Background: Diabetic hand syndrome is a complication of diabetes mellitus that is rarely described in Mexico. It covers a wide spectrum of nervous, tendinous and infectious disorders. The tropical variant of the disease is described as a necrotizing infection in the upper extremity, generally secondary to superficial trauma. Treatment includes metabolic control, antibiotics and different surgical techniques. Currently, complementary therapies include surgical debridement, flap reconstruction, negative pressure therapy, larval debridement, and stem cell grafting. The objective was to describe negative pressure therapy (NPT) as an adjunctive treatment for a case of tropical diabetic hand syndrome (TDHS) complicated by abscess and compartment syndrome, and we also made a literature review., Clinical Case: 50-year-old male patient with diabetic hand syndrome complicated by abscess and compartment syndrome. Fasciotomy and surgical drainage were performed, complementing the treatment with negative pressure therapy. After 10 days of complementary therapy and 20 more days of follow-up, the patient presented adequate remission., Conclusion: The use of NPT in the treatment of TDHS helped to limit the infection damage, and allowed the patient to be monitored on an outpatient basis, reducing his hospital stay., (Licencia CC 4.0 (BY-NC-ND) © 2024 Revista Médica del Instituto Mexicano del Seguro Social.)

Background: Splenic infarction is a rare cause of acute abdomen. The two main causes are thromboembolic diseases and infiltrative hematological disorders. The splenic abscess is the result of a hematogenous seeding, whose causes are trauma, splenic artery embolization, endocarditis, and immunocompromised states., Clinical Case: 48-year-old male patient with a history of chronic myelomonocytic leukemia on mercaptopurine-based treatment, who presented intermittent asthenia, adynamia, and abdominal distension for 2 months; a computed tomography of the abdomen with intravenous contrast was performed, reporting areas of infarction and an image suggestive of a splenic abscess in the upper pole, for which an open splenectomy was performed with adequate clinical evolution. A documentary review of the disease and of the therapeutic options was carried out, with an emphasis on surgical management., Conclusion: The main cause of morbidity and mortality in the case presented was splenic infarction, which is aggravated by the presence of hematological diseases; therefore, the identification of those patients at risk of complications will allow in a timely manner a diagnostic and therapeutic approach, and the detection of those who require urgent surgical management., (Licencia CC 4.0 (BY-NC-ND) © 2024 Revista Médica del Instituto Mexicano del Seguro Social.)

Background: Hemophagocytic syndrome or hemophagocytic lymphohistiocytosis (HL) is an immune hyperactivation of multifactorial etiology, characterized by excessive activation of lymphocytes and macrophages, as well as numerous pro-inflammatory cytokines. It has a non-specific and highly variable clinical presentation, with splenomegaly being one of the clinical manifestations. Due to its nature, it can manifest during childhood or adult life, which is why it is a disease of diagnostic and therapeutic complexity., Clinical Case: 38-year-old male patient without comorbidities, who presented with abdominal pain, choluria, fever > 38 °C and diaphoresis of more than 10 days of evolution. A bone marrow aspirate was performed as part of the diagnostic approach with data compatible with hemophagocytosis and cytopenias. The immunosuppressive management did not show the expected response, which is why an open splenectomy was performed as the last therapeutic option with adequate hematological control. A documentary review of the disease was carried out, and of the therapeutic options, emphasizing surgical management in case of refractoriness to medical treatment., Conclusions: Splenectomy increases the overall survival rate and the time free of HL progression, even though there are still no studies to determine with certainty the ideal time to perform a splenectomy in patients with pancytopenia without splenomegaly who suffer from hemophagocytic syndrome., (Licencia CC 4.0 (BY-NC-ND) © 2024 Revista Médica del Instituto Mexicano del Seguro Social.)

Background: Several guidelines have put forward recommendations about the perioperative process of cholecystectomy. Despite the recommendations, controversy remains concerning several topics, especially in low- and middle-income countries. The aim of this study was to develop uniform recommendations for perioperative practices in cholecystectomy in Mexico to standardize this process and save public health system resources., Methods: A modified Delphi method was used. An expert panel of 23 surgeons anonymously completed two rounds of responses to a 29-item questionnaire with 110 possible answers. The consensus was assessed using the percentage of responders agreeing on each question., Results: From the 29 questions, the study generated 27 recommendations based on 20 (69.0%) questions reaching consensus, one that was considered uncertain (3.4%), and six (20.7%) items that remained open questions. In two (6.9%) cases, no consensus was reached, and no recommendation could be made., Conclusions: This study provides recommendations for the perioperative management of cholecystectomy in public hospitals in Mexico. As a guide for public institutions in low- and middle-income countries, the study identifies recommendations for perioperative tests and evaluations, perioperative decision making, postoperative interventions and institutional investment, that might ensure the safe practice of cholecystectomy and contribute to conserving resources., (Copyright © 2020 International Hepato-Pancreato-Biliary Association Inc.

We present the unique case of a young female woman with an infected left liver hematoma as a complication of a previous endoscopic retrograde cholangiopancreatography for a choledocolithiasis. Urgent liver resections are rarely indicated and are usually performed in cases of important liver trauma. To our knowledge this is the first case of an urgent liver resection for the rare indication of late hepatic infected hematoma after an ERCP.

Hepatic mucinous cystic neoplasms represent a challenging pathology due to their very low frequency, insidious presentation and unclear demography due to the limited cases reported to date. Surgical treatment is mandatory when possible to prevent recurrence and malignant transformation. The case presented herein has a peculiarity, mainly an increased level of CA 19-9 which has not been previously reported.

We present the very unusual case of a 38-year-old woman with acute appendicitis and intestinal obstruction. During surgery, a 2.5 cm gallstone impacted at the base of the cecal appendix was found as the cause of a gangrenous appendicitis and obstruction; a choledochal-duodenal fistula was found during the same surgery with no gallstones remaining in the gallbladder or elsewhere. The case was managed by appendectomy with retrieval of the gallstones and no other procedure was performed for the gallbladder or the fistula, since no other gallstone was found on examination. Previously, she was found to have a round, radio-opaque image on the right iliac fossa on imaging, initially identified as an appendicolith, but after pathological examination it turned out to contain cholesterol and calcium bilirubinate. Gallstone ileus as the cause of an obstructive gangrenous appendicitis is a very unusual disease presentation that should be kept in mind when finding an unusual appendicolith presentation in or out the appendix.

Foreign bodies are a common problem in the daily endoscopic practice. Nevertheless, long objects as toothbrushes, sometimes pose a special problem when trying to remove them from the stomach, due to the difficulty of passing through the hiatus. Endoscopic retrieval of toothbrushes has seldom be reported.

The thyroid descends through the foramen cecum leaving the thyroglossal duct, which disappears between the fifth and the tenth week of pregnancy. The lack of involution of any part of this duct results in thyroglossal cyst formation. Its diagnostic approach is made by cervical ultrasound, computed tomography and magnetic resonance imaging. Approximately 1 % of the thyroglossal cyst formation contains malignant elements, and the most reported primary tumor has been papillary carcinoma. The recommended treatment for these carcinomas is controversial and it has evolved as time goes by. From Sistrunk procedure to neck dissection with total thyroidectomy and complementary therapies, such as iodine ablation and thyroid supplements, yet there is still no consensus as to the type of surgery and postoperative management it should be used to treat this carcinoma. Therapy should be applied according to each specific case, and it should be based on histological diagnosis, the invasive character of the tumor, and the lymph node affectation. In this paper we review the literature published so far with regards to the treatment of this carcinoma.

Laparoscopic Y Roux gastric bypass (YRGB) is the most performed bariatric surgery. There are 3 main techniques in the construction of the gastrojejunostomosis (GJA). The size of the GJA and its relation to the reduction of excess weight has been previously debated. The aim of our study was to determine whether the GJA area in YRGB correlates with the loss of excess weight at 1 year postoperatively. Patients who complied 1 year after YRGB underwent an upper gastrointestinal endoscopy. Images of the GJA were obtained and the area of the GJA was calculated. A statistical analysis, adjusting for age and body mass index preoperatively obtained an r of -0474 and P=0.032, demonstrating a significant negative correlation between the GJA area and the percentage of excess weight loss. A statistically significant negative correlation between the GJA area and the percentage of the excess weight loss was shown. The number of patients evaluated should be increased for a higher statistical significance to corroborate whether the stoma size influences the loss of weight in YRGB patients.

Background: Vaginal evisceration is a rare event associated to be associated with several factors. In premenopausal women it is often associated with trauma during intercourse, rape, iatrogenic injury and introduction of foreign objects. In postmenopausal women 73% of cases are associated with previous vaginal surgery or hysterectomy., Case Report: Here we present the case of a female patient who had a vaginal evisceration six days after an abdominal hysterectomy. The patient underwent an abdominal reduction of the small bowel, but due to irreversible vascular compromise it was resected. The vaginal cuff was closed with interrupted non-absorbable sutures., Conclusion: Vaginal evisceration is a rare disease associated with pelvic surgery. When it happens, it should be addressed as an emergency. The abdominal approach is the choice when there is trauma or intestinal ischemia, while the combined vaginal with laparoscopic approach is a good option in selected patients.

Background: adenocarcinoid tumor is a rare malignancy that combines clinical and histological features of epithelial origin (adenocarcinoma) and neuroendocrine (carcinoid), occupies less than 1 % of all colorectal cancer histology, occurring mainly in the appendix and its presence in the colon is rare., Clinical Case: we present a case of a 41-year-old female with sigmoid colon tumor, who underwent an extended left hemicolectomy and anastomosis; having a good postoperative evolution, with hospital stay of seventh days. The final histopathological study reported was adenocarcinoid colon tumor with free margins of injuries and four positive nodes of adenocarcinoma., Conclusions: adenocarcinoid tumors are present in the appendix in 85 to 95 % of all cases and only 6 % are located in the colon (13 % in sigmoid). Early diagnosis is certainly the most important determinant of good prognosis, in these cases the five-year survival is 80 to 84 %, and 15 years of 60 %.

Introduction: The gallbladder and bile ducts originate through a complex process during the 4th gestational week; there is a wide variety in their anatomy., Objective: To identify the type, frequency, and association with certain pathologies of anatomic variations of bile ducts in patients in which endoscopic retrograde colangiography (ERC) was performed., Methods: Six hundred and six patients in whom ERCs were performed from 2005 to 2007 in the Endoscopio Unit at the Hospital General Dr. Manuel Gea González in Mexico City were included. Variations in bile duct anatomy seen in the X-ray taken during ERC were identified. Demographic characteristics of the patients, indications of the study, complications, treatments, and type of anatomic variant were registered. Descriptive statistics were used to analyze the information. X2 and Fisher´s exact test were also performed for the comparison between patients with and without anatomic variations., Results: We identified biliary anatomic variations in 5.1% of patients in the study. Among them, seventy- seven per cent were women, with a mean age of 41 years. The anatomic variation most frequently found was a low union of the cystic duct with the common hepatic duct. The main diagnosis during ERC was choledocholithiasis in 71% of patients. Bile duct injuries were found in only 3.2% of patients with anatomic variations., Conclusions: Anatomic variations in bile ducts identified by ERC are frequent in Mexican population; nevertheless they were not associated with the occurrence of bile duct injuries.

Background: 99mTc sestamibi scanning and aspiration biopsy can predict the histopathological result of a thyroid nodule fairly accurately., Objective: To determine the accuracy of 99mTc sestamibi scanning in detecting malignancy in patients with thyroid nodule confirmed by definitive histopathological report after thyroidectomy., Material and Methods: A total of 69 patients with a solitary thyroid nodule were studied. In all patients, fine needle aspiration, total thyroidectomy for suspected thyroid cancer, and histological analysis of the surgical specimen were performed. There were 54 patients with a positive 99mTc sestamibi scan; of these, malignancy was confirmed by histological analysis in 25 and excluded in 29. There were 15 patients with a negative 99mTc sestamibi scan; of these, three had a final diagnosis of cancer and 12 were confirmed as cancer-free., Results: The diagnostic accuracy of 99mTc sestamibi scanning in detecting malignancy in thyroid nodules was determined through a statistical analysis. 99mTc sestamibi scan for thyroid cancer had a sensitivity of 89.28% and a specificity of 29.25%. The positive predictive value was 46.29% and the negative predictive value was 80%., Conclusions: We believe that 99mTc sestamibi scan should be routinely used in all patients with a thyroid nodule and an indeterminate result on fine needle aspiration. This procedure is most useful in excluding malignancy in patients with a negative 99mTc sestamibi scan., (Copyright © 2010 SEEN. Published by Elsevier Espana. All rights reserved.)
