OBJECTIVES
Esophageal perforations are a complex clinical scenario that have been poorly studied. To date, there is no grading of esophageal perforations, the reason being that the outcome is very heterogeneous, because the perforation is very heterogeneous. A grading of the severity of the perforation may guide treatment, and could ultimately affect morbidity and mortality.
METHODS
The observation period of the study was four years. All patients with a perforation of the esophagus aged 18 to 90 years were included. All anastomotic insufficiencies or fistulas after surgery of the esophagus were excluded. The cause of the injury and the time interval between the event and the start of therapy were analyzed. The severity of each perforation was classified based on the results of a diagnostic CT scan, gastroscopy as well as clinical and laboratory findings. Therapy and signs of infection were evaluated. Endpoints of the study were patient recovery or death. The study was conducted as a retrospective single-center study at a university hospital of Düsseldorf. The study has been approved by the review board. Patients gave their informed consent before data collection. All data were analyzed using SPSS 29 (IBM SPSS Statistics software).
RESULTS
Age, gender and cause of the esophageal perforation did not impact significantly on overall survival. The duration of injury > 24 h (p = 0.01), presence of mediastinitis (p = 0.01) and necrosis of the esophagus (p = 0.02) were associated with an unfavorable outcome. The correlation of the clinical grading of the severity of the perforation based on the endoscopic, radiological and clinical findings with the overall survival of patients was significant. Patients categorized into the four grades of severity (I-IV) had an overall survival of 100%, 100%, 70% and 50%, respectively.
CONCLUSION
The severity of esophageal perforations can be systematically rated grades I to IV based on the radiological, endoscopic and clinical findings at diagnosis. Due to the grading and its correlation to the overall survival, a comparison of patients, their treatment and outcome becomes possible. In future, the grade of a perforation may guide treatment, and therefore affect morbidity and mortality.

Cases of battery ingestion are well documented in the scientific literature, especially concerning button cell battery ingestion in children. In this instance, the authors present an atypical case of a young man who voluntarily ingested a cylindrical alkaline battery containing manganese. The patient died approximately a week later, despite not exhibiting any specific symptoms. The battery was found in the cecum during the autopsy, showing deterioration at its positive pole. The cecal mucosa exhibited two ulcerations without perforation. Histological analysis revealed intestinal ischemia in the cecum, with no microscopic lesions in other organs. Toxicology reports indicated high levels of manganese in both cardiac and peripheral blood. Considering all the results from the additional analyses, the experts concluded that the death was likely of multifactorial origin, associated with a toxic blood concentration of manganese. To the best of our knowledge, this is the first recorded death following the ingestion of a cylindrical battery, and the first instance of manganese intoxication resulting from the ingestion of an alkaline battery. The authors will present the case and provide a literature review to assess the extent to which the presence of manganese may have contributed to the fatality.

PURPOSE
To describe residual arterial supply to the stomach after bariatric surgery via a systematic arterial-phase CT assessment approach that can aid in diagnosis and treatment of postoperative complications and facilitate planning for future procedures.
METHODS
Arterial-phase CT of 46 patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) at 3 academic institutions were retrospectively reviewed to assess patency of left gastric artery (LGA), right gastric artery (RGA), gastroepiploic artery (GEA), and left inferior phrenic artery (LIPA) and presence of gastric perforators.
RESULTS
In 25 RYGB and 21 SG patients, mean diameters were LGA 2.2 ± 0.4 mm, RGA 1.6 ± 0.5 mm, and GEA 1.7 ± 0.4 mm. On RYGB scans, all LGAs, RGAs, and 24/25 (96%) of GEAs were identified. Excellent to good patency was seen in 20/25 (80%) LGAs, 21/25 (84%) RGAs, and 23/24 (96%) GEAs. On SG scans, all LGAs, 18/21 (86%) of RGAs, and 20/21 (95%) GEAs were identified. Excellent to good patency was seen in 17/21 (81%) LGAs, 15/18 (83%) RGAs, and 20/20 (100%) GEAs. In terms of gastric perforators, LGA supply was seen on 23/25 (92%) of RYGB and 17/17 (100%) of SG scans. RGA supply was seen on 13/21 (62%) RYGB and 9/18 (50%) SG scans. GEA supply was seen on 19/23 (83%) RYGB scans. No gastric supply via GEA was seen on SG scans.
CONCLUSION
In this study, arterial supply to the stomach through the LGA was consistently identified in all RYGB and SG cases, indicating an uncomplicated surgical approach with regard to preserving the LGA. Dedicated CT angiography protocol or catheter-directed angiography is recommended for accurate and comprehensive assessment of the gastric blood supply, particularly before surgical re-intervention.

Cervical cancer is one of the most common malignant tumors in women, and more than one-third of the patients have already developed to a locally advanced stage at initial diagnosis. After standard concurrent chemoradiotherapy, recurrence still occurs in 29-38% of patients with locally advanced cervical cancer (LACC), and the 5-year survival rate of patients with recurrence is only 3.8-13.0%, resulting in a poor prognosis and limited therapeutic choices. Currently, the recommended first-line systemic treatment for recurrent metastatic cervical cancer involves cisplatin or carboplatin in combination with paclitaxel-based chemotherapy, supplemented with the antivascular agent bevacizumab and the immune checkpoint inhibitor pembrolizumab. The use of these drugs, however, is limited due to side effects such as myelosuppression, gastrointestinal perforation, and bleeding, so new treatment modalities need to be explored. Anti-EGFR (epithelial growth factor receptor, anti-surface growth factor receptor antibody) targeted drugs have been demonstrated to have a significant radiosensitizing effect on synchronous chemoradiotherapy in LACC and are now considered to have potential for the treatment of recurrent cervical cancer. We represented a LACC patient who relapsed 6 months after concurrent chemoradiotherapy. The patient received six cycles of nimotuzumab combined with camrelizumab, and the efficacy was evaluated to be partial remission after two or four cycles of treatment, with progression-free survival up to 9 months, without significant side effects. Until March 2024, the patient was still undergoing treatment. Promising efficacy and tolerable side effects of nimotuzumab in combination with camrelizumab were observed in this case.

To investigate the effect of zirconia personalized gingival structure on peri-implant soft and hard tissue stability after single-tooth implant restorations in patients with thin gingival biotypes in the anterior region, with a view to provide a clinical guideline. This retrospective study included 20 patients with thin gingival biotype and implant restorations in the anterior region. These patients included 9 males and 11 females, and the age was (35.2±10.3) years. The patients were from the Department of Periodontal Implantology, Stomatology Hospital, Southern Medical University from January 2018 to December 2022. Computer-aided design/computer-aided manufacturing (CAD/CAM) techniques were used to fabricate a titanium base zirconia personalized gingival structure to maintain the soft-tissue perforated gingival contour of the anterior esthetic zone. This structure consists of two modalities: titanium base + zirconia outer crown or titanium base personalized zirconia abutment + zirconia outer crown. Clinical outcomes were recorded immediately and after delivery of the final restorations. Implant retention was recorded, esthetic scoring was performed using the pink esthetic index, the amount of bone resorption at the implant margins was measured based on digitized apical radiographs, and periodontal health was evaluated using the modified plaque index and the modified bleeding index. The survival rate of the 20 implants was 100% after 3 years of wearing the final restorations, with a pink aesthetic score of 9.3±0.9. Bone resorption at the proximal and distal mesial margins of the implants was 0.09 (-0.21, 0.20) mm, 0.17 (-0.12, 0.27) mm after 3 years, respectively, and the difference was not statistically significant when compared to bone resorption immediately after placement of the final restoration (0) (-1.03, 0.394; -2.05, 0.065). Zirconia personalized gingival structure maintains the stability of peri-implant hard and soft tissues of thin gingival biotypes in the anterior region.

Comparative Study
Comparative evaluation and co-relation in variation of curve of Spee and curve of Wilson in Class II div. 1, Class II div. 2, and Class III as against Class I malocclusion in central India population- an in vitro study.
INTRODUCTION
Getting acceptable cosmetic results in the soft tissues of the face serves as the foundation for orthodontic treatment planning. Also, in order to achieve healthy static and dynamic occlusal interactions, the teeth must be positioned within the basal bone at the correct position, angle, and inclination. To avoid periodontal issues, provide stability, and achieve a functional occlusion, it is essential to ascertain the individual's dental arch form before starting of treatment and thus to utilise the mechanics that follow throughout the treatment.
OBJECTIVES
To evaluate and compare variation in Curve of Spee and Curve of Wilson in Class II Div.-1, Class II-Div-2 and Class-III as against Class I malocclusion in central India population.
METHODOLOGY
Irreversible hydrocolloid impression will be taken with perforated metal stock trays and stone cast will be poured. This will be scanned using CAD CAM machine and curve of Spee and Wilson will be measured using reverse engineering.
EXPECTED RESULT
It will assist us in treatment planning for preventing periodontal issues, assuring stability, and achieving functional occlusion by evaluating and comparing the Spee and Wilson curves in Class II Divison-1, Class II Divison-2, and Class-III malocclusion with Class-I malocclusion.
CONCLUSION
Every single patient receiving orthodontic treatment has the COS, which is crucial to achieving a stable occlusion. Almost every patient who receives orthodontic treatment eventually experiences the Spee Curve. Since there aren't many studies examining the relationship between the Curves of Spee and Wilson, their impact on dentoskeletal morphology, and their role in occlusal stability.

BACKGROUND
The potential of robot-assisted surgery in plastic and reconstructive surgery remains to be established, especially in free tissue transfer. This prospective study aimed to present our experience and findings from the first 50 consecutive cases of robot-assisted microsurgery using the Symani surgical system.
METHODS
A prospective database was maintained, recording patient demographics and surgical details for all cases of robot-assisted microsurgery in a large academic institution. All surgeons underwent an intensive training program with the Symani surgical system.
RESULTS
A total of 50 patients who underwent robot-assisted microsurgical reconstruction were identified. Free microsurgical tissue transfer was performed in 45 cases, targeted muscle reinnervation in four cases, and lymphovenous anastomoses in a single case. A total of 94 robot-assisted anastomoses and coaptations were performed, (46 venous and 30 arterial anastomoses, 16 nerve coaptations, two lymphovenous anastomoses). Six cases involved perforator-to-perforator anastomoses. Ninety-eight percent of attempted anastomoses were completed using the robot. Size-mismatch anastomoses, seen in 37.8% of cases, took significantly longer. Minor complications occurred in three cases and major in six cases. There were three cases of microvascular compromise requiring revision. One partial flap loss and no complete flap loss occurred.
CONCLUSIONS
Our study highlights the immense potential of robot-assisted microsurgery, and a feasible and effective modality for various microsurgical procedures, with outcomes comparable to those of conventional microsurgery. Despite challenges, such as increased operating times and higher costs, the technology offers significant advantages, such as enhanced precision and motion scaling. We identify a slow learning curve and a necessity for higher caseloads.

Flap necrosis continues to occur in skin free flap autologous breast reconstruction. Therefore, we investigated the benefits of indocyanine green angiography (ICGA) using quantitative parameters for the objective, perioperative evaluation of flap perfusion. In addition, we investigated the feasibility of hyperspectral (HSI) and thermal imaging (TI) for postoperative flap monitoring. A single-center, prospective observational study was performed on 15 patients who underwent deep inferior epigastric perforator (DIEP) flap breast reconstruction (n=21). DIEP-flap perfusion was evaluated using ICGA, HSI, and TI using a standardized imaging protocol. The ICGA perfusion curves and derived parameters, HSI extracted oxyhemoglobin (oxyHb) and deoxyhemoglobin (deoxyHb) values, and flap temperatures from TI were analyzed and correlated to the clinical outcomes. Post-hoc quantitative analysis of intraoperatively collected data of ICGA application accurately distinguished between adequately and insufficiently perfused DIEP flaps. ICG perfusion curves identified the lack of arterial inflow (n=2) and occlusion of the venous outflow (n=1). In addition, a postoperatively detected partial flap epidermolysis could have been predicted based on intraoperative quantitative ICGA data. During postoperative monitoring, HSI was used to identify impaired perfusion areas within the DIEP flap based on deoxyHb levels. The results of this study showed a limited added value of TI. Quantitative, post-hoc analysis of ICGA data produced objective and reproducible parameters that enabled the intraoperative detection of arterial and venous congested DIEP flaps. HSI appeared to be a promising technique for postoperative flap perfusion assessment. A diagnostic accuracy study is needed to investigate ICGA and HSI parameters in real-time and demonstrate their clinical benefit.

BACKGROUND
The technological evolution of bronchoscopy has led to the widespread adoption of flexible techniques and their use for both diagnostic and therapeutic purposes. Currently, there is an active debate regarding the comparative efficacy and safety of rigid flexible bronchoscopy in the treatment of foreign body aspiration.
AIM
To evaluate our experience with tracheobronchial foreign body extraction using flexible bronchoscopy and provide a literature overview.
METHODS
This was a single-centre retrospective study. Twenty-four patients were enrolled between January 2017 and January 2023. Medical records of patients aged below 18 years who were admitted to authors' affiliated institution with a suspected diagnosis of foreign body aspiration were collected from hospital's database to Microsoft Excel 2019. Data were analysed using MedCalc Statistical Software.
RESULTS
Patient ages varied from 9 months to 11 years. The median age was 23.5 months, 95% confidence interval (CI) 19.49-44.77. We observed age clustering in children with foreign body aspiration at our institution with three age subgroups: (1) 0-25 months; (2) 40-60 months; and (3) 120-140 months. We expectancy of an organic tracheobronchial foreign body was significantly higher in 0-25 months subgroup than that in older ones when subgroups 40-60 and 120-140 months were combined together (odds ratio = 10.0, 95%CI: 1.44-29.26, = 0.0197). Successful foreign body extraction was performed in all cases. Conversion to a rigid bronchoscope was not required in any of the cases. No major complications (massive bleeding, tracheobronchial tree perforation, or asphyxia) were observed.
CONCLUSION
Flexible bronchoscopy is an effective and safe method for tracheobronchial foreign body extraction in children.

BACKGROUND
Endoscopic management is the first-line therapy for post-liver-transplant anastomotic strictures. Although the optimal duration of treatment with plastic stents has been reported to be 8-12 months, data on safety and duration for metal stents in this setting is scarce. Due to limited access to endoscopic retrograde cholangiopancreatography (ERCP) during the coronavirus disease 2019 pandemic in our centre, there was a change in practice towards increased usage and length-of-stay of the Kaffes biliary intraductal self-expanding stent in patients with suitable anatomy. This was mainly due to the theoretical benefit of Kaffes stents allowing for longer indwelling periods compared to the traditional plastic stents.
AIM
To compare the safety and efficacy profile of different stenting durations using Kaffes stents.
METHODS
Adult liver transplant recipients aged 18 years and above who underwent ERCP were retrospectively identified during a 10-year period through a database query. Unplanned admissions post-Kaffes stent insertion were identified manually through electronic and scanned medical records. The main outcome was the incidence of complications when stents were left indwelling for 3 months 6 months. Stent efficacy was calculated rates of stricture recurrence between patients that had stenting courses for ≤ 120 d or > 120 d.
RESULTS
During the study period, a total of 66 ERCPs with Kaffes insertion were performed in 54 patients throughout their stenting course. In 33 ERCPs, the stent was removed or exchanged on a 3-month interval. No pancreatitis, perforations or deaths occurred. Minor post-ERCP complications were similar between the 3-month (abdominal pain and intraductal migration) and 6-month (abdominal pain, septic shower and embedded stent) groups - 6.1% 9.1% respectively, = 0.40. All strictures resolved at the end of the stenting course, but the stenting course was variable from 3 to 22 months. The recurrence rate for stenting courses lasting for up to 120 d was 71.4% and 21.4% for stenting courses of 121 d or over ( = 0.03). There were 28 patients that were treated with a single ERCP with Kaffes, 21 with removal after 120 d and 7 within 120 d. There was a significant improvement in stricture recurrence when the Kaffes was removed after 120 d when a single ERCP was used for the entire stenting course (71.0% 10.0%, = 0.01).
CONCLUSION
Utilising a single Kaffes intraductal fully-covered metal stent for at least 4 months is safe and efficacious for the management of post-transplant anastomotic strictures.
