behavior, and embarrassment were reduced after BPD/DS (P<.05). In the 36-Item Short Form Health Survey, physical scores were markedly improved, while mental scores were largely unaffected.Conclusion: RYGB resulted in a reduced number of bowel movements but increased problems with abdominal pain. In contrast, BPD/DS-patients reported higher frequency of bowel movements, more troubles with flatus and urgency, and increased need for keeping a diet. These symptoms affected quality of life negatively, however, general quality of life was markedly improved after both procedures. These results will be of great value for preoperative counseling.

- SettingPrivate clinic, Stockholm, and nation-wide in-hospital care, Sweden.ObjectivesThe use of sleeve gastrectomy (SG) for treatment of morbid obesity has increased worldwide, but information about long-term outcome is still limited. Our objective was to evaluate the need for additional in-hospital care after SG for obesity (body mass index [BMI] >30) in 862 patients, all operated at a single center.MethodsTwo national registries, the Inpatient Registry and the Death Registry, were used to collect long-term data on in-hospital care, grouped by the International Statistical Classification of Diseases and Related Health Problems (ICD-10) and mortality, respectively.ResultsIn-hospital care for SG-operated females was decreased for four groups of obesity-related ICD-10 diagnoses: endocrine and metabolic diseases and circulatory, digestive, and genitourinary diseases, as well as injuries and poisoning (p<0.001 for all). However, female SG patients still required in-hospital care above the national level for women of corresponding ages.ConclusionsAlthough a significant reduction in in-hospital care was observed, SG patients did not reach national levels.

Esophageal- and Gastroesophageal Junctional Cancer : Aspects on Staging, Treatment and Results
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Esophageal- and gastroesophageal junctional (GEJ) cancer is the sixth cause of cancer-related death worldwide. Some improvements in care are attributed to nationwide disease-specific registries, preoperative staging and increased understanding of mechanisms affecting patient selection. Surgery, however, is a cornerstone for treatment where minimally invasive surgery and increased understanding of perioperative physiology may be beneficial. The aims of this thesis were to validate the Swedish national registry for esophageal and gastric cancer (NREV) and to explore mechanisms in patient selection, perioperative physiology, treatment-related outcomes and staging.A validation study with re-abstracted data on 400 patients determined NREV comparable to other similar registries and to have a completeness of 95.5 %. Overall accuracy was 91.1 % throughout the registry and timeliness to reporting was adequate.In a cohort of 4112 patients from NREV, high education level was associated with an increased probability of being allocated to curative treatment, as was the presence of a multidisciplinary treatment conference. High education level was associated with improved survival.By measuring intramucosal pH (pHi) in 32 patients, to describe perfusion in the gastric conduit during esophagectomy, a reduction in perfusion was seen at all surgical steps altering vascular supply to the conduit but foremost after gastric tube construction by linear stapling. Patients with low pHi on the first postoperative day were more prone to anastomotic insufficiency.In 116 patients undergoing esophagectomy (65 open and 51 minimally invasive), a retrospective cohort study regarding surgical oncological results and postoperative complications was conducted. Lymph node yield was increased, peroperative blood loss and in-hospital stay were reduced with minimally invasive esophagectomy. Postoperative complications were unaffected by surgical approach. In a prospective study of nineteen patients, whole-body integrated PET/MRI was compared to PET/CT in preoperative staging. PET/MRI was safe and feasible. Accuracy and correlations between modalities were good regarding tumor characteristics and N- and M-staging. In T-staging there were discrepancies indicating differences between modalities.The thesis presents data on the quality of NREV for future research and elaborates on patient selection, staging, perioperative physiology and treatment-related outcomes for patients with esophageal- and GEJ cancer.

- Background: Due to declining student ratings, a new teaching method was applied to a course in gastrointestinal diseases for undergraduate medical students. Problem-based learning was replaced with our new concept, consisting of a theory week with traditional lectures and case seminars.Methods: In this retrospective study, we compared student-ratings from the problem-based learning era to a new hybrid concept. The students evaluated the concepts by rating (1-6, 6 = best) nine different subject areas. Additional free text comments were possible. Teachers working with both concepts did likewise. Statistical differences between the two periods were studied by Mann Whitney U-test.Results: The study group consisted 621 students (57% females, total response rate of 52%). Scores for lectures (4.9 vs.3.8) and teaching stimulation and feedback (4.6 vs 3.6, and 3.7 vs 3.4, respectively), and to what extent the contents reflected learning goals (5.2 vs 4.3, p<0.05 for all) were instantly improved, which also prevailed in the following semesters. At the end of the study period, a significant improvement in case seminars (4.8 vs 4.3) and practical training (4.9 vs 3.8, p<0.05 for both) was seen. Free text answers revealed that the students felt more prepared for their clinical rotation. Teachers rated the new hybrid concept higher (4.7 vs 3.5, p<0.05) and especially praised the new lectures.Conclusion: The new learning concept resulted in both improved student-ratings and more satisfied teachers. We believe that the hybrid concept, combining lectures and case-seminars, facilitated learning and improved the learning climate. The subsequent uninterrupted practical training also received improved scores.
