Background: "Rendez-vous" (RV) technique is a mixed-technique which uses both laparoscopic and endoscopic skills; however, the evidence is contradictory regarding the implementation of this technique or the 2-step sequential technique (endoscopic retrograde cholangiopancreatography [ERCP] followed by laparoscopic cholecystectomy [LC]) in the management of cholecysto-choledocholitiasis.

Objective: To estimate the association between the implementation of RV technique and the presence of post-surgical complications as primary outcome, using as comparator the 2-step sequential technique.

Method: An observational, analytical, retrospective study was conducted, using as exposed cohort the medical records from patients with a diagnosis of cholelithiasis, cholecystitis, or mild biliary pancreatitis. The exposed cohort underwent RV technique, while the unexposed cohort were those which underwent two step technique.

Results: There was a lower post-surgical complication rate in the RV group (0%) compared with the 10.1% (p = 0.3617) in the control group. Also, RV technique showed a lesser hospitalization time (p = 0.0377) and a lesser post-surgical hospitalization time (p < 0.0001).

Conclusions: RV technique is superior when compared with the 2-step sequential technique (ERCP followed by LC), based on a better surgical success rate, a fewer complications rate and less hospitalization time.

Rosai Dorfman Destombes (RDD) disease is a non-Langerhans histiocytosis. The central nervous system is affected in < 5% of cases. We report the case of a 59-year-old man, who began 8 months before admission with headache, diminished visual acuity in the temporal hemifields, hyposmia, and seizures. Magnetic resonance imaging showed three midline skull-base lesions in anterior, media, and posterior fossae. We performed a complete resection of symptomatic lesions using a bifrontal craniotomy. The histopathological analysis determined RDD, therefore, we started steroid treatment. Our case description is due to the diagnosis and location, one of the rarest reported to date in the literature.

Background: The incidence of retropancreatic lymph node metastasis in gastric cancer patients is not negligible.

Aim: The aim of present study was to determine the risk factors for retropancreatic lymph node (LN) metastasis and to investigate its clinical significance.

Patients and methods: Clinical pathologic data of 237 patients with gastric cancer between June 2012 and June 2017 were analyzed retrospectively.

Results: 14 patients (5.9%) had retropancreatic LN metastases. The median survival of patients with and without retropancreatic LN metastasis was 13.1 and 25.7 months. According to univariate analysis; tumor size ≥ 8 cm, Bormann type III/IV, undifferentiated type, presence of angiolymphatic invasion, depth of invasion (pT4), N3 stage, No. 3, No. 7, No. 8, No. 9, and No. 12p LN metastasis was found to be associated with retropancreatic LN metastasis. According to multivariate analysis; tumor size ≥ 8 cm, Bormann type III/IV, undifferentiated type, pT4, N3 stage, No. 9 LN metastasis, and No. 12p LN metastasis were found to be independent prognostic variables for retropancreatic LN metastasis.

Conclusion: Retropancreatic LN metastasis is a poor prognostic factor for gastric cancer. Tumor size (≥ 8 cm), Bormann type III/IV, undifferentiated tumor, pT4, N3 stage, and No. 9 and No. 12p LN metastasis are risk factors for metastasis to retropancreatic lymph node.

Background: Distal radius fractures are very frequent fractures in the world, so it is necessary to establish new rehabilitation strategies.

Objective: To determine the effectiveness of tele rehabilitation versus supervised treatment in the functional recovery of patients with distal radius fracture.

Method: A randomized clinical trial was conducted that included 91 patients with distal radius fractures grades AO23 A and AO23B, which were randomly assigned to a treatment group, the supervised rehabilitation group received for two weeks a program of 10 treatment sessions and the tele rehabilitation group received through the Moodle platform instructions to carry out the rehabilitation program. Outcome measures (functionality, active range of motion, hand grip strength, quality of life and pain) were measured at the time of admission to rehabilitation and at 1, 3 and 6 months.

Results: In both treatment groups at 6 months, statistically significant intragroup differences in functionality were demonstrated, with no intergroup differences.

Conclusions: At 6 months, both rehabilitation programs increase functionality, range of motion, quality of life and decrease pain, without statistically significant differences intergroup.

Background: Complication treatment in colorectal cancer can be carried out quickly with the prediction and early diagnosis. However, there is no apparent predictive factor for this.

Objective: We aimed to determine the factors that predict early mortality and morbidity in patients who underwent laparoscopic right hemicolectomy and their superiority over each other.

Method: Demographic data, age-adjusted Charlson Comorbidity Index, American Society of Anesthesiologists Score, body mass index, modified-Glasgow Prognostic Score (mGPS), stage of disease, and sarcopenia were evaluated in patients who underwent right hemicolectomy between 2010-2022. Their superiority in predicting short-term outcomes was compared.

Results: 78 patients were included in the study. The complication rate was higher in sarcopenic patients (p = 0.002). A high mGPS score was associated with increased mortality risk (p = 0.012). Other methods were not found to be related to short-term results.

Conclusion: Sarcopenia is useful for the prediction of complications, and the mortality rate can be estimated by the mGPS score. These are superior to the other short-term results prediction methods. However, randomized controlled studies are needed.

Tracheoesophageal fistulas (TEFs) are common in clinical practice and we address them in different ways according to their etiologies. Herein, we present a case of tracheomegaly combined with a TEF after long-term tracheotomy. We placed a modified silicone stent into the trachea to simultaneously cover the fistula and maintain an artificial airway for ventilation. After migration of the modified stent, we replaced it with a prolonged tracheotomy tube. This modified stent is a novel clinical attempt at addressing TEFs that should be more thoroughly explored.

Undifferentiated pleomorphic sarcoma (UPS) is a very aggressive malignant tumor that originates in bone or soft tissues, being its most frequent location in the extremities. We present the case of a 71-year-old man who, two years of follow-up after a lower right limb UPS excision surgery, presented a single metastasis of sarcomatoid origin in the pancreas that was treated by cephalic pancreaticoduodenectomy. Sarcomatoid metastases to the pancreas are extremely rare. Resection of the metastasis is the only therapeutic alternative that has reported benefit in terms of the survival of these patients.

Background: Fractures of the atrophic mandible have been historically treated in various ways, from intermaxillary fixation to internal fixation, some cases require bone grafts. Besides, the Luhr classification serves as a guide to select the type of treatment.

Objective: To show the treatment of fractures in atrophic mandible with plates and screws, and the potential indications of bone graft in this type of fractures.

Method: We presented a serie of 17 patients with atrophic mandible treated with plates and screws, some of them no blocked system and other with locked screws. For patients in luhr classes II and III cancellous bone grafts were used, looking for best osteogenic response, harvesting for the proximal third of the tibia.

Results: Postoperative progress was generally uneventful. Oral intake with purees was resumed 24 hours after surgery, as well as ambulation. Fracture healing at 6 months was seen in 17 patients. One patient died before the 6-month time point as the result of a stroke. Delayed union was diagnosed 3 months after surgery in another patient, who refused secondary treatment.

Conclusions: Treatment of fractures in atrophic mandibles with plates and screws is a reliable procedure. Luhr classification provide useful guidance regarding the use of bone grafts for best osteogenic response in the fracture. This treatment allows a quick restart of the feeding by mouth and movilization of the patients.

Background: Giant paratubal cysts are mostly benign tumors, with an incidence of 10%. The incidence rate of neoplasms is 2% to 3%, including papillary carcinoma and serous papillary neoplasms.

Case report: A 35-year-old woman who began her current condition 3 years after her pregnancy, with urgency when urinating, abdominal pain and sensation of abdominal mass, who was diagnosed and protocolized in a second public level hospital of the State of Mexico, treated with open surgery, and good postoperative evolution.
