Case 2: Preoperative Optimization of Diabetic Patient
Patient Demographics
- Age: 58 years
- Sex: Female
- Occupation: Office manager
Chief Complaint
"I need surgery for a hernia that keeps getting stuck."
History of Present Illness
The patient presents for preoperative evaluation prior to elective incisional hernia repair. She developed an incisional hernia following open cholecystectomy 3 years ago. Over the past year, the hernia has enlarged significantly and she has experienced three episodes of incarceration requiring emergency department visits for manual reduction. Her most recent episode was 2 weeks ago. She is now scheduled for elective mesh hernia repair.
Past Medical History
- Type 2 diabetes mellitus for 15 years with HbA1c 9.2%
- Peripheral neuropathy
- Chronic kidney disease stage 2 (creatinine 1.3 mg/dL)
- Obesity (BMI 38)
- Obstructive sleep apnea on CPAP
- Former smoker (quit 6 months ago, 30 pack-year history)
Preoperative Optimization
Glycemic Optimization:
- HbA1c 9.2% indicates poor glycemic control
- Goal: HbA1c <8% prior to elective surgery
- Surgery delayed 6 weeks for intensive diabetes management
- Endocrinology consultation for medication adjustment
- Patient started on GLP-1 agonist in addition to metformin
- Repeat HbA1c at 6 weeks: 7.8%
Smoking Cessation:
- Patient quit 6 months ago - excellent
- Mucociliary function typically recovers by 8 weeks
- Reduced wound complication risk with cessation
Weight Optimization:
- Discussed weight loss goals
- Referred to bariatric medicine
- Lost 8 kg over 6-week optimization period
- Reduced surgical difficulty and wound complications
Sleep Apnea Management:
- CPAP compliance verified
- Instructed to bring CPAP device to hospital
- Anesthesia notified for airway planning
- Postoperative continuous pulse oximetry ordered
Outcome
Surgery performed after 6-week optimization period. Laparoscopic incisional hernia repair with mesh completed without complication. Patient discharged same day with CPAP use continued. Follow-up at 2 weeks showed well-healed incisions and no recurrence at 6 months.
Teaching Points
- Elective surgery allows time for preoperative optimization
- HbA1c >8% associated with increased surgical site infections
- Smoking cessation at any time before surgery improves outcomes
- OSA patients require special perioperative precautions
- Weight loss reduces technical difficulty and wound complications
