Atresia pilórica / Pyloric Atresia

Introducción: La atresia pilórica es una afección rara, que en el 40-50 por ciento de los casos se asocia a otras anomalías, frecuentemente con la epidermolisis bullosa, asociación conocida como síndrome de Carmi. Objetivo: Informar sobre la evolución de una paciente tratada por atresia pilórica que tenía además una epidermolisis bullosa. Presentación del caso: Recién nacida con antecedentes prenatales de polihidramnios, parto eutócico a las 30,4 semanas, sepsis ovular materna, peso al nacer 1430 gramos; múltiples lesiones en piel, ampollosas y aplasia cutis en pierna izquierda. Se ventiló desde sala de partos, La paciente no toleró la alimentación enteral mínima. Se realizó estudio radiográfico y no se visualizó paso de contraste al píloro. Se diagnosticó una atresia pilórica y se operó al cuarto día de nacida. La paciente tenía una atresia pilórica tipo 2: sustitución del tejido pilórico por tejido fibroso. Se hizo una gastroduodenostomía. En su evolución se incrementaron por día las lesiones en piel, y tuvo reapertura del ductus arterioso, trastornos hidroelectrolíticos, y hemidinámicos que provocaron el fallecimiento a los 14 días de nacida. Conclusiones: La atresia pilórica es una afección muy rara, que debe tenerse en cuenta en recién nacidos con epidermolisis bullosa por la frecuente asociación entre estas dos afecciones; además, cuando existen antecedentes de polihidramnios y no tolerancia a la alimentación enteral. Los pacientes con la asociación atresia pilórica y epidermolisis bullosa generalmente presentan una evolución desfavorable(AU)

Introduction: Pyloric atresia is a rare condition, which in 40-50 percent of cases is associated with other anomalies, often with epidermolysis bullosa, an association known as Carmi syndrome. Objective: To report on the evolution of a patient treated due to pyloric atresia who also had epidermolysis bullosa. Case presentation: Female newborn with prenatal history of polyhydramnios, eutocic delivery at 30.4 weeks, maternal ovular sepsis, birth weight 1430 grams, with multiple skin lesions, blisters and aplasia cutis in the left leg. She was ventilated from the delivery room. The patient did not tolerate minimal enteral feeding. A radiographic study was performed and no contrast passage to the pylorus was visualized. Pyloric atresia was diagnosed and operated on the fourth day of birth. The patient had pyloric atresia type 2: replacement of pyloric tissue by fibrous tissue. A gastroduodenostomy was done. In its evolution, skin lesions increased per day and reopening of the ductus arteriosus was performed, she had hydroelectrolyte disorders, and hemidynamic disorders that caused death at 14 days of birth. Conclusions: Pyloric atresia is a very rare condition, which should be taken into account in newborns with epidermolysis bullosa due to the frequent association between these two conditions, also when there is a history of polyhydramnios and no tolerance to enteral feeding. Patients with pyloric atresia and epidermolysis bullosa usually have an unfavorable outcome(AU)

Vitamin A retinopathy secondary to Billroth II anastomosis triggered after the beginning of dialysis.

PURPOSE: To report a case of vitamin A retinopathy secondary to Billroth II anastomosis triggered after the beginning of dialysis in a patient with a chronic renal failure. CASE REPORT: A 73-year-old male complained of nyctalopia that had started 9 months ago, coinciding with the beginning of dialysis. His medical history is remarkable for hepatic cirrhosis and Billroth II anastomosis 20 years ago. Best-corrected visual acuity (BCVA) was 60 letters in both eyes. Dilated fundus examination showed faint white-yellowish dots. Optical coherence tomography (OCT) illustrated hyperreflective dots and small hyporreflective cavities between the retinal pigment epithelium (RPE) and the ellipsoid zone (EZ). En face OCT showed multiple hyperreflective dots that coincide with white-yellowish dots of the fundus, and multiple hyporreflective defects which correspond to hyporreflective cavities seen in the OCT. Visual field examination showed concentric narrowing of the visual field. A diagnosis of vitamin A deficiency was confirmed and oral vitamin A supplementation was initiated. One month after treatment, the patient reported a subjective improvement of nyctalopia, and BCVA ameliorated up to 80 and 85 letters. Fundus examination, OCT, and en face OCT showed a diminution of the observed lesions. Moreover, visual field improved. CONCLUSION: Early diagnosis of vitamin A deficiency can prevent irreversible visual sequelae. This highlights the crucial role of ophthalmologists in the prompt detection of this condition. A lifelong monitoring should be needed in patients undergoing biliopancreatic diversion surgery. Furthermore, OCT and en face OCT becomes a main tool in the diagnosis and monitor response to treatment.

[A Case of Gastric Cancer Which Caused Severe Anemia(Hemoglobin 1.8 g/dL)].

A 61-year-old woman, who consulted another doctor with chief complaints of epigastric pain, nausea, anorexia, palpitation, and shortness of breath since a month was referred to our hospital for diagnosis and treatment. She was diagnosed with advanced gastric cancer. She was also found to have severe anemia(hemoglobin 1.8 g/dL)and malnutrition. With adequate precautions to prevent development of heart failure and refeeding syndrome, the patient was treated for anemia with blood transfusion and intravenous iron injection; and for malnutrition with intravenous hyperalimentation and enteral nutrition. The patient underwent distal gastrectomy 17 days after admission. Histological examination revealed a type 3 moderately differentiated tubular adenocarcinoma>solid type of poorly differentiated adenocarcinoma>mucinous adenocarcinoma corresponding to pT4a, pN3a, pStage ⅢB, respectively. The postoperative course was good and adjuvant chemotherapy was started 22 days after surgery. However, the patient died approximately 15 months after surgery due to metastases of gastric cancer to the lymph nodes.

Clinical assessment and management of severe acute pancreatitis: a multi-disciplinary approach in the XXI century.

Acute pancreatitis (AP) is the most common gastrointestinal disorder requiring hospitalization, with a high rate of morbidity and mortality. Severe AP is characterized by the presence of persistent organ failure involving single or multiple organs. Clinical evolution, laboratory and radiological assessment are necessary to evaluate the prognosis and inform the management of AP. The onset of severe AP may be classified in two principal phases. The early phase, during the first week, is characterized by the activation of the auto-inflammatory cascade, gut dysbiosis, bacterial translocation, and the down-regulation of immune responses. The late phase is characterized by the development of local and systemic complications. Several old paradigms have been amended in the management of AP patients, such as the indication of nutrition, the use of antibiotic therapy, pain control strategies, and even the use of surgery. Real world evidence has shown that in the majority of cases a step-up approach is most effective. In this review, we discuss the clinical assessment and improvements to the management of patients with severe AP in a high volume center where a multi-disciplinary approach is performed.

Effectiveness of laparoscopic stomach-partitioning gastrojejunostomy for patients with gastric outlet obstruction caused by advanced gastric cancer.

BACKGROUND: Distal advanced gastric cancer (AGC) occasionally causes gastric outlet obstruction (GOO). We developed a laparoscopic stomach-partitioning gastrojejunostomy (LSPGJ) to restore the ability of food intake. METHODS: This was a retrospective study performed at a single institution. Of consecutive 78 patients with GOO caused by AGC between 2006 and 2012, 43 patients who underwent LSPGJ were enrolled. The procedure was performed in an antiperistaltic Billroth II fashion, and the afferent loop was elevated and fixed along the staple line of the proximal partitioned stomach. Then, patients for whom R0 resection was planned received chemotherapy prior to laparoscopic gastrectomy. The primary end point was food intake at the time of discharge, which was evaluated using the GOO scoring system (GOOSS). Short- and long-term outcomes were assessed as secondary end points. Overall survival was estimated and compared between the groups who received neoadjuvant chemotherapy followed by surgery (NAC group), definitive chemotherapy followed by curative resection (Conversion group), and best supportive care (BSC group). RESULTS: The median operative time was 92 min, blood loss did not exceed 30 g in any patient, and postoperative complications (Clavien-Dindo grade ≥2) were only seen in four patients (9.3 %). The median time to food intake was 3 days, and GOOSS scores were significantly improved in 41 patients (95.3 %). Chemotherapy was administered to 38 patients (88.4 %), of whom 11 later underwent radical resection, and 4 of 11 patients underwent conversion surgery following definitive chemotherapy. Median survival times were significantly superior in the NAC (n = 7; 46.8 months) and Conversion (n = 4; 35.9 months) groups than in the BSC group (n = 26; 12.2 months); however, the difference was not significant between the Conversion and NAC groups. CONCLUSIONS: LSPGJ is a feasible and safe minimally invasive induction surgery for patients with GOO from surgical and oncological perspectives.

A case of gastrojejunocolic fistula with steatohepatitis.

A man in his 30s, who had undergone retrocolic Billroth II reconstruction for perforated duodenal ulcer, presented with watery diarrhea for 2 years and suspected fatty liver. He was referred to our hospital for management of chronic diarrhea, weight loss, hepatopathy and hypoalbuminemia. Initial upper and lower gastrointestinal endoscopies were negative. Since a small bowel lesion was suspected, peroral single-balloon enteroscopy was performed, which identified feces-like residue near the Billroth II anastomotic site and a connection to the colon separate from the afferent and efferent loops. Transanal single-balloon enteroscopy identified a fistula between the gastrojejunal anastomosis and transverse colon, with the scope reaching the stomach transanally. Barium enema confirmed flow of contrast medium from the transverse colon through the fistula to the anastomotic site, allowing the diagnosis of gastrojejunocolic fistula. Liver biopsy showed relatively severe steatohepatitis (Brunt's classification: stage 2-3, grade 3). Resection of the anastomotic site and partial transverse colectomy were performed to remove the fistula, followed by Roux-en-Y reconstruction. Postoperatively, watery diarrhea resolved and the stools became normal. Hepatopathy and hypoproteinemia improved. One year later, liver biopsy showed marked improvement of steatosis. This case demonstrated marked improvement of both diarrhea/nutritional status and steatohepatitis after treatment of gastrojejunocolic fistula, suggesting that the fistula caused non-alcoholic steatohepatitis.

Gastric remnant cancer patients had a better prognosis than upper-third gastric cancer patients in a case-control study after surgical treatment.

BACKGROUND: The aim was to compare the clinicopathological features and prognostic outcomes of gastric remnant carcinoma patients with those of patients with upper-third gastric cancer. METHODS: Clinical data extracted from 112 gastric remnant carcinomas and 367 upper-third gastric cancer patients were analyzed to explore the clinicopathologic differences between two groups. After radical resection, prognostic difference between them was evaluated through a 1:2 matched case-control study. RESULTS: The pattern of gastric remnant carcinomas showed a male predominance. Undifferentiated type histology, depth at T4 stage and distant metastases were more frequent in gastric remnant carcinomas than in upper-third gastric cancers (P <0.05). The radical resectability of gastric remnant carcinomas was lower and the multi-visceral resectabilitiy was relatively higher than the other group (P = 0.00). Gastric remnant carcinomas trended to have a higher incidence of metastases to either mesojejunum or lower mediastinal lymph nodes than upper-third gastric cancers, but patient survival was not significantly different. In the case-control study, gastric remnant carcinomas had a better prognosis than upper-third gastric cancers after radical resection when the clinicopathologic features and surgical treatment were matched. CONCLUSIONS: Although there was no significant prognostic distinction between gastric remnant carcinomas and upper-third gastric cancer, after radical surgical treatment, patients with the former had an even better prognosis.

Safe temperature range for intraoperative and early postoperative continuous hyperthermic intraperitoneal perfusion in a swine model of experimental distal gastrectomy with Billroth II reconstruction.

BACKGROUND: The current study sought to investigate the safety of intraoperative and early postoperative continuous hyperthermic intraperitoneal perfusion (IEPCHIP) at different temperatures in a swine model of experimental distal gastrectomy with Billroth II reconstruction. METHODS: Thirty pigs were randomly divided into 5 groups. Two groups were used as the control groups (groups A1 and A2), and 3 groups were used as the perfusion groups (groups B, C and D). Pigs in group A1 received distal gastrectomy with Billroth II reconstruction only. Pigs in groups A2, B, C and D received the same surgery as group A1, followed by IEPCHIP at 37 ± 0.5°C, 42.5 ± 0.5°C, 43.5 ± 0.5°C or 44.5 ± 0.5°C, respectively. The perfusion time was assessed for each pig in group A2 as well as in the perfusion groups, and the perfusions were performed twice for each group. The first perfusion was conducted intraoperatively, and the second perfusion was initiated 1 day after surgery. Data concerning vital signs and hepatic and renal function were collected. Parameters concerning anastomotic healing, the pathology of the anastomotic tissue and abdominal adhesion were compared. RESULTS: The vital signs and hepatic and renal functions of the pigs in groups A1, A2, B and C were not significantly affected by this procedure. In contrast, the vital signs and hepatic and renal functions of the pigs in group D were significantly affected. Compared to the pigs in groups A1, A2 or B, the anastomotic bursting pressure, breaking strength and hydroxyproline content in group C and D pigs were significantly lower. No significant differences were observed in these parameters between groups A1, A2 and B. Abdominal adhesion was more severe in group D pigs. Collagen deposition in group A1, A2 and B pigs was dense in the anastomosis, and inflammatory cell infiltration was observed in group D. CONCLUSIONS: IEPCHIP at 42.5 ± 0.5°C was safe and caused minimal impairments. However, anastomotic healing was affected by perfusion at 43.5 ± 0.5°C and 44.5 ± 0.5°C, and abdominal adhesion was most severe in the group D animals, which were perfused at 44.5 ± 0.5°C.

[Gastrojejunocolic fistula--a rare complication of stomach surgery]. / Fistula gastrojejunocolica--complicatie rara a chirurgiei stomacului.

The gastrojejunocolic fistula represents a clinical entity that occurs very rarely following gastro-jejunal anastomoses and manifests itself clinically and paraclinically by a severe malabsorption syndrome. The results of the physiopathological approach may be summed up as follows: reduced level of seric proteins, fluid and electrolytic depletion, deficiencies in the absorption of the vitamins soluble in fats and water, which may all vary from mildness to severeness, depending on the flow rate of the fistula. Most often, the diagnosis is set by performing barium enema, which is positive for all cases, whereas the barium passage is less efficient, enabling diagnosis in only 33% of the cases. The radiological image may be reduced on principle to one single sign: the abnormal fistulous trajectory (barium passes from the stomach directly into the colon or the enema fills the gastric lumen). It is recommended that surgical treatment be performed in a single stage, by resecting the entire fistula and re-establishing the gastro-jejunal and colic continuity. We report a case of gastrojejunocolic fistula in a patient that underwent 2/3 gastric resection for gastric ulcer 9 years ago.

Acquired copper deficiency following prolonged jejunostomy feeds.

A 19-year-old man who developed extensive oesophageal lye (Alkali) stricture and received long-term enteral nutrition (eight months) with a jejunostomy tube developed macrocytic anaemia (Hb: 41 g/L) with leucopenia (white blood cell [WBC]: 3.0 x 10(9)/L). The patient's serum vitamin B12, folate, iron and liver function tests were normal. Bone marrow examination revealed gross erythroid hyperplasia and cytoplasmic vacuolization of erythroid and myeloid elements. Further investigations revealed low serum copper (0.3 micromol/L) and ceruloplasmin concentrations (<30 mg/L) with marginally low normal serum concentration of red cell peroxidase (13 U/gHb), establishing the diagnosis of copper deficiency anaemia. The anaemia and leucopenia responded intermittently to intravenous copper therapy, but the serum copper concentration dropped when intravenous copper therapy was withdrawn. Enteral jejunostomy copper supplementation failed to maintain adequate serum copper concentrations. After stabilizing the general condition of the patient, a pharyngo-gastric anastamosis was performed and normal oral diet commenced, which restored normal serum copper concentration. This case report suggests that copper supplements in the form of copper sulphate are not adequately absorbed when administered through a jejunostomy tube.

A Case of Gastrojejunocolic Fistula as a Complication after Gastrojejunostomy / 대한소화기내시경학회지

Gastrocolic and gastrojejunocolic fistula are well-recongnized but rare complications of a variety of diseases, and surgical or endoscopic procedures We had a case of gastrojejunocolic fistulae associated with marginal ulcer following gastrectomy with Billroth II gastrojejunostomy for recurrent peptic ulcer disease. He had chronic watery diarrhea, weight loss and fecal eructation and gastrojejunocolic fistula was dignosed by gastroscopy, barium enema, upper gastrointestinal series and abdominal CT scan. He underwent subtotal gastrectomy with Roux-en-Y gastrojejunal anastomosis and en-bloc resection including the fistula and surrounding colon, jejunum and gastric segments. Hereafter, he showed disappearance of diarrhea, along with slow rate of weight gain.

[Clinico-morphological assessment of early and late results of laser therapy of the anastomosis area after radical surgeries for stomach cancer]. / Kliniko-morfologicheskaia otsenka blizhaishikh i otdalennykh rezul'tatov lazernoi terapii zony anastomoza posle radikal'nykh operatsii po povody raka zheludka.

The study included 52 patients after gastrectomy for carcinoma of the proximal part of the stomach. Endoscopic laser therapy was made in 32 patients to reduce inflammation in the anastomosis zone 2-3 weeks after surgery. Drug therapy was made in 20 patients within the same time period. Histochemical study of the biopsy material of esophageal and intestinal part of the anastomosis was carried out. It is revealed that application of copper vapor laser early after surgery reduces edema and inflammation in the anastomosis zone for 2 weeks as well as accelerates the growth of granulation tissue forming a delicate scar thus preventing formation of scar stenosis.

Nutrición y SIDA / Nutrition and AIDS

La infección por el VIH en la infancia es un importante problema sanitario. Se calcula que cada año nacen 400-600 hijos de madres seropositivas.El diagnóstico precoz de la infección por el VIH en el niño, es de gran importancia para instaurar lo antes posible tratamiento antirretroviral, profilaxis de infecciones oportunistas, inmunización activa y pasiva, así como un soporte psicosocial y nutricional adecuado.Estos niños presentan una disregulación en el metabolismo de las citocinas que parecen jugar un importante papel en la malnutrición, la cual es de etiología multifactorial y puede presentarse en cualquier momento evolutivo de la enfermedad.Sería importante determinar los índices nutricionales con mayor poder discriminativo para valorar la malnutrición; pues se ha encontrado una correlación entre el deterioro de la situación clínica, inmunológica y nutricional.Las nuevas estrategias terapéuticas de la desnutrición en niños con infección por VIH, se basan en la administración de acetato de megestrol y hormona de crecimiento cuyo efecto parece ser beneficioso (AU)

[Diagnosis, prevention and treatment of postoperative reflux gastritis]. / Diagnostika, profilaktika i lechenie posleoperatsionnogo refliuks-gastrita.

Postoperative reflux gastritis in persons who were operated on for peptic ulcer occurs much more frequently after resection of the stomach (68.6%) than after organ-preserving operations on the stomach (39.4%). The incidence of reflux gastritis after gastric resection depends on the type of gastroenteroanastomosis. It is encountered much less frequently after Roux' operation (9.2%). The pronounced character and frequency of reflux gastritis after organ-preserving operations on the stomach are determined by the type of stomach-draining operations, the localization of the ulcer before the operation, whether in the stomach or the duodenum, the existence of duodenogastric reflux (DGR) before the operation. Measures for the prevention of postoperative reflux gastritis in the management of peptic ulcer are as follows: (a) wide introduction of organ-preserving operations, preferably SPV by itself or in combination with duodenoplasty; (b) formation of Roux' gastroenteroanastomosis when resection of the stomach is indicated. Reflux gastritis must be treated by nonoperative methods, including medicinal, dietetic, and spa therapy. Surgery is indicated in reflux gastritis combined with other diseases of a stomach which had been operated on, for which an operation is necessary, and in occasional cases of erosive reflux gastritis.

[Gastrojejunocolic fistula. Report of 5 cases].

Gastrojejunocolic fistula is rare complication of recurrent peptic ulcer disease after gastrectomy and gastrojejunostomy. This paper reported five cases of gastrojejunocolic fistula. It's etiological, clinical, and surgical features were briefly discussed. The symptoms of gastrojejunocolic fistula are diarrhea, upper abdominal pain, gastrointestinal bleeding, fecal vomiting, anasarca, and weight loss. The physical examinations and laboratory studies revealed malnutrition. The diagnosis is most reliably and frequently made by barium enema and gastroscopy. Surgical treatment of gastrojejunocolic fistula includes one-stage resection, complete remove of antral mucosa; vagotomy; partial re-resection of the gastric stump; excision of the fistulous connection with the colon. TPN or TEN should be administered in patients suffering from malnutrition with TEN as the first choice in those when a nasoenteric tube could placed into the jejunum.

[Enteral nutrition in the pre- and postoperative therapy of gastric neoplasms. Comments on 21 cases]. / La nutrizione enterale nella terapia pre-postoperatoria delle neoplasie gastriche. Considerazioni su 21 casi.

Results of personal experience of the application of enteral nutrition in a group of patients (21) submitted to surgery for gastric cancer are reported. Enteral nutrition proved easy to perform, provided a significant improvement in some of the parameters considered in the study, was without significant complications and presented acceptable management costs.

Electrical pacing of the Roux limb resolves delayed gastric emptying.

This study compares antegrade gastric and Roux-limb electrical pacing in the evaluation and treatment of delayed gastric emptying following vagotomy, antrectomy and Roux-Y enterostomy. Twenty-four male Sprague-Dawley rats (250 g) underwent midline laparotomy, truncal vagotomy, antrectomy, and Roux-Y jejunostomy. Pacemaker leads were implanted 1 cm apart in both the gastric fundus and proximal Roux limb. Pacing was accomplished using a 0.5 mA, 50 msec, 0.33 Hz signal and monitored by an oscilloscope. Animals were fasted for 2 hr and then gavaged with 1.0 cc of 99mTc-labeled egg white. At 1 hr rats were anesthetized. The stomach, Roux limb, small intestine, and colon were doubly ligated and excised without disturbing their contents. The total number of counts per minute per rat was determined in a gamma radiation counter, and percentage gastric emptying (GE) was evaluated. Group I controls (n = 8) retained 76 +/- 15.8% for a GE of 24%. Group II gastric paced rats (n = 8) retained 64.5 +/- 19.2% (GE 35.5%) and Group III Roux-limb paced rats (n = 8) retained 46.8% +/- 13.2 (GE 53.2%) (P less than 0.005 III vs I, P less than 0.05 III vs II). The amount of radioactive meal distal to the Roux limb was also evaluated. Group I had 15.7 +/- 16.1%, Group II (gastric paced) 20.5 +/- 19.0%, and Group III (Roux-limb paced) 37.2 +/- 11.9% (P less than 0.005 III vs I, P less than 0.05 III vs II). These data imply that Roux-en-Y limb dysmotility may contribute to delayed gastric emptying following vagotomy, antrectomy, and Roux-Y enterostomy.(ABSTRACT TRUNCATED AT 250 WORDS)

[Organ-sparing operations in pyloroduodenal stenosis caused by peptic ulcer]. / Organosokhraniaiushchie operatsii pri piloroduodenal'nom iazvennom stenoze.

An experience with the treatment of 106 patients with pyloroduodenal stenosis of ulcerous etiology by vagotomy with draining operations has shown high efficiency of these measures resulting in lower rate of postoperative lethality. Selective proximal and stem vagotomy does not aggravate gastric atony in patients with stenosis. Electro-stimulation was found to be an effective method of treatment of this complication in the postoperative period of patients with gastric atony.
