RESUMO
This case report details a rare instance of a perforated jejunal gastrointestinal stromal tumor (GIST) in a 76-year-old female patient. The patient presented with acute abdominal pain and distension without any changes in bowel habits or episodes of nausea and vomiting. Initial diagnostics, including abdominal plain radiography and ultrasonography, were inconclusive; however, a computed tomography (CT) scan revealed pneumoperitoneum and an irregular fluid collection suggestive of small intestine perforations. Surgical intervention uncovered a 35 mm jejunal GIST with a 10 mm perforation. Histopathological examination confirmed a mixed cell type GIST with high malignancy potential, further substantiated by immunohistochemistry markers CD117, DOG1, and vimentin. Molecular analysis illuminated the role of key oncogenes, primarily KIT and PDGFRA mutations, emphasizing the importance of molecular diagnostics in GIST management. Despite the severity of the presentation, the patient's postoperative recovery was favorable, highlighting the effectiveness of prompt surgical and multidisciplinary approaches in managing complex GIST cases.
RESUMO
BACKGROUND: Nutritional administration in acute pancreatitis (AP) management has sparked widespread discussion, yet contradictory mortality results across meta-analyses necessitate clarification. The optimal nutritional route in AP remains uncertain. Therefore, this study aimed to compare mortality among nutritional administration routes in patients with AP using consistency model. METHODS: This study searched four major databases for relevant randomized controlled trials (RCTs). Two authors independently extracted and checked data and quality. Network meta-analysis was conducted for estimating risk ratios (RRs) with 95% confidence interval (CI) based on random-effects model. Subgroup analyses accounted for AP severity and nutrition support initiation. RESULTS: A meticulous search yielded 1185 references, with 30 records meeting inclusion criteria from 27 RCTs (n = 1594). Pooled analyses showed the mortality risk reduction associated with nasogastric (NG) (RR = 0.34; 95%CI: 0.16-0.73) and nasojejunal (NJ) feeding (RR = 0.46; 95%CI: 0.25-0.84) in comparison to nil per os. Similarly, NG (RR = 0.45; 95%CI: 0.24-0.83) and NJ (RR = 0.60; 95%CI: 0.40-0.90) feeding also showed lower mortality risk than total parenteral nutrition. Subgroup analyses, stratified by severity, supported these findings. Notably, the timing of nutritional support initiation emerged as a significant factor, with NJ feeding demonstrating notable mortality reduction within 24 and 48 h, particularly in severe cases. CONCLUSION: For severe AP, both NG and NJ feeding appear optimal, with variations in initiation timings. NG feeding does not appear to merit recommendation within the initial 24 h, whereas NJ feeding is advisable within the corresponding timeframe following admission. These findings offer valuable insights for optimizing nutritional interventions in AP.

PURPOSE: Although venous drainage of the jejunal loop may be maintained after sacrifice of jejunal vein tributaries during pancreatoduodenectomy, risk of severe jejunal mesenteric congestion following division of these tributaries can be difficult to predict. This study considered how best to predict safety of jejunal vein tributary dissection. METHODS: Preoperative imaging findings and results of intraoperative clamp tests of jejunal vein tributaries during pancreatoduodenectomy were analyzed in 121 patients with hepatobiliary and pancreatic disease to determine whether this information adequately predicted safety of resecting superior mesenteric vein branches. RESULTS: Jejunal vein tributaries caudal to the inferior border of the pancreatic uncinate process tended to be fewer when tributaries cranial to this landmark were more numerous. Tributaries cranial to the border drained a relatively wide expanse of jejunal artery territory in the jejunal mesentery. The territory of jejunal tributaries cranial to the inferior border of the pancreas did not vary according to course of the first jejunal vein branch relative to the superior mesenteric artery. One patient among 30 (3%) who underwent intraoperative clamp tests of tributaries cranial to the border showed severe congestion in relation to a venous tributary coursing ventrally to the superior mesenteric artery. CONCLUSION: Jejunal venous tributaries drained an extensive portion of jejunal arterial territory, but tributaries located cranially to the inferior border of the pancreas could be sacrificed without congestion in nearly all patients. Intraoperative clamp testing of these tributaries can identify patients whose jejunal veins must be preserved to avoid congestion.

BACKGROUND: Esophageal squamous cell carcinoma is characterized by field cancerization, wherein multiple cancers occur in the esophagus, head and neck, and stomach. Synchronous esophageal and colorectal cancers are also encountered with a certain frequency. A good prognosis can be expected if the tumors in both locations can be safely and completely removed. For patients with multiple cancers that occur simultaneously with esophageal cancer, it is necessary to perform a staged operation, taking into consideration the associated surgical invasiveness. It is also necessary to select multidisciplinary treatment depending on the degree of progression of the multiple lesions. We report our rare experience with a staged operation for a patient with synchronous advanced cancers of the esophagus and cecum who had previously undergone total gastrectomy with reconstruction by jejunal interposition for gastric cancer. CASE PRESENTATION: A 71-year-old man with a history of reconstruction by jejunal interposition after total gastrectomy was diagnosed as having multiple synchronous esophageal and cecal cancers. After neoadjuvant chemotherapy, we performed a planned two-stage operation, with esophagectomy and jejunostomy in the first stage and ileocecal resection and jejunal reconstruction with vascular anastomosis in the second. Postoperatively, the patient was relieved without major complications, and both tumors were amenable to curative pathologic resection. CONCLUSIONS: Our procedure reported here may be recommended as an option for staged resection and reconstruction in patients with simultaneous advanced esophageal and cecal cancer after total gastrectomy.

The intestinal microbiota plays a pivotal role in digestive processes and maintains gut health and intestinal homeostasis. These functions may be compromised by increased environmental heat, which in turn reduces feed intake and gut integrity and activates the intestinal immune system. It remains unknown whether high ambient temperatures, which cause heat stress (HS) in dairy cows, disturb the eubiosis of the microbial community, and if so, to which extent the reduction in feed intake and the impairment of circulating and intestinal metabolites account for the alterations of the jejunal microbiota. To address these questions, jejunal digesta, mucosa, and plasma samples were collected from cows exposed to heat stress (HS; 28°C, temperature-humidity index [THI] = 76, n = 10), control conditions (CON; 16°C, THI = 60, n = 10), or pair-fed (PF; 16°C, THI = 60, n = 10) for 7 d. Digesta fluids were examined for pH, acetate, nonesterified fatty acids (NEFA), glucose, and lactate, and plasma samples were analyzed for glucose, lactate, BHB, triglycerides, NEFA, creatinine, and urea. The microbiota of the digesta and mucosa samples were analyzed by 16S rRNA sequencing. The α-diversity was higher in mucosa than digesta but was not affected by high ambient temperatures. However, the mucosa-associated microbiota appeared more responsive to ambient heat than the digesta microbiome. The adaptive responses under HS conditions comprised an increased mucosal abundance of Bifidobacteriaceae, Succinivibrionaceae UCG-001, Clostridia and Lactobacillus. In the digesta, HS has exerted effects on microbial abundance of Colidextribacter, and Lachnospiraceae UCG-008. Several correlations between plasma or intestinal metabolites and microbiota were elucidated, including Methanobacteriaceae correlating positively with plasma BHB and digesta glucose concentrations. Moreover, the reduction in feed intake during HS had non-negligible effects on microbial diversity and the abundance of certain taxa, underpinning the importance of nutrient supply on maintaining intestinal homeostasis.

BACKGROUND: Bariatric surgery (BS) is an effective approach in treating obesity and ameliorating T2DM with obesity. Our previous studies demonstrated that duodenal-jejunal bypass (DJB) altered long non-coding RNAs (lncRNAs) in the gastrointestinal system, which is associated with modulation of lipid metabolism, and glycemic control through entero-pancreatic axis and gut-brain axis. The adipose non-coding RNA expression profile and the underlying competing endogenous RNA (ceRNA) regulatory network pattern post DJB needs further research and investigation. RESULTS: In this study, we compared the lncRNAs, circular RNAs (circRNAs) and messenger RNAs (mRNAs) expression in adipose tissues between the sham group and the DJB group. 2219 differentially expressed mRNAs (DEmRNAs), 722 differential expression of lncRNAs (DElncRNAs) and 425 differential expression of circRNAs (DEcircRNAs) were identified. GO terms and KEGG pathways analysis of the DEmRNAs implied that the dysregulated adipose mRNAs were associated with lipid, amino acid metabolism, insulin resistance, and extra cellular matrix (ECM)-related pathways. Moreover, via analyzing ceRNA regulatory networks of DElncRNAs and DEcircRNAs, 31 hub DE mRNAs, especially Mpp7, 9330159F19Rik, Trhde. Trdn, Sorbs2, were found on these pathways. CONCLUSIONS: The role of DJB in adipose tends to remodel ECM and improve the energy metabolism through the ceRNA regulatory network.

Pancake kidney is a renal fusion anomaly with only a few reported prenatal diagnoses. Other structural anomalies beyond the urogenital system may also be associated. This study describes a dual anomaly case detected prenatally, comprising of pancake kidney and jejunal atresia. A postnatal abdominal ultrasound confirmed both kidneys were fused in the midline at the aortic bifurcation level, along with a type 3b jejunal atresia. Based on the available limited evidence about pancake kidney, renal functions appear to remain largely preserved and unaffected as in our case according to 6 months of follow-up. However, further investigation is needed to explore any potential association with chromosomal and structural abnormalities in selected cases.

1. This trial investigated the effect on embryo injected with ochratoxin A (OTA) and the growth performance, jejunal morphology and barrier of ducklings to 21 d old.2. Two hundred forty, fertilised eggs were individually weighed and randomly assigned to two groups, a control (CON) and the OTA treatment, according to average egg weight. On d 13 of embryonic development, the treatment group was injected with 8 ng OTA/g egg and the CON group was injected with NaHCO3 solution as a placebo. All newly hatched ducklings were assigned to the CON or OTA group based on the different treatments. Each treatment consisted of six replicates and each included 10 ducklings and the experiment lasted until 21 d of age.3. The results showed that embryos injected with OTA affected the 21 d body weight (BW) and average daily gain (ADG) of ducklings (p < 0.05). OTA exposure increased the relative weights of the liver, pancreas, gizzard, proventriculus and jejunum (p < 0.05); and decreased the relative length of the jejunum of ducklings (p < 0.05). Moreover, jejunal crypt depth increased (p < 0.05) and the villus height-to-crypt depth ratio (Vh/Cd) decreased in the OTA-injected group (p < 0.05). Compared with those in the CON group, the mRNA expression of Zonula Occludens-1; (ZO-1) (p = 0.0582) and Occludin; (p = 0.0687) in the OTA treatment group was downregulated.4. The findings demonstrated that a single low-dose injection of OTA increased body weight and daily gain in ducklings. Moreover, embryo exposure to OTA had negative effects with increased relative weight of organs and the jejunal crypt depth, decreased relative length of the intestine and mRNA expression of tight junctions (ZO-1, Occludin).
RESUMO
PURPOSE: By selectively perfusing the first three jejunal arteries (JA), we aim to assess the individual perfusion length of small bowel (SB) and its impact on nodal resection in stage III-up small-intestinal neuroendocrine tumors (SI-NET). METHODS: Our anatomical research protocol implies a midline laparotomy and three measures of the SB length. We then perform a classical anterior approach of the superior mesenteric vessels. We carry on with the complete dissection and checking of the superior mesenteric artery (SMA) in order to identify the first three JA. Then we selectively perfuse each artery with colored latex solutions and measure the length of small bowel perfused respectively. RESULTS: We conducted our protocol on six cadaveric subjects. Mean(SD) SB length was 413(5.7), 535(13.2), 485(15), 353(25.1), 730(17.3) and 525(16° cm respectively from subject one to six. Most JA originated from the left side of the SMA. The first JA originated from its posterior wall in two subjects. Mean(SD) distance of origin of the first three JA was 4.6(1.3)cm, 6(1.1)cm and 7.1(0.9)cm respectively. Mean(SD) diameter of SMA was 10.8(3.3)mm. Mean diameter of the three first JA was 4(1.4)mm, 4(1.5)mm and 5(1.2)mm respectively. Mean(SD) SB length perfused by first and second JA was 224(14.9)cm, 175(8.6)cm, 238.3(7.6)cm, 84.3(5.1)cm, 233.3(5.8)cm and 218.3(10.4)cm respectively from subject one to six. CONCLUSION: We observed a trend suggesting that the first and second JA may sustain a SB length beyond the viable 1.5 m limit, implying the feasibility of stage III-up SI-NET resection with just two JA.

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.

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.

BACKGROUND: The early development of intestinal microbiota plays a fundamental role in host health and development. To investigate the difference in the intestinal microbial composition between Lantang and Landrace newborn piglets, we amplified and sequenced the V3-V4 region of 16 S rRNA gene in jejunal microbiota of Lantang and landrace newborn. RESULTS: The findings revealed that the dominant phyla in the jejunum of Lantang piglets were Firmicutes, Actinobacteria and Bacteroidetes, while the dominant phyla of Landrace is Proteobacteria and Fusobacteria. Specifically, Corynebacterium_1, Lactobacillus, Rothia, Granulicatella, Corynebacteriales_unclassified, Corynebacterium, Globicatella and Actinomycetales_unclassified were found to be the dominant genera of Lantang group, while Clostridium_sensu_stricto_1, Escherichia-Shigella, Actinobacillus and Bifidobacterium were the dominant genera of Landrace. Based on the functional prediction of bacteria, we found that bacterial communities from Lantang samples had a significantly greater abundance pathways of fatty acid synthesis, protein synthesis, DNA replication, recombination, repair and material transport across membranes, while the carrier protein of pathogenic bacteria was more abundant in Landrace samples. CONCLUSIONS: Overall, there was a tremendous difference in the early intestinal flora composition between Landang and Landrace piglets, which was related to the breed characteristics and may be one of the reasons affecting the growth characteristics. However, more further extensive studies should be included to reveal the underlying relationship between early intestinal flora composition in different breeds and pig growth characteristics.

A detailed knowledge of the surgical anatomy of tributaries of the superior mesenteric vein, especially proximal jejunal venous anatomy (first jejunal vein and jejunal trunk), is a key prerequisite for performing a safe pancreatico-duodenectomy. However, the available literature on the anatomical course and surgical relevance of these vessels is scarce, the nomenclature across the articles is heterogeneous, and the resulting evidence is confusing to interpret. Standardized terminology and an in-depth review of these vessels with regard to their course, termination, vascular relations, and variations will help the surgeons in planning and performing this complex surgery safely, especially when a venous resection and reconstruction is planned in cases of borderline resectable pancreatic cancer. A uniform nomenclature and a unifying classification are proposed in this review for these two tributaries to help resolve the literature conundrum. This standardized terminology and anatomical description will assist the radiologists in reporting pancreatic protocol-computed tomography scans and surgeons in selecting the appropriate steps for the different anatomical orientations of these tributaries for the performance of safe pancreatic surgery. This will also help future researchers communicate in well-defined terms in reference to these tributaries so as to avoid confusion in future studies.

PURPOSE: Pancreaticoduodenectomy (PD) for pancreatic cancer carries a high risk of massive intraoperative blood loss. The artery first approach (AFA) prevents blood loss during PD, but the optimal approach is unclear. The first jejunal vein (FJV) often comprises multiple veins and broadly supports venous drainage of the proximal jejunum. Its ligation carries a risk of proximal jejunum congestion. Here we investigated the anatomical characteristics of PD-associated vessels and AFA approach selection based on FJV anatomy. METHODS: This study included 148 Japanese living donors for liver transplantation. We reviewed their computed tomography images and assessed the anatomical pattern of PD-associated vessels in terms of FJV anatomy. RESULTS: The FJV traveled posterior to the superior mesenteric artery in 128 patients (86.5%, dorsal group) and anterior in 20 (13.5%, ventral group). The predominant draining vein of the inferior pancreaticoduodenal vein was the superior mesenteric vein in the ventral group (87.5%) and the FJV in the dorsal group (97.9%). Compared with the dorsal group, the ventral group had a significantly greater percentage with the superior mesenteric vein ventral to the superior mesenteric artery (30.0% versus 10.9%) and a significantly larger posterior superior pancreaticoduodenal vein diameter (3.2 ± 0.9 versus 2.7 ± 0.6 mm, p = 0.0029). These results were validated in patients with pancreatic head cancer. CONCLUSIONS: The anatomical characteristics of PD-associated vessels differed significantly between groups defined by FJV anatomy. Understanding the venous anatomy, especially the FJV, could support selection of the best approach in AFA for PD.

Hemorrhagic bowel syndrome (HBS) is a sporadic and fatal disease of predominantly lactating dairy cattle, characterized by segmental hemorrhage and luminal clot formation in the small intestine. Although, Clostridium perfringens and Aspergillus fumigatus have been associated with HBS, the pathogenesis and cause are currently unknown. In this study, 18 naturally occurring cases of HBS (7 necropsied immediately following euthanasia, 11 with 12-48 hour postmortem intervals) were investigated to characterize the pathology and the intestinal microbiome. Hemorrhagic bowel syndrome was characterized by a single small-intestinal, intramucosal hematoma with dissection of the lamina muscularis mucosae. In most cases necropsied immediately after euthanasia (4/7), the intestinal mucosa proximal to the hematoma contained 9 to 14, dispersed, solitary or clustered, erosions or lacerations measuring 4 to 45 mm. In 77% (37/48) of these mucosal lesions, microscopic splitting of the lamina muscularis mucosae comparable to the hematoma was present. These findings suggest the intramucosal hematoma to originate from small mucosal erosions through dissecting hemorrhage within the lamina muscularis mucosae. No invasive fungal growth was observed in any tissue. Bacteriological cultivation and nanopore sequencing showed a polymicrobial population at the hematoma and unaffected intestine, with mostly mild presence of C perfringens at selective culture. Gross and microscopic lesions, as well as the culture and sequencing results, were not in support of involvement of C perfringens or A fumigatus in the pathogenesis of HBS.

BACKGROUND: To compare the clinical efficacy of two alimentary tract reconstruction methods-"P"-shape jejunal interposition (PJI) and Roux-en-Y anastomosis after total gastrectomy. METHOD: The following search phrases were utilized to search PubMed, Cochrane Library, Embase, China Academic Journals Network Full-text Database (CNKI), and Wanfang Database as of April 2022: "gastrectomy," "Roux-en-Y," "interposition," "total gastrectomy," and "jejunal interposition." Meta-analysis of the operation time, intraoperative blood loss, complication rate, and postoperative nutritional status of patients was performed using RevMan 5.4 software. RESULTS: A total of 24 studies and 1887 patients were included in the study. Among patients who received a total gastrectomy, the operation time in the PJI group was substantially longer than that in the Roux-en-Y group (WMD = 19.77, 95% CI: 5.84-33.70, P = 0.005). The incidence of postoperative reflux esophagitis in the PJI group was considerably reduced than that in the Roux-en-Y group (OR = 0.39, 95% CI: 0.28-0.56, P < 0.01). The probability of postoperative dumping syndrome in the PJI group was significantly lower than that in the Roux-en-Y group (OR = 0.27, 95% CI: 0.17-0.43, P < 0.01), and the postoperative body mass changes were significantly lower in the PJI group than in the Roux-en-Y group (WMD = 3.94, 95% CI: 2.24-5.64, P < 0.01). The PJI group had substantially higher postoperative hemoglobin, albumin, and total protein levels than the Roux-en-Y group (WMD = 13.94, 95% CI: 7.77-19.20, P < 0.01; WMD = 3.97, 95% CI: 2.58-5.37, P < 0.01; WMD = 5.31, 95% CI: 3.45-7.16, P < 0.01). The prognostic nutritional index was higher in the PJI group than in the Roux-en-Y group (WMD = 9.25, 95% CI: 7.37-11.13, P < 0.01). CONCLUSION: PJI is a safe and effective reconstruction method and is superior to Roux-en-Y anastomosis in the prevention and treatment of postoperative complications and postoperative nutritional recovery in patients after total gastrectomy.

PURPOSE: Due to difficulties in breath holding, patients who undergo total laryngectomy may be prone to the development of chronic constipation. However, few reports have described chronic constipation in laryngectomized patients, and no report has described prevalence in patients who have undergone total pharyngolaryngectomy. METHODS: We conducted a cross-sectional study to investigate the prevalence of chronic constipation after laryngectomy and evaluated the relationship between patient characteristics and chronic constipation. Information on patient characteristics and the details of surgery were obtained from medical records and an original questionnaire survey in 50 patients. RESULTS: The prevalence of chronic constipation after laryngectomy was high, at 36%, with 18 cases. Patients who received total laryngectomy were significantly more likely to have chronic constipation than those who received total pharyngolaryngectomy (47.1% vs 12.5%, P = 0.026), who had a similar prevalence to the general public. Furthermore, the period from surgery to survey was significantly shorter in the constipation group than in the no constipation group (P = 0.043). CONCLUSIONS: The prevalence of chronic constipation in patients who had undergone laryngectomy for head and neck cancer was high, particularly in patients who received total laryngectomy and in those with only a short period since surgery.

INTRODUCTION: Free jejunal flap (FJF) reconstruction is a standard procedure for pharyngeal and cervical esophageal defects resulting from head and neck cancer resection. However, improvements in patients' quality of life after surgery require a further statistical approach. METHODS: An observational, retrospective, multivariate analysis was designed to report the incidence of postoperative complications and their association with clinical factors in 101 patients who underwent total pharyngo-laryngo-esophagectomy and FJF reconstruction for head and neck cancer at a university hospital between January 2007 and December 2020. RESULTS: Postoperative complications were observed in 69% of patients. In the reconstructive site, anastomotic leak, observed in 8% of patients was associated with vascular anastomosis in the external jugular vein system (age-adjusted odds ratio [OR]: 9.05, p = 0.044) and anastomotic stricture, observed in 11% of patients was associated with postoperative radiotherapy (age-adjusted OR: 12.60, p = 0.02). Cervical skin flap necrosis was the most common complication (34%) and was associated with vascular anastomosis on the right cervical side (age- and sex-adjusted OR: 4.00, p = 0.005). CONCLUSION: Although FJF reconstruction is a useful procedure, 69% of patients suffer a postoperative complication. We suppose that anastomotic leak is related to the low blood flow resistance of the FJF and inadequate drainage of the external jugular venous system, and anastomotic stricture is related to the vulnerability of the intestinal tissue to radiation. Furthermore, we hypothesized that the location of the vascular anastomosis may affect the mesenteric location of the FJF and the dead space in the neck, leading to the development of cervical skin flap necrosis. These data contribute to increasing our knowledge about postoperative complications related to FJF reconstruction.

Jejunal diverticula, like other intestinal diverticula, can become complicated and present as acute abdomen. Diagnosis is difficult and management in complicated cases can be surgical as well as conservative. We present two cases of complicated jejunal diverticulosis that presented with acute abdomen and were managed surgically. Post-operative recovery was satisfactory. Jejunal diverticula is a diagnostic challenge in a low-resource peripheral hospital.

Chyloperitoneum (CP) is a rare complication after bariatric surgery. We present a 37-year-old female with CP caused by a bowel volvulus following a gastric clipping with proximal jejunal bypass for morbid obesity. An abdominal CT image of a mesenteric swirl sign and abnormal triglyceride level of ascites fluid can confirm the diagnosis. In this patient, laparoscopy demonstrated dilated lymphatic ducts caused by a bowel volvulus resulting in the exudation of chylous fluid into the peritoneal cavity. After the reduction of bowel volvulus, she made an uneventful recovery with complete resolution of the chylous ascites. The presence of CP could indicate a situation of small bowel obstruction in patients with a history of bariatric surgery.
