Published: January 2024

El presente proyecto considera los cambios en los procesos que se vienen implementando en la gestión turística, debido a la introducción de aplicaciones informáticas que en su interior tienen incorporados algoritmos de inteligencia artificial que contribuyen a que muchos usuarios que necesitan algún producto o servicio turístico puedan solicitar información, reservar o comprar, de forma virtual, sin intermediación de personas y/o empresas. Como parte de la metodología se realizó la revisión bibliográfica de artículos relacionados con la inteligencia artificial en general y su utilización en Turismo; se aplicó una encuesta que dio como resultados que, para planificar viajes, los encuestados usan tecnologías de IA, la más utilizada para reserva de pasajes aéreos es despegar.com; alojamiento, booking.com; alquiler de vehículos, es.kayak.com; y, para consumo de alimentos la mayoría no utiliza aplicaciones. A través de la información consultada del uso de IA en España se encontró datos similares a los levantados en la población encuestada, donde la inteligencia artificial ha ido descartando, en los últimos años, la contratación de empresas operadoras turísticas. Con los datos obtenidos se concluyó que la mayoría de los encuestados emplea tecnologías de inteligencia artificial en sus viajes dejando de lado el servicio de las agencias de viajes.

Re-description of Parasphaerosyllis indica Monro, 1937 (Annelida, Syllidae), with the establishment of a new species from western Mexico
Authors: Góngora-Garza Gerardo , Tovar-Hernández María , de León-González Jesús Angel 
Published: January 2024

Parasphaerosyllis Monro, 1937 is a syllid genus, currently composed of four species: P. indica Monro, 1937 from the Arabian Sea, P. uschakovi (Chlebovitsch, 1959) from the Kurile Islands, P. ezoensis Imajima & Hartman, 1964 from Japan and P. malimalii Capa, San Martín & López, 2001 from the Pacific coast of Panama. The distribution of P. indica is circum-tropical to temperate waters, but the presence of species complexes has been suggested. In order to clarify the distribution of P. indica in many areas of the world, a re-description, based on examination of the type material, is required as a first step to a better understanding of its diagnostic features.
Parasphaerosyllis indica is re-described, based on holotype examination, a new species is established from the Gulf of California and Parasphaerosyllis malimalii is reported for the first time since its description in 2001. Parasphaerosyllis irregulata sp. nov. is distinguished from its congeners by the following features: 1) Palps are free at their base; 2) Two types of dorsal cirri are present: spherical to bulbous and moniliform cirri; 3) Both types of cirri are distributed irregularly. A spherical/bulbous and moniliform cirrus may appear together within the same segment (asymmetrical segment) or only a spherical/bulbous cirrus may appear in several consecutive segments (not alternating as occurs in congeners); 4) The spherical/bulbous cirri may have distal knobs with 1–3 terminal articles; and 5) Bidentate falcigers with short, sub-triangular blades with a proximal tooth slightly larger that the distal one. A taxonomic key to species of Parasphaerosyllis species is included.

Published: January 2024

Abstract

Background:
Non-pharmacologic prophylactic methods for chronic migraine have been developed, including the promising non-invasive techniques of repetitive transcranial magnetic stimulation (rTMS) and transcranial direct-current stimulation (tDCS). This study aimed to compare the efficacy of rTMS and tDCS on pain intensity, the impact of headaches on daily life, anxiety, and depression in migraine headaches patients.

Materials and Methods:
This randomized clinical trial was conducted on 72 patients with migraine headaches, randomly allocated to the rTMS and tDCS groups. Participants received 3 and 12 sessions of stimulation over the left dorsolateral prefrontal cortex (DLPFC), respectively. Follow-up measurements, including pain intensity, anxiety, depression, and impact on daily life, were performed one month after the last sessions. Analyses were done by IBM SPSS statistics version 26 software.

Results:
Of 72 patients enrolled in the study, 19 were male (8 in the rTMS group and 11 in the tDCS group). There was no significant difference in baseline characteristics between groups. During the follow-up visit, both groups showed a decrease in anxiety levels (P values = 0.005 and 0.015), while only the rTMS group displayed a significant improvement in depression (P value = 0.01). However, no statistically significant difference was found among the groups regarding changes in pain intensity, anxiety, and the impact of headaches on daily life (P values >0.05).

Conclusion:
Our findings suggest that both rTMS and tDCS may be effective in reducing pain intensity and improving the impact of headaches on daily life and anxiety in patients with chronic migraine. However, significant improvement in depression was only observed in the rTMS group patients.

Published: January 2024

Background
Ventral hernia can be defined as noninguinal and nonhiatal hernia in the fascia of the abdominal wall. Laparoscopic repair become a popular method with decreased overall complications nowadays. We aimed to provide an efficient management for ventral hernia through comparison of quality of life (QoL) postlaparoscopic and open techniques according to European registry for abdominal wall hernias quality of life (EuraHS-QOL) score.

Patients and methods
The data of 54 patients with primary ventral hernia were collected prospectively. Of these patients, 27 underwent open repair, and 27 underwent laparoscopic repair after excluding patients with a complicated and recurrent ventral hernia and incisional hernia. Perioperative QoL was assessed according to the EuraHS score.

Results
Two groups were designed, each including 27 patients. The most common complication was seroma (25.9%) in open repair, followed by infection (18.5%), while only one case in laparoscopic repair had port site infection; the difference was statistically significant (P<0.05). The mean operative time in open repair was 51.2±5.1 and 89.7±9.5 in laparoscopic repair; the difference was highly significant (P<0.001). The mean length of stay in the hospital was 23.1±7.3, and it was 19.1±6 in laparoscopic repair; the difference was significant (P<0.05). All cases in open repair had subcutaneous drain; but not in laparoscopic repair; the difference was highly significant (P<0.001). The EuraHS score in all its items was significant in favor of laparoscopic repair.

Conclusion
Laparoscopic repair was associated with high QoL, less complications, and recovery time as compared with open repair of ventral hernia.

Published: January 2024

Background
Anismus is a functional disorder characterized by dyssynergia and incoordination of pelvic floor muscular contractions at defecation. Despite normal propulsive power used when attempting to defecate, a hypertonic pelvic floor dysfunction results in nonrelaxation or even paradoxical contraction of puborectalis muscle, resulting in failure to straighten the anorectal angle, hence impaired stool evacuation. This study aims at evaluating the outcome of injection of botulinum toxin type-A (BTX-A) in puborectalis muscle in patients with anismus.

Patients and methods
The study included 50 patients who were presented with symptoms of obstructed defecation (OD) and were diagnosed as anismus and failed conservative treatment and biofeedback training. Ultrasound-guided BTX-A injections into puborectalis muscle were done. All patients were followed up for 6 months for OD symptoms and manometric findings.

Results
The current study included 50 patients with a mean age of 36.6±11.9 years presented with anismus for a mean duration of 6.8±2.64 months.
There was a statistically significant improvement in the Longo score of OD at 1, 3, and 6 months when compared with the initial values (P<0.001), while there was no statistically significant difference noticed in the defecation frequency at 3 and 6 months when compared with the initial records.
There was a statistically significant decrease in both resting and squeeze pressures after 3 and 6 months when compared with the initial records (P<0.001).
The overall satisfaction significantly increased to 68 and 64% after 3 and 6 months, respectively, when compared with 0% satisfaction reported at the initial assessment.

Conclusion
According to the current results, injection of BTX-A therapy in puborectalis muscle in patients with anismus is assumed to be effective for short term with good overall satisfaction.

Authors: Sehsah Tarek M. , Elshora Ahmed A. , Abd-Raboh Osama H. 
Published: January 2024

Background
Repairing of ventral and incisional hernias is a frequently performed surgical intervention in the field of general surgery; this work aimed to compare the extended totally extraperitoneal (eTEP) technique to the intraperitoneal onlay mesh (IPOM) technique for ventral hernias regarding feasibility, cost, operative, and postoperative outcomes of both techniques.

Patients and methods
This randomized controlled study was conducted on 50 patients complaining of ventral hernia. These patients were admitted to Tanta University Hospitals, Egypt, from January 2021 to January 2023. Patients were divided according to the technique used into two2 equal groups: group eTEP (study group): 25 participants were submitted to eTEP repair. Group IPOM (control group): 25 patients were submitted to IPOM repair.

Results
Demographic data were insignificantly different between both groups. Operation time was significantly prolonged in group eTEP compared to group IPOM (P<0.001). Cost and hospital stay were significantly decreased in group eTEP compared with group IPOM (P<0.05). Pain at rest and restriction to normal activity were significantly lower on the first and 14th postoperative days in group eTEP compared with group IPOM (P<0.05). Cosmesis was insignificantly different on the first and 14th postoperative days between both groups. Postoperative seroma, postoperative recurrence, and postoperative ileus were insignificantly different between both groups.

Conclusion
Both eTEP and IPOM demonstrated safety and efficacy in the treatment of de-novo ventral hernia repair (comparable few complications in both groups with no recurrence in this study) with superiority toward eTEP as evidenced by lower hospital stay, cost, postoperative pain, and early return to normal activity.

Published: January 2024

Background and objectives
Tumor size has been identified as a critical prognostic factor after pancreatic adenocarcinoma resection; however, this is still up for debate. The authors aimed to investigate the relationship between size and the results of pancreatic cancer resection.

Patients and methods
The studied subjects were divided into two groups as follows: group A: included 69 patients with pancreatic head/uncinate process tumor ≤3 cm in size (maximum tumor diameter), subjected to elective pancreaticoduodenectomy, group B: included 87 patients with pancreatic head/uncinate process tumor >3 cm in size (maximum tumor diameter), subjected to elective pancreaticoduodenectomy.
From January 1, 2016 to December 31, 2021, at Menoufia University’s National Liver Institute, we looked at the clinical, radiological, histological, and survival characteristics of tiny pancreatic cancer tumors (tumors ≤3 cm) in comparison to tumors above 3 cm in size following pancreaticoduodenectomy. Calculations were made of overall cancer-specific survivals. Key factors were assessed for relevance in survival prediction using a Cox proportional hazards model.

Results
Among the tumors measured, 44.2% were ≤3 cm in size 55.8% tumor were greater than 3 cm in size. Larger tumors were associated with worse symptoms, higher Ca19.9, more progressive TNM stages, longer operative time, more blood transfusion, higher grade, more vascular invasion, more involved surgical margin, and more lymph node invasion. Our study compared data of 1-year survival rates of 79.1% and 50% as seen with ≤3 cm tumor size and with above 3 cm tumor size, respectively, also 2-year survival rates of 40.3% and 19.2% were seen with ≤3 cm tumor size and with above 3 cm tumor size, respectively, the result being statistically significant (P<0.001). Pancreatic ductal adenocarcinoma size above 3 cm was associated with a worse prognosis together with histologic grading, vascular invasion, involved surgical margin, longer waiting list time, and progressive T stages.

Conclusions
Our findings suggest that early pancreatic ductal adenocarcinoma detection can have clinical benefits, which has positive implications for future screening strategies. Pancreatic ductal adenocarcinoma size above 3 cm is an independent predictive factor for poor prognosis after surgical resection and is associated with more aggressive tumor biology. Future trials are required to evaluate the survival benefit of neoadjuvant therapy in this subset of patients.

Published: January 2024

Background
Laparoscopic surgery is now the accepted method of choice for practically all abdominal procedures. A number of trocar site closure techniques have been developed, but many of them are unaffordable and/or difficult to employ.

Patients and methods
The objective of this prospective interventional study is to assess the duration required to close the trocar site, the incidence of hemorrhage or other postoperative problems, and the safety and effectiveness of a novel fascial closure technique (the Madany closure). Patients who were eligible for laparoscopic cholecystectomy at the Aswan University Hospital’s General Surgery Department were included.

Results
One hundred and thirty patients were included in our study. Most of the participants were females, representing 93.08% of patients. The mean age of participants was 40.07±10.02 years, and the median (interquartile range) total time for the complete closure of the port site was 83.5 s (44.75 s). After the follow-up period of 6 months, no patient developed a trocar-site hernia.

Conclusion
The Madany closure technique provides a safe, fast, and effective technique for the closure of laparoscopic port sites.
Comparative study of outcomes of different approaches in redo mitral valve surgery
Authors: Radwan Mohaned M.M. , Sewielam Mohamed I. , Shawky Hisham A.F. 
Published: January 2024

Background
Redo mitral valve replacement surgery is a challenging procedure as the access of the mitral valve mandates good exposure yet mitral visualization may not be sufficient as previous cardiac operations may complicate mitral valve exposure, as adhesions and loss of mobility in the surrounding tissues may be present. In such cases, the conventional left atrial incision may not offer satisfactory visualization in the surgical site of the valve. Therefore, several alternative approaches have been proposed, such as superior trans-septal approach, for satisfactory visualization of the mitral valve intra-operatively.

Patients and methods
Between January 2017 and November 2021, 100 patients were enrolled and with 50 patients randomly assigned in each group. Group one on patients undergoing redo surgery via a superior trans-septal approach and group two undergoing redo surgery via left atrial approach.

Results
Transeptal approach provides same results like left atrial approach in redo mitral valve surgery.

Conclusion
We conclude that the transseptal approach when compared to left atrial in redo patients provides comparable results in the intraoperative as well as postoperative outcomes
Laparoscopic mini-gastric bypass versus laparoscopic Roux-en-Y gastric bypass in redosurgery after failed vertical banded gastroplasty with long gastric pouch
Authors: Zaid Mohamed H. , Sabry Ahmed M. , Khalil Ahmed 
Published: January 2024

Background
Up to 50% of patients who undergo vertical band gastroplasty (VBG) experienced weight regain or complications, like band erosion or slippage, within 5–10 years of the procedure, the aim of the study to evaluate laparoscopic mini-gastric bypass versus laparoscopic Roux-en-Y gastric bypass as a redosurgery after failed VBG.

Patients and methods
We analyzed the data of 102 patients (38 males and 64 females) underwent revisional surgery after failed VBGs from July 2021 to August 2022, with mean age 45.92 years, follow up for 1 year in Ain Shams University Hospitals.

Results
The mean hospital stay was 1.8 days (1–4 days), 2.9 days (2–7 days) in Redo laparoscopic mini gastric bypass (R-LMNGB) and Redo laparoscopic roux en Y gastric bypass (R-LRYGB) respectively. Postoperative BMI after 1 year 31.16±27.83 and 31.94±3.69 in R-LMNGB and R-LRYGB, respectively, %EWL show significant difference between two groups after 3 months and 1 year. Postoperative complications rates were 3.92% in R-LRYGB.

Conclusions
R-LMNGB after failed VBG has almost the same results of R-LRYGB as regard weight loss, improvement of obesity-related comorbidities with less operative time, hospital stay, less anastomosis, and complications.
Penetrating anterior abdominal stab wounds: is exploratory laparotomy mandatory?
Authors: Abdallah Hassan A. , Kabbash Mansour M. , Saad Mohamed Rabie 
Published: January 2024

Background
Despite the consensus that patients with penetrating anterior abdominal stab wounds (AASWs) who presented with shock, diffuse peritonitis, or evisceration should be offered immediate laparotomy, the treatment of stable patients with negative abdominal examination is a bit controversial. It seems that selective nonoperative management (SNOM) of stable patients is picking up steam.

Aim
This study aimed to evaluate our experience in treating AASW patients and assess the safety and efficacy of the SNOM of AASWs.

Patients and methods
From March 2023 to October 2023, this study was conducted at the Aswan University Hospital’s General Surgery Department. It involved 69 patients with penetrating AASWs. Group I: 31 hemodynamically stable patients who showed no signs of peritonitis underwent local wound exploration and were monitored with serial examinations. Group II: 38 individuals had evisceration, shock, and peritonitis treated by emergency laparotomy.

Results
Group I patients had successful nonoperative management in 83.87% of cases. The remaining 16% had delayed laparotomies, all of which were therapeutic. In group II, out of the 38 patients who had emergency laparotomies, 21% had unnecessary laparotomies. By combining selective management with diagnostic tests, we were able to bring the rate of unnecessary laparotomies down to zero. Complications occurred in 12.5% of patients who had an unnecessary laparotomy.

Conclusion
The SNOM of AASW patients who are asymptomatic or minimally symptomatic allows for a large reduction in unnecessary laparotomies.

Authors: Abdelaziz Asaad A. , Erfan Moatasem A. , Elian Mohammad A. 
Published: January 2024

Objective
The choice between a stapler and a hand-sewn intestinal anastomosis is based on surgical experience as well as individual preference. The purpose of the study was to compare the results of hand-sewn versus stapled anastomoses in urgent intestinal procedures.

Patients and methods
The study included 96 patients who, between October 2020 and October 2022, received emergency intestinal anastomoses at our associated university institutions. Randomly selected patients were assigned to two groups: group A (n=50) received stapled anastomoses, and group B (n=46) received hand-sewn anastomoses.

Results
Patient information, duration of operation, anastomotic leak incidence, and complications following surgery were all documented.

Findings
Group A’s operating time was substantially less (P=0.0001). There was no discernible difference in blood loss, leakage rate, wound infection, or mortality between the two groups.
