ABSTRACT

Robot-assisted general surgery has become increasingly common in the Australian public sector since 2003. It provides significant technical advantages compared to laparoscopic surgery. Currently, it is estimated that the learning curve for surgeons starting off with robotic surgery is complete after 15 cases. This is a retrospective case series, following the progress of four surgeons with minimal robotic experience over 5 years. Patients undergoing colorectal procedures and hernia repairs were included. 303 robotic cases were included in this study, 193 colorectal surgeries and 110 hernia repairs. 20.2% of colorectal patients experienced an adverse event and 10.0% of hernia patients had a complication. The learning curve was correlated to the average docking time, and it was found that this was complete after 2 years, or after a minimum of 12 to 15 cases. Patient length of stay decreases as surgeon experience increases. Robotic surgery is a safe approach to colorectal surgery and hernia repairs with some potential benefits in terms of patient outcomes as surgeon experience increases.

ABSTRACT

BACKGROUND: Pelvic exenteration surgery is complex, necessitating co-ordinated multidisciplinary input and improved referral pathways. A state-wide pelvic exenteration multidisciplinary team (MDT) meeting was established in SA and the outcomes of this were audited and compared with historical data. METHODS: All patients referred for discussion between August 2021 and July 2022 to the SA State-wide Pelvic Exenteration MDT were included in this study. MDT discussion centred around disease resectability, risk versus benefit of surgery, and need for local or interstate referral. Prospective data collection included patient demographics and MDT recommendations of surgery, palliation, or referral. Patients referred for surgery locally or interstate were compared with a retrospective patient cohort treated previously between January and December 2020. RESULTS: Over 12 months, 91 patients were discussed (including nine multiple times), by a mean of 18 meeting participants each month. Forty-eight patients (58.5%) had primary malignancy, 25 (30.5%) recurrent malignancy, and 9 (11.0%) had non-malignant disease. Colorectal cancer was the most common presentation (56.1%), followed by gynaecological (30.5%) and urological (6.1%) malignancy. Pelvic exenteration surgery was recommended to be performed locally in 53.7% of patients and the remainder for non-surgical treatment, palliation, or re-discussion. During this time, 44 patients underwent surgery locally (versus 34 in 2020) and only 4 referred interstate (versus 8 in 2020). CONCLUSION: The establishment of a dedicated state-wide pelvic exenteration MDT has resulted in better coordination of care for patients with locally advanced pelvic malignancy in SA, and significantly reduced the need for interstate referral.

ABSTRACT

BACKGROUND: Colorectal cancer (CRC) is rising in incidence in young adults, and this observation is currently unexplained. We investigated whether having a personal history of type 2 diabetes mellitus (T2D) was a potential risk factor for young-onset colorectal cancer (YOCRC). METHODS: The South Australian Young Onset (SAYO) CRC study is a series of young adults with CRC below age 55. Ninety unrelated YOCRC cases were recruited to the study. Personal history and detailed family history of T2D were obtained at face-to-face interview and confirmed from medical records. Whole exome sequencing was conducted on germline DNA from each CRC case. Controls for personal history studies of T2D were 240 patients with proven clear colonoscopies and no known CRC predispositions. RESULTS: The median age of YOCRC cases was 44 years (18-54) and of controls was 45 years (18-54), and 53% of both cases and controls were females (P = 0.99). Left-sided (distal) CRC was seen in 67/89 (75%) of cases. A personal history of T2D was confirmed in 17/90 (19%) YOCRC patients compared with controls (12/240, 5%; P < 0.001; odds ratio = 4.4; 95% confidence interval, 2.0-9.7). YOCRC patients frequently reported at least one first-degree relative with T2D (32/85, 38%). Ten of 87 (12%) of YOCRC cases had CRC-related pathogenic germline variants, however, no pathogenic variants in familial diabetes-associated genes were seen. CONCLUSIONS: Though the mechanism remains unclear, our observations suggest that there is enrichment for personal history of T2D in YOCRC patients. IMPACT: A diagnosis of T2D could therefore potentially identify a subset of young adults at increased risk for CRC and in whom early screening might be appropriate.

ABSTRACT

Gallstone ileus is an uncommon presentation among acute surgical patients. Its diagnosis is often delayed due to its non-specific clinical presentation. We report the case of an 81-year-old gentleman with a 2-day history of small bowel obstruction (SBO). He had a history of gallstone disease and no past surgical history. Plain abdominal radiography was consistent with SBO. A computed tomography (CT) abdomen scan would be warranted given the presentation of SBO in a virgin abdomen. However, this case emphasizes the importance of early CT imaging in a case of suspected gallstone ileus given that the diagnosis could not be made on plain abdominal radiography. CT abdomen is superior in detecting small amounts of gas and at discriminating soft tissue density.

ABSTRACT

BACKGROUND: Adenoma detection rate (ADR) has shown to be an independent predictor, to reduce the rate of interval colorectal cancer. Endocuff Vision is a relatively new device that has shown promise to improve the ADR. The primary objective was to conduct a randomized controlled trial to compare Endocuff Vision-assisted colonoscopy (EVAC) with standard colonoscopy (SC). The primary outcome of the study is ADR and the secondary outcomes are caecal intubation rate, terminal ileum intubation rate, scope withdrawal time, quality of bowel preparation and adverse events. METHODS: A randomized controlled trial was performed to compare EVAC versus SC. All patients who presented to the endoscopy suite at the Queen Elizabeth Hospital were assessed for eligibility. Patients were recruited from 15 June 2016 to 20 January 2017. A total of 360 patients were included; 40 were excluded. The patients were randomized using block randomization; 138 patients were recruited to SC and 182 to EVAC. RESULTS: A total of 231 polyps were retrieved during the study period. Polyp detection rate (PDR) was high in both groups: 53% in the EVAC group versus 41.1% in SC. This was statistically significant with a P-value of 0.035. ADR was similarly high in both groups: 36.81% in EVAC group versus 28.99% in SC group. ADR did not reach statistical significance. CONCLUSIONS: EVAC does improve the PDR. Though the ADR did not reach statistical significance, there is a trend towards improved adenoma detection and there is statistical significance in the overall PDR.

ABSTRACT

BACKGROUND: Laparoscopic ventral hernia repair provides several benefits over the open approach. Intraperitoneal surgical mesh placement without fascial defect closure is associated with increased seroma formation and other adverse hernia-site outcomes. Transfascial sutures and tacs for fascial closure and surgical mesh fixation are associated with greater post-operative pain. Robotic-assisted ventral hernia repair (rVHR) may afford benefits of the laparoscopic approach while facilitating a more robust and less painful repair. METHODS: Consecutive patients managed by rVHR from May 2015 to August 2018 were identified from a prospectively maintained robotic database. Retrospective review of this data was performed. RESULTS: Fifty patients underwent rVHR during the study period. Median body mass index was 31 (interquartile range (IQR) 29-34). Forty-eight had previous abdominal surgery. Forty-seven hernias were midline and three were lateral. Regarding hernia width, 15 were <4 cm wide, 32 were 4-10 cm and three were >10 cm. Median total anaesthetic time, docking time and surgical console time were 214 min (IQR 182-252), 5 min (IQR 4-8) and 144 min (IQR 104-174), respectively. No major intra-operative complications occurred. No documented cases of adhesional complications or chronic post-operative pain have occurred. To date, two recurrences have occurred in our series. Median length of hospital stay was 3 days (IQR 2-4). CONCLUSION: We describe our rVHR technique and report on our series and early experience, showing that rVHR can be performed safely with good patient outcomes. We demonstrate a team approach to achieving a safe transition to new technology.

ABSTRACT

Neostigmine is an acetylcholinesterase inhibitor that is increasingly used as a medical treatment in cases of pseudo-obstruction. It has a well-recognized side-effect profile that includes bradycardia and bronchospasm. We present a case of colonic perforation after administration of neostigmine in the treatment of pseudo-obstruction.

ABSTRACT

PURPOSE: Perianal sepsis is traditionally treated by incision and drainage, with packing of the residual cavity until healing. This study was designed to show that perianal abscess may be safely treated by incision and drainage alone. METHODS: Healing times, analgesic requirements, pain scores, abscess recurrence, and fistula rates were compared between two randomized groups treated with and without packing of perianal abscess cavities. RESULTS: Fifty patients were recruited (7 lost to follow-up): 20 in the packing and 23 in the nonpacking arm. The groups were comparable in terms of age and gender distribution, type and size of abscess, and the presence of a fistula at operation. Mean healing times were similar ( P = 0.214). The rate of abscess recurrence was similar ( P = 0.61). Postoperative fistula rates were similar ( P = 0.38). Pain scores at the first dressing change were similar ( P = 0.296). Although pain scores appeared much reduced in the nonpacking arm, this did not attain statistical significance. CONCLUSIONS: Our pilot study indicates that perianal abscesses can be managed safely without continued packing of the cavity without any obvious complications.
