Published: August 2024

Oil palm fruit is an essential product derived from the palm trees. The stress associated with palm fruit harvesting, particularly from tall palm trees, supports the call for a technology transition from manual to mechanical harvesters. The study's objective is to evaluate the performance and also determine the machine parameters and ergonomics of the oil palm harvester to aid in adopting the machine, training farmers, and addressing operator inefficiencies. The study was conducted using a cross-sectional survey involving 261 farmers, an observational, experimental, and evaluative approach through multiple testing procedures based on the ground theory. The study assesses oil palm harvesting practices, highlighting the prevalence of sickle-pole harvesters (76%), despite ergonomic challenges causing operator fatigue and health risks. Mechanical harvester adoption is limited (3%) due to high costs and availability, contrasting accessible manual harvesters. Performance evaluation reveals a reduction in the expected improvement in the mechanical harvester’s capacity by 65 fresh fruit bunches (FFB), mainly attributed to operator inefficiencies, yet it proves 22 % more efficient than manual methods (P-value of 0.8287 was obtained under 5 % significance level). A predictive model underscores the mechanical harvester's potential, hindered by persistent low adoption due to cost considerations. The study addresses ergonomic concerns, proposing modifications for vibration-induced fatigue. Emphasizing the need for stakeholder engagement and policies to promote mechanized agriculture in Ghana, the research contributes valuable insights to precision agriculture and ergonomic design.

Published: August 2024

Abstract
Morbid obesity in infancy or early childhood is a challenging disease to manage. Here, we present the case report of the successful management of a 2-year-old girl child with morbidly obesity who was bedridden and had sleep apnoea and underwent laparoscopic sleeve gastrectomy. Bariatric surgery in this age group comes with a lot of decision-making challenges and technical and ethical considerations, and literature is scant on paediatric bariatric surgery. We describe the case and associated challenges in detail in this report.
Umbilical pilonidal sinus with the urachal tract: A case managed with umbilicus-preserving laparoscopic urachal cyst and tract excision
Authors: Khemchand Agrawal Kavita , Kundal Ajay , Saxena Puja , Gill Ravneet Kaur 
Published: August 2024

Abstract
The umbilical pilonidal sinus (UPS) is a rare clinical entity and is not easily diagnosed unless there is a high suspicion. Pilonidal sinuses are most frequently seen around the gluteal cleft, but occasionally can be observed on other areas of the body, including the breast, webs of fingers, axilla and umbilicus. UPS is one of the rarest subtypes. Risk factors for UPS are similar to those for gluteal cleft pilonidal cysts and include young age, male gender, obesity, hairy body and poor personal hygiene. The traditional approach of treatment is usually conservative or surgical excision of the sinus with or without umbilectomy through the open technique. We discuss a case of UPS in an adult male having a concurrent urachal cyst with the urachal tract. We report our experience in laparoscopic management of this case after the failure of a conservative approach, with favourable outcomes at 1-year follow-up.

Published: August 2024

Abstract

Introduction:
Post-operative analgesia is an important component of patient satisfaction and early discharge from the hospital. A variety of modalities have been tested and are still evolving. The present study is one such evaluation of a novel technique of laparoscopy-guided transverse abdominis plane (LTAP) block for post-operative analgesia in laparoscopic cholecystectomy.

Patients and Methods:
A prospective randomised control trial was conducted to verify the effectiveness of LTAP block over port site local anaesthesia infiltration (PSLAI) for post-operative analgesia in patients undergoing laparoscopic cholecystectomy. This study was done over a period of 18 months in a tertiary hospital. A total of 84 patients were recruited and were divided equally into two groups (LTAP and PSLAI).

Results:
There was no statistical difference between the two groups with respect to gender distribution, comorbidities, number of gallstones, duration of symptoms and surgery time. The rescue dose of diclofenac requirement was less for the LTAP group in comparison to the PSLAI group. No difference was observed in the pain score at 1st h. However, LTAP proved efficient later in the post-operative course (6 h, 24 h and at discharge). There was significant a difference in the pain scores between the two groups, favouring the LTAP group. Hospital stay in the LTAP group was less in comparison to the PSLAI group.

Conclusion:
LTAP block is an effective method of post-operative analgesia. It impacts analgesia to the whole anterior abdominal wall for a prolonged period when compared to the PSLAI without adding any extra procedural time.
Initial experience of SSI Mantra robot-assisted Transabdominal pre-peritoneal repair of primary ventral hernias
Authors: Mehrotra Magan , Kumar Chukka Gautam 
Published: August 2024

Abstract

Introduction:
Small and medium sized primary midline ventral hernias are best treated by pre-peritoneal mesh placement. This helps in prevention of complications related to intra-peritoneal mesh placement. The challenges we face while performing laparoscopic transabdominal pre-peritoneal (TAPP) procedure can be overcome by robot-assisted TAPP (rTAPP), and we present our initial experience with the same. We describe the surgical technique used in rTAPP using the relatively new SSI Mantra platform for primary midline ventral hernia repair and evaluate its feasibility and present the outcomes.

Patients and Methods:
we performed rTAPP for primary midline ventral hernia repair in 10 patients from July 2023 to September 2023. Demographic patient data, hernia characteristics and peri-operative outcomes were measured.

Results:
A total of 10 patients underwent elective rTAPP for primary midline ventral hernia, of which 7 were male and 3 were female. The average defect size was 3.2 cm. The average operative time was 113 min. All the patients were discharged within 24–36 h after the procedure. There were no deaths. No post-operative complications such as haematoma, clinically significant seroma, deep or superficial wound infection or recurrence were noted within 30 days.

Conclusion:
rTAPP is a technically feasible procedure for the repair of small- and medium-sized midline ventral hernias with defect sizes up to 5 cm. SSI Mantra robotic platform provides the same benefit that other conventional robotic platforms provide at a much lesser cost. Further studies looking at the cost–benefit ratio are required to substantiate the above.
Low-pressure pneumoperitoneum with intraoperative dexmedetomidine infusion in laparoscopic cholecystectomy for enhanced recovery after surgery: A prospective randomised controlled clinical trial
Authors: Gaiwal Sucheta , Palep J H , Mirkute Rohini , Prasad Nimitha , Kush Mehta 
Published: August 2024

Abstract

Background:
Enhanced Recovery After Surgery (ERAS) programs represent a shift in perioperative care, combining evidence-based interventions to reduce surgical stress to expedite recovery. ERAS requires cohesive team efforts to facilitate early discharge and reduce hospital stays. Anaesthesia and pneumoperitoneum management within ERAS play crucial roles in influencing postoperative outcomes. Laparoscopic cholecystectomy is widely acknowledged as the foremost approach for managing symptomatic gallstone disease due to its minimally invasive nature and favourable recovery. It has been demonstrated that increased abdominal pressures with prolonged CO2 exposure produce changes in cardio-vascular and pulmonary dynamics, which can be minimized by insufflating at minimum pressure required for adequate exposure, as advocated by European endoscopic guidelines. Dexmedetomidine, a highly selective alpha-2 adrenoreceptor agonist, has gained attention in anaesthesia armamentarium due to its sedative, analgesic, sympatholytic, and opioid-sparing properties. For multimodal opioid sparing postoperative pain management it’s advantageous.

Aim:
To evaluate combined effect of low-pressure pneumoperitoneum and intra-operative dexmedetomidine infusion in laparoscopic cholecystectomy for ERAS.

Patients and Methods:
160 patients of American Society of Anaesthesiologists (ASA) score 1 and 2, undergoing elective laparoscopic cholecystectomy were randomized into low pressure pneumoperitoneum (10-12 mmHg) and standard pressure pneumoperitoneum (13-15 mmHg) groups. Each group is subdivided into, no Dexmedetomidine (ND) and with Dexmedetomidine (WD) infusion (0.7 mcg/kg/hr) intra-operatively. Thus, 40 patients in each of the 4 study arms. Perioperative variables were collected and analysed.

Results and Conclusions:
Low pressure pneumoperitoneum with intra-operative Dexmedetomidine infusion (0.7 mcg/kg/hr) resulted in stable hemodynamics, reduced post-operative pain, no requirement of additional analgesics and early discharge. Thus, synergistic impact of these interventions significantly improved postoperative outcomes when used as part of ERAS protocols.
Giant left spontaneous diaphragmatic hernia repair via combined laparoscopic and thoracoscopic approaches
Authors: El Maksoud Walid M. Abd 
Published: August 2024

Abstract
Spontaneous diaphragmatic hernias (DHs) are uncommon, yet potentially hazardous. To prevent consequences, timely diagnosis and treatment are necessary. A 54-year-old male presented to the emergency room with dyspnoea, cough and tachycardia; he had no history of trauma. Diagnostic imaging revealed a substantial left DH, indicating the need for surgical intervention. The intraoperative examination identified a transverse colon and omentum herniation. Dissection, reduction of the contents, primary sutures of the defect and dual mesh reinforcement accomplished the laparoscopic and thoracoscopic DH repair. This case underscores the importance of timely detection, precise surgical intervention and comprehensive post-operative monitoring when utilising a multidisciplinary approach to manage DHs. It serves as a reminder to exercise caution regarding DHs, particularly in circumstances devoid of traumatic aetiology and the benefits of combined laparoscopic and thoracoscopic approaches.

Authors: Azhria Intan Nurun , Arina Yuliana Mahdiyah Daat , Wahyukundari Melok Aris , Kiswaluyo  
Published: August 2024

Introduction: Pregnancy is a risk factor for periodontal disease due to an increase in hormones which causes a change in response of periodontal tissue to the accumulation of plaque and calculus that can increase the occurrence of inflammation of the gingiva and periodontal disease. Pregnant women in coastal areas have a high risk of periodontal disease because the majority consume seafood that contains high calcium and phosphorus, which allows for increased calculus formation. Periodontal disease during pregnancy has an adverse impact on the health of the fetus. Therefore, it is important to pay attention to the health of the periodontal tissues of pregnant women. This study aims to examine the description of health and periodontal treatment needs in pregnant women in the coastal area of Puger, Jember.
Material and Methods: This type of research is descriptive observational with a cross sectional study on 70 subjects selected by purposive sampling technique. Data were obtained based on the results of the Community Periodontal Index of Treatment Needs (CPITN) examinations and questionnaire interviews regarding oral health.
Results and Discussions: Health status of periodontal tissues of pregnant women in the coastal area of Puger Beach mostly (75,71%) had supra or subgingival calculus (CPITN score 2), there were periodontal pockets and there were no pregnant women with healthy periodontal tissue conditions. Types of periodontal treatment needs that are needed by all pregnant women are scaling and root planing and improving oral hygiene (Treatment Needs/TN 2).
Conclusion: Pregnant women in the coastal area of Puger Beach all experience periodontal disease so they need periodontal treatment.
Ulcer Traumaticus et Causa Trauma Occlusion
Authors: Dewi Amalia Eka Setya , Sidiqa Atia Nurul 
Published: August 2024

Introduction: A Traumatic Ulcer is a type of ulcer that is caused by local factors. Traumatic ulcers usually occur on the soft tissues in the oral cavity and can be caused by many factors, one of which is occlusion trauma.
Case: The clinical picture of an ulcer is that of an ulcer on the oral mucosa in an acute inflammatory state, including varying degrees of pain, redness, and swelling in various sizes and shapes. The initial lesion in traumatic ulcers is usually felt by people in the form of annoying pain.
Case Management: Medication therapy such as Aloclair gel containing olyvinylpyrrolidone (PVP) which has mucoprotective activity works by forming a layer over the ulcer that will protect the affected nerve endings so as to prevent irritation and reduce pain in the ulcer. Hyaluronic acid and Aloevera support the natural healing process of damaged tissue.
Discussion: A traumatic ulcer lesion can heal on its own within 10 to 14 days if the irritant or cause is removed because during this time there will be a process of keratinization and renewal of oral mucosal epithelial cells.
Conclusion:Traumatic ulcers can heal within a few weeks by addressing the causative factors, administering medication, and encouraging patients to maintain good nutrition and oral health.
