Robotic Adrenalectomy: A 10-Year Clinical Experience at a Tertiary Medical Center.

Background and Objective: Laparoscopic adrenalectomy is now the preferred approach for most adrenal tumors. As minimally invasive surgery departments gain familiarity with the robotic platform, the safety profiles and efficacy of robotic adrenalectomy has been an area of continued discussion. The objective of this study is to outline our experience with transitioning to the robotic platform and determining the effectiveness and safety of transperitoneal robotic adrenalectomy. Methods: We performed a single-center, retrospective review of 37 patients who underwent transperitoneal robotic adrenalectomy between August 1, 2010 and August 31, 2020. Outcomes included patient morbidity, hospital length of stay, operative time, estimated blood loss, gland volume, pathology, and postoperative complications. Results: Sixty-five percent of the total robotic adrenalectomies were of the left adrenal gland. The average operating room time was 213 minutes. The average gland volume was 71 cm3, estimated blood loss was 74 mL and length of stay was 1.4 days. There were no significant differences in outcomes between the right and left total robotic adrenalectomies. Approximately one-third of our cohort had an adrenal cortical adenoma, while only one patient had adrenal cortical carcinoma. Four patients experienced postoperative complications that resulted in unplanned hospital readmissions and there was one mortality. Conclusions: Although the standard of care for most adrenal tumors is laparoscopic resection, our 10-year experience has shown that robotic adrenalectomy is highly effective and can be a valuable tool in the community and academic setting.

Reoperations for Long-Term Complications Following Laparoscopic Adjustable Gastric Banding: Analysis of Incidence and Causality.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) gained popularity in the early 2000s as a purely restrictive procedure with modest weight loss. The potential for complications requiring reoperation has since become evident. A retrospective review was performed to determine the incidence of long-term complications and predictive factors requiring surgical reintervention after LAGB. METHODS: Institutional review board approval was obtained, and a retrospective review of 200 consecutive patients undergoing LAGB over a period of six years was conducted at a single institution with American Society of Metabolic and Bariatric Surgery Center of Excellence designation. Data were collected on patient characteristics, comorbid conditions and complications requiring reintervention. Statistical analysis was performed using SPSS Statistics software (IBM Corp., Armonk, NY). RESULTS: Of the 200 patients, 176 (90.7%) were female with an average age of 53.6 years and preoperative body mass index (BMI) of 44.2 kg/m2. The average follow-up was 46 months. Complications occurred in 55 (28.4%) patients with band slippage/prolapse as the most common need for reoperation. Younger age, lack of comorbidities and diet/exercise compliance were associated with reintervention. CONCLUSIONS: LAGB has a high rate of reoperation secondary to complications associated with younger age. Alternative bariatric procedures may be more appropriate in these patients who have fewer comorbid conditions and are motivated to improve his or her health.

Urinary Bladder Matrix Reinforcement for Laparoscopic Hiatal Hernia Repair.

BACKGROUND AND OBJECTIVES: Synthetic mesh reinforcement during laparoscopic hiatal hernia repair (LHHR) reduces recurrence. Biologically derived mesh is also associated with reduced recurrence. Urinary bladder matrix (UBM), a biologically derived extracellular matrix mesh, has shown clinical success. We wanted to determine the safety and efficacy of LHHR with porcine UBM reinforcement. METHODS: This retrospective, single-surgeon study reviewed clinical data on patients who underwent LHHR from August 2009 through May 2014, with diaphragmatic reinforcement with porcine UBM mesh. Primary outcomes were (1) recurrence-a >2-cm defect above the diaphragm at 3 months; (2) intra- and postoperative complications; (3) pre- and postoperative esophageal reflux (GERD) or dysphagia; and (4) cessation of proton pump inhibitor (PPI). RESULTS: Sixty-two patients who had LHHR with UBM mesh were studied (mean age, 62 years, 53 women, mean body mass index 32.7 kg/m2) Before surgery 98% had GERD, 19% had dysphagia, and 98% were on PPI. Postoperative UGIS was performed on 66% 3 months after surgery, and 19% had a recurrence of >2 cm; 56% remained on PPI, and 16% (P < .001) remained symptomatic. Dysphagia improved in 75% (P = .05). No intraoperative complications were recorded. One postoperative mortality occurred secondary to an unrelated cardiac event. CONCLUSIONS: UBM mesh was effective and safe for LHHR. In addition to reducing the rate of recurrence compared to unreinforced primary repair, the properties of UBM, including site-specific constructive tissue remodeling, may add benefits over other biologic products. This study represents an evaluation of UBM mesh in a large cohort of patients who underwent LHHR.

Two-trocar cholecystectomy by strategic laparoscopy for improved cosmesis (SLIC).

BACKGROUND AND OBJECTIVES: Until the advent of singleincision laparoscopic surgery, few advances were aimed at improving cosmesis with laparoscopic cholecystectomy. Criticisms of the single-incision laparoscopic surgery technique include a larger incision and increased incidence of wound-related complications. We present our initial experience with a novel technique aimed at performing strategic laparoscopy for improved cosmesis (SLIC) for cholecystectomy. METHODS: Twenty-five patients with biliary symptoms were selected for SLIC cholecystectomy. Access to the abdomen was obtained with a 5-mm optical trocar in the left upper quadrant and a 5-mm trocar in the umbilicus. Retraction was performed by a transabdominal suture in the dome of the gallbladder and a needlescopic grasper. Age, American Society of Anesthesiologists score, body mass index, operative time, length of stay, pathology results, and short-term complications at follow-up were prospectively recorded. RESULTS: The 25 female patients had a mean age of 34.3 years and mean body mass index of 24 kg/m(2). American Society of Anesthesiologists scores ranged from 1 to 3. The mean operative time was 51.3 minutes. Pathology revealed chronic cholecystitis in all patients. All procedures were performed on an outpatient basis. The only complication was one ultrasonography-documented deep vein thrombosis. All 25 planned SLIC cholecystectomies were successfully completed. CONCLUSIONS: SLIC cholecystectomy is feasible and safe. This technique decreases the cumulative incision length, as well as the number of incisions, leading to very desirable cosmetic results in patients with a favorable body habitus and surgical history.
