Abstract

Objective:

Adrenal surgery remains a distinct surgical challenge. Technical challenges associated with laparoscopic adrenalectomy are tumour size, haemorrhage control and oncological compromise. Hand-assisted laparoscopic (HAL) adrenalectomy, utilizing a hand-port device, offers minimally invasive surgery with the advantages and safety of tactile feedback. We aimed to assess the efficacy of HAL for patients requiring adrenalectomy for tumours over 5 cm in size.

Context:

Hand-assisted laparoscopic surgery is used in several surgical specialities over totally laparoscopic surgery to manage sizeable pathology, reduce operating time and conversion rates. HAL adrenalectomy is demonstrated in this series as a safe alternative to laparoscopic adrenalectomy for large adrenal tumours.

Design:

A retrospective analysis of all HAL adrenalectomies performed over 8 years (October 2006-May 2015) by a single surgeon was performed. This case series is the largest study of this technique.

Patients:

All patients who were fit for surgery with adrenal tumours (over 5 cm) were included.

Analysis:

Primary endpoints were overall mortality, operating time, hospital stay, complications and conversion to open surgery.

Results:

A total of 56 patients underwent the procedure. A total of 43 had unilateral and 13 bilateral lesions. Most lesions (45) were histologically benign. These included functioning and non-functioning tumours. Median tumour size was 8 cm (range 5-19 cm). There was one (1.8%) intra-operative conversion and no peri-operative mortality. Postoperative complications occurred in 8 (14%) patients, all self-limiting. The median length of stay was 6 days (range 2-21). There was one recurrence of pathology with repeat surgery.

Conclusion:

Hand-assisted laparoscopic surgery offers a safe reproducible approach to adrenal surgery combining minimally invasive surgery with tactile integration. Although previously described in small numbers, this represents the largest case series to date. HAL is a safe minimally invasive surgical option for larger tumours, including malignancies. The HAL technique may additionally offer a shorter learning curve for trainee adrenal surgeons.

Ethnic Identity within a Larger Culture

Ethnic Identity within a Larger Culture

Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

5-Number Summary

In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Types of Reports I: Hands-off Report

Types of Reports I: Hands-off Report

A hand-off report, also known as a change-of-shift report, is a crucial nursing process that ensures the smooth transition of patient care responsibilities between nursing staff.
Following are the key components and categories of hand-off reports:
Purpose and Process:

Muscles of the Forearm that Move the Hand and Fingers

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

Chemotherapy-Induced Nausea and Vomiting: 5-HT₃ Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...
